Plasticity in steel is characterized by an appreciable amount of plastic flow which precede strain-hardening. This study is devoted to an evaluation of the out-of plane flexural rigidities of yielded steel plates at the instance of plate buckling. An emphasis is on the fact that a steel plate has finite values of flexural rigidities in this range due to the deformation restraint which is given rise to by the effects of support around the plate edges. Assuming that the stress-strain response of steel in this range follows the incremental plasticity theory for nonhardening material together with von Mises yield criterion, an explicit formulation are derived for the moduli to relate the flexural rigidities of plate. Comparison is made of the magnitude of so derived moduli with those in the strain-hardening range of mild steel. It is found that difference in the moduli between the both ranges is not significant from engeneering point of view. It is shown that column is a special case of plate and buckles when its tangent modulus vanishes. Local buckling of steel plate with its all four edges simply supported is examined by the moduli derived. And the difference of role of plastic flow and strain-hardening between column and plate is made clear.

Prediction of damage is important in evaluating the earthquake response of reinforced concrete (RC) structures. Damage prediction is usually measured in term of ductility factor. However, concerning reinforced concrete structures subjected to a lot of cycles of severe loads, a combination of maximum displacement response and cyclic deterioration of stiffness and load carring capacity may cause RC structures to collapse. Damage due to maximum displacement response and cyclic deteriolation can be made over to ductility factor and cumulative fatigue damage, respectively. So, from viewpoint of collapse, it must be investigated the properties of lowcycle fatigue for RC structures. In order to investigate low-cycle fatigue damage in RC columns, seven reinforced concrete frames with rigid beams have been tested. As the results, restoring force characteristics, experimental equation of stiffness deterioration, △δ-N_f curve and cumulative fatigue damage hypothesis have been formulated. Then, the dynamic response analyses have been carried out by applying the restoring force characteristics obtained from the tests and the results of the dynamic response analyses have been evaluated by the concept of cumulative fatigue damage formulated from the tests. From the results of the study reported in this work, it is concluded that : (1) The Wohler curve (△δ-N_f curve) can be shown as Fig. (5). (2) As shown in Fig. (7), the linear cumulative fatigue damage hypothesis can not be applied for low-cycle fatigue damage of reinforced concrete columns. (3) The non-linear cumulative fatigue damage factor for reinforced concrete columns can be suggested in the form of Eq. (7) and Eq. (8). (4) In case that the maximum displacement response is in the work-hardening region of skeleton curve, the seismic damage of RC columns depends on only the ratio of the maximum displacement response vs. the collapse displacement of the column and the damage caused by cyclic deterioration (cumulative fatigue damage) can be neglected, i.e., only ductility factor is important for prediction of damage in this domain. (5) In case that the maximum displacement response is the falling branch of the skeleton curve, the seismic damage of RC columns must be evaluated by a combination of the maximum displacement response and the cumulative fatigue damage. The seismic damage caused by low-cycle fntigue becomes 20-35% of the full damage at that time, i.e., not only ductility factor but also cumulative fatigue damage is important for evaluating seismic damage in this domain. (6) The seismic damage factor decreases hyperbolically as the period T increases. (7) When T≤0.1sec, the seismic damage increases rapidly as the ratioβ=mz_<max>/Q_y increases a little, and the structure collapses suddenly, just in case β=1.0. (8) Though the structures were subjected to various kinds of eathquake motions, cumulative hysteretic absorbed energy has the tendancy to be constant for each period at collapse of the structures.

Secondary structures mounted on primary structures such as water tanks and towers on buildings are exposed to the amplified floor motion under earthquakes. The elastic responses of them have been almost made clear and various propositions on design spectra have been made on the elastic design basis. The inelastic responses of them, however, have been scarcely investigated and the ultimate resistance of those structures to earthquakes is still left uncertain. This paper aims to clarify a general feature of their inelastic behaviors. As for the inelastic behavior of the primary structure, the total energy input exerted by earthquakes may provide a sound measure for the structural damage. On the same context, emphasis is laid on the energy input of the secondary structure and the correspondence between the elastic response and the inelastic response is made clear in the light of the energy input. It is concluded that the inelastic response spectra for secondary structures can be readily depicted on the basis of the elastic response spectra of them.

