最近の骨材生産事情は粒度特性を経済的に選択することを可能とするようになった。かかるとき, コンクリートのワーカビリチーなどの特性におよぼす骨材粒度の効果を定量的に評価し, 選択すべき粒度を確認する必要があると考える。そのためには, 粒度(粒子寸法分布)そのものの適正な数値化による記述が先決である。本報告では, 骨材のふるい分け試験結果を尊重し, それから計算される平均, 標準偏差, ゆがみ度, とがり度の4種の統計量を粒度パラメターと呼称して, 粒度の数値化を試みた。コンクリートの物性に影響の大きい細骨材の粒度の相違をはっきり特徴付けるため, 粗粒率基準の粒度パラメターを細, 粗骨材に共通した粒度の数値化法として提案した。その場合, 各基準ごとに階級内で一様分布する連続的変量を仮定して, 階級数が少なくても実際の分布を相応に評価することができるようにした。これにより, 骨材の実積率や表面積の推算, さらにはコンクリートのワーカビリチーなどの物性の解析に必要不可欠な骨材粒子の寸法と形状に関する既往の記述方法を改良, 集約し, 一般的な記述表示をある程度可能にした。今後は, ここに提案する粒度パラメターを用いてモルタルやコンクリートの諸物体, とくにワーカビリチーに及ぼす骨材粒度の影響を定量的に検討して, それら物性を複合材料として説明を可能にするとともに, 骨材資源の活用ならびにコンクリートの品質の向上を図っていきたい。その前提として, 骨材の実積率に及ぼす粒子寸法分布の効果について実験的研究を継続中であるが, 粗粒率基準による粒度パラメターの有効性が確認されている。これについては稿を改めて報告する予定でいる。

In the previous paper we reported the results of statistical analysis on excellence of vertical acceleration to horizontal one by method of factor analysis. In this paper the numerical results on effects of soil condition and source mechanism for excellence of vertical component were reported. The results obtained are as follows ; (1) Amplitude charactristics of the layered soil make the predominant period of observed vertical seismogram shorter than that of horizontal one. (2) According as the layered crust become soft, the increasing tendency of the amplitude rate of the soil is recognized. (3) The angles of incident of P-waves and SV-waves at the layered crust have very important effects on amplitude charactristics of layerd crust, but it is somewhat more significant owing to SV-waves. (4) According as the layered soil become soft, the increasing tendency of the rate of max. vertical amplitude charactristics of the soil to horizontal one is recognized. (5) Slip vector of the fault plane has very significant effects on vertical component of seismograms, especially dip slip type of fault strikehas have more significant effect than that of strike slip. (6) Dip angle of the fault strike has very significant effects on excellence of vertical component of seismograms. In this case of strike slip type of the fault, The vertical motions of the ground increase according as dip angle become little. But in case of dip slip type of the fault strike, the excellence of vertical component is somewhat more complex owing to the location of the station, fault strike and dip angle.

In the present paper, the initial imperfecton sensitivity of the axisymmetric dynamic buckling loads for clamped spherical caps, from λ=5 to 10, under a uniform step load is discussed. And the imperfection sensitivity of static, and astatic buckling loads are treated as well as dynamic buckling loads. The analysis is based on the finite element method and mode superposition method. This method avoids the direct finite element method of nonlinear effects and also takes an advantage of the important feature that a structural response is fundamentally due to several basic vibration modes. The governing equation is composed of a set of algebraic cubic polynominal equations in terms of the generalized modal displacements. The coeffcients in the equations for a shell with an initial imperfection are obtained through a simple matrix manipulation of those for the perfect shell and the coefficients in Fourier expansion of the imperfection. The result is confirmed by the present numerical analysis of buckling behaviour that an initial imperfection proportional to a buckling mode of a perfect caps is major for a static buckling load, and other nonproportional initial imperfections are minor. When the maximum value of any initial imperfection is about from 20 to 30 percents of the shell thickness, the static buckling load reduces severely, and accordingly the static buckling mode changes. Dynamic and astatic buckling loads are insensitive to any initial imperfection mode. The astatic buckling load can be considered as a lower limit not only for the theoretical value but also by a numerical response of the axisymmetric dynamic buckling of a calmped spherical cap with initial imperfectial under a uniform step load.

A soil has various damping mechanism such as internal viscous damping, hysteretic damping by material nonlinearity and radiation damping in wave motion. The dynamic behavior of a soil layer subjected a strong earthquake motion is in highly strained state under the above damping effects. So as to estimate the vibrational characteristics of highly strained and nonlinearly-behaved soil layers, one layered ground on the elastic base is solved by the equivalent linearization technique by use of complex eigen value analysis. The surface motion and in-ground behavior are clarified by examining the transfer function of the layer on surface response, strain distribution in a layer and corresponding strain-dependent rigidity reduction and hysteretic damping. The effect of the viscous damping, hysteretic properties and base condition on the ground response is discussed. The importance of damping effects and material nonlinearity under strong earthquake are presented.