The D_s-value means a reduction factor of the design seismic force for structures with inelastic deformability. D_s-values for shear type multi-story structures such as a weak-column type of buildings have been derived by considering the equilibrium between the input energy due to an earthquake and the absorbed energy by a building. Another typical type of structures is of weak-beam type which is expected to be equipped with large energy absorption capacity, but D_s-values for those stuctures have been left uncertain. In this paper, firstly a general law which governs the vertical distribution of the cumulated inelastic deformation (damage) is obtained and is expressed in terms of the stiffness ratio of beam to column. Next, based on the basic law, D_s-values for weak-beam type of steel buildings are derived analytically and the results are compared with those for weak-beam type of steel buildings are derived analytically and the results are compared with those for weak-column type of buildings.

Under the earthquake load, R/C short columns in framed structure may fail in shear unless enough transverse reinforcements are provided and at worst result in the collapse of whole structure. Up to the present, many researches have been perfomed on shear problems and various design formulas were derived. These formulas are fundamentally based on the assumption that the shear capacity V_u can be given by the equation V_u=V_c+V_<s'> where V_c denotes the contribution of concrte and V_s the capacity of analogous truss. V_c should correspond to the shear at the development of diagonal tension crack because the tension stress of web reinforcement begin to increase just after the occuring of that. On the other hand, it may be better that V_s is defined based on the shear at which the web reinforcements crossed by the diagonal crack yield. Standing on such basic concepts, the authors intended to quantify the values of V_c and V_s based on the results obtained from column shear tests. Obtained formula for V_c is based on the flexural bond stresses and from the statistical calculation for 175 sample specimens the value of 0.24 was obtained as the coefficient of variation. V_s was detemined as the function of p_w・_wf_y where p_w and _wf_y are the ratio of web reinforcement and the yield strength of that, respectively. The formula for V_s may be considered to correspond to the lower limit of the contribution of web reinforcement as mentioned above.

The method for estimating the settlement of spread foundation on Masa-do ground is presented through considering the behavior of compressibility from plate bearing test and confined compression test. The contents and results of this paper is summarized as follows; 1) The relationships between N-value and Nsw-value, coefficient of subgrade reaction and plate width etc. are presented and examined. Consequently, it becomes possible to estimate the immediate settlement from a small plate bearing test. 2) When the settlement after 15 minutes, which corresponds to the loading time, is regarded as immediate settlement, viscosity parameter becomes a simple equation. And when an arbitrary load increment ratio and an arbitrary amount of load is given, we can easily estimate an amount of settlement taking a certain time in each load step. Creep settlement increases according to the softness of the ground and the number of the load steps by the effect of viscosity parameter. 3) As the compression mechanism by the compression test is different from the mechanism by the plate bearing test, so their settlement are different from each other. These two settlement are compared and examined under some varieties of Nsw-value and load. It is necessary to use the coefficient of settlement conversion from the confined compression test in order to estimate the settlement of spread foundation. 4) From the plate bearing test, the confined compression test and Nsw-value, we can estimate an amount of settlement using the above mentioned procedure and its result.

In order to clarify the subjective attribute of sounds in terms of the evaluation of environmental noises, 12 psycho-acoustical experiments in 5 series were performed during the period of five years. All experiments were carried out in an acoustically treated listening room. Subjects were asked to estimate the impressions of sound stimuli using semantic scales of adjectives. In order to obtain the validity of study, a wide variety of subjects, semantic scales, and sound stimuli were adopted. Stimuli included artificial sounds, a variety of environmental noises, classic, popular and traditional musics, natural sounds and human voices of many types. To formulate the sematic scales, two sources were utilized. The first was the standard Japanese dictionary of Iwanami edition, from which all entries were reviewed to achieve 23 bipolar scales. The second was the Bunrui Goihyo, the authorized Japanese thesaurus edited by National Language Institute, from which all entries were again reviewed according to its categorical analyses to achieve 22 bipolar scales. Subjects were both trained and untrained. Untrained subjects included junior high school pupils, college students of both sexes, housewives, and the aged citizens. Their ages ranged from 12 to 75. The results of 12 experiments were analyzed by the principal factor methods using the program of S.P.S.S., 6th and 8th editions by Kyoto University. Through all 12 analyses, three orthogonal factors were extracted. The first factor, "the acceptability", represents the acceptable impression of sound, which is related to the overall total quality but not directly related to major physical characteristics of stimuli. The second factor, "the strength". corresponds well to the total acoustical energy of the stimuli. The third factor, "the sharpness", corresponds both to the high frequency components and the impulsiveness of stimuli. The findings were compared to the similar studies done both in Japan and abroad. Discussions were made on the differences among the studies.

In this paper, the authors are making systematic and experimental studies of a system, which generates the floor lmpact sound from actual floor slab, in order to determine quantitatively a relationship among various factors. As for the vibration characteristics of slab in the case of floor slab impact, the impedance characteristics under variable slab thickness, material, area, fixing etc. were investigated from various point of view by the application of the driving point impedance method for the time analysis. The impedance at the so-called forced response, corresponding to the impact time of an impact source was measured to consider the influence of the degree of slab edge fixing on the change in impedance characteristics at various impact points, and the whole time response was inquired to consider decrease in impedance at the frequency bands, which include fundamental and higher-order modes frequencies of the natural vibration, due to the decay time to vibration of slab. Distribution of the response velocity as a result of impact made on slab was determined to inquire into a possible relationship between this distribution and the effective sound radiating area. As for the sound radiation characteristics, the response to vibration as well as sound pressures directly under the excited point and in the directly lower room as a result of impact made on the slabs were determined to consider the correspondence of these three quantities from the time analysis result of the response waveform and at the same time to discuss the sound radiation resistance.

This paper describes the new method of model experiments on temperature distribution of room air on the basis of out-air temperature to predict the heat loads in large spaces. The first characteristic of this method is to use the model as a sort of simulator, that is to say, carring out model experiments and numerical calculation alternately, temperature distribution and heat loads of the room can be obtained directly. In this method similarity of heat resistances of the composing walls is not required. In this paper, studies on prediction of heating and cooling loads of the certain large halls (scale factor of the model is 1/20) were made. Furthermore the comparison of the predicted loads between this method and the method based on the relative temperature distribution of room air were made.

This is the ninth report of fundamental investigations for the planning of the public library system to community area. The paper describes the way of planning the library system to regional area based on our theory which had been carried out since the first report. We present here as a case study to plan the libray network actually to both regional area of Tokyo prefecture with aprox 11640 thousand population in 1740km^2, and Saitama prefecture with aprox 4820 thousand population in 3800km^2. In the case study we show that 1) how many libraries and bookmobiles shall be planned in the regions, 2) where they are located, 3) how many figures are given to each library : the number of books, the number of staffs etc, by number of book circulation per capita and the accessibility to the nearest library. In addition we show how the exsisting service levels are evaluated compared with the planning level by which the public planning authority can judge the situation and set up the additional plan for their library system.

This report is a theoretical consideration about agglomerating process of industries. We applied Input-Output Analysis to this subject. We originated some indexes using Inverse Matrix to supplement insufficiency of existing indexes. Those were Industrial correlative coefficient, Input concentration coefficient, Output concentration coefficient and Income generation ratio. We compared values of those indexes about all industries and indicated that there were two types of agglomerating force of productive groups. Type-1 : groups forming self-multiplicative agglomeration. Type-2 : groups forming stiff agglomeration. And we indicated that there were the kernel industries of agglomerating process and the industries which were utilized for instrument of labour by all industries including themselves. We concluded that these industries were very important for the agglomerating process.

本論文では, メタノールを燃料とする区画燃焼の模型実験で, 次のことを明らかにした。1) 区画燃焼の定常燃焼期の燃焼速度ど開口因子の関係には不連続性が存在し, 不連続点より開口因子が小さい領域では換気支配型燃焼性状を示し, 開口因子が大きい領域の定常燃焼期燃焼性状は燃料支配型となること(Fig.5)。2) フラッシュオーバーは上記の換気支配型の定常燃焼期を生ずる領域に特徴的な現象であること。すなわち, 燃焼速度の不連続点は, フラッシュオーバーの発生限界に対応すること。3) フラッシュオーバー発生の有無を定める換気条件としては, 区画内の燃料の熱分解条件に対して乱流拡散火炎を区画内で形成させるに足る新鮮空気が供給され得るかどうかが重要な基準となること。乱流拡散火炎の空気過剰率3〜4に対して, 本実験におけるフラッシュオーバー発生の有無の臨界空気過剰率はほぼ4と推定される。4) 本実験で扱った区画燃焼では, 燃焼速度と開口因子の間にヒステリシス特性が存在すること。従って, 燃焼速度が多価となる開口因子の条件が存在して, 上に指摘した燃焼速度の不連続点の存在は, この非線型特性に由来すると考えられること。