A distribution map of maximum earthquake velocity amplitudes at the bed rock is proposed, since the extreme value distribution of the greatest yearly velocity of earthquakes can be obtained with the b value of Gutenberg and Richter's magnitude law and average annual earthquake occurrences as shown in Part 1. Where seismic activities determined from the deta during the period from 1885 to 1974 seem to be not adequate for historical events, the average annual rates of earthquake occurrences are modified. Main modified areas are the subduction zone of Japan. A relation of the average annual rate of earthquake occurrence and the recurrence period of large earthquake is considered.

Some analytical studies on a reinforced concrete hotel building, which was damaged beyond repair during the Oita earthquake of April 21, 1975, are presented in this paper. Analysis is started from idealizing the damaged building to a mechanical model. Linear static and dynamic responses of this idealized structure for which lateral motions are coupled with the torsional motion are studied and the influence of the torsional motion on elastic response is investigated. Summarizing the results of these analysis; (1) Ground motion due to the NS component of the Oita earthquake of April 21 1975 was quite severe to this hotel building. (2) Maximum base shear in torsionally coupled system is less than in the corresponding uncoupled system. (3) Effects of torsional motion on horizontal deflection and stresses of the building are not negligible. (4) Equivalent lateral force distribution for static analysis which is specified in the Uniform Building Code is more reasonable than that of the current Japanese Building Standard Law to this building. (5) It will be possible to evaluate the rigidity of the reinforced concrete shear walls by a simple method of analysis.

This series of papers describe an analysis method on soil-structure interactions through settlements of structures with pile foundations. In part 1, the foundamental equations for this analysis are introduced and some coefficients adopted in these equations are discussed. These equations are introduced under the following assumptions. 1. The one-dimentional consolidation theory is applied to the diluvial clay stratum which underlies the bearing stratum of piles. In this case, the distribution of stress in the diluvial clay stratum can be calculated by Mindlin's equation. 2. Piles are assumed to be elastic columns for axial load. The frictional resistance of the alluvial strata acting on pile surface is neglected. 3. The two cases of steel structure and reinforced concrete structure are treated. The deformation behaviors of these structures are elastic. But in the case of reinforced concrete structure, relaxation of stress due to creep of concrete is considered, too. In one-dimentional consolidation theory, the assumption that the coefficient of volume compressibility m_v and the coefficient of consolidation c_v are constants is usually adopted. In this theory, not only the same assumption but also the case that m_v and c_v are assumed to be variables can by treated.

A bar elastically restrained at both ends against rotation was analyzed based on differencial equation for the elastic bending of axially loaded member and commonly adopted yield conditions. The analytical results were compared with experimental results shown in ref. 11). Furthermore, cyclic behavior of a restrained bar was compared with one of a pin supported bar at both ends having the same slenderness ratio as the restrained bar. And the effects of the eccentricity of axial load on the behavior of a bar were investigated. Analytical results are as follows. 1) The analytical cyclic behavior fairly well predicted the experimental behavior, expect for the maximum compression load at each loading cycle and the initial maximum tensial load of a pin supported bar subjected to eccentrical load. 2) In the elastic-plastic region of the axial load displacement curves, the change of stiffness of a restrained bar was less than one of a pin supported bar having the same slenderness ratio as a restrained bar, especially, deterioration after the maximum compression load of a restrained bar at each loading cycle was less than one of a pin supported bar. 3) Under identical stiffness of restraining, spring, close agreement between analytical and experimental values of magnification a for load carrying capacity at the reversed points was obtained. 4) The effect of the eccentricity of axial load on the cyclic behavior of a restrained bar was very large in the elastic-plastic region of the axial load-displacement curves.

Periodically intermittent noises are sometimes designated as the major irritants of our society. The perceived magnitude of these sounds, however, cannot satisfactorily be evaluated by the established methods. Through two psycho-acoustical experiments described here the author tries to quantify the perceived noisiness of periodically intermittent sounds in comparison with that of steady sounds. In the first experiment eight trained subjects compared, by the paired camparison method, the noisiness of 25 patterns of intermittent sounds with that of steady sound. Several interesting findings were obtained by this experiment, which were organized in a proposal named the Perceived Noisiness Model of Periodically Intermittent Sound 75-A. In the second experiment 34 untrained subjects were used in a paired comparison experiment to validate the Model 75-A. The result was successful and the model was validated. Proposals and related discussions can be summarized as follows; 1) Consideration for the startle effect is indispensable to the proper evaluation of periodically intermittent sounds with impulsive nature. 2) Most of the established methods lead us to a considerable underestimation of these sounds. 3) The perceived noisiness of these sounds can be quantified by the cumulative contributions of the energy effect, the positive startle effect, and the negative startle effect.

This study reports the tendency found by the survey on housing life in the typical dwelling units. Results are as follows : (1) The greater part of the units is occupied with small families including wheelchair users. (2) In case of the household with wheelchair users, the DK is used very well. But in case of the handicapped such as the bedfast, as they are taking meals at their bedsides, the DK is used only by the other members. (3) Almost all the wheelchair user are sleeping in bed the Western style room. But in case of the bedfast the tendency using the Japanese style room is found. (4) The south side DK type is better than the north side one. It is because the former needs not to pass through a room adjacent to DK.

以上の分析をまとめて, その主要点をあげると, 1)前編の2章で仮定した都市化の需給基盤要因にみられる3側面-[集中・変動性], [階層性], [地域構造・地域機能]が第1成分(都市性)・第2成分(変動性)・第3成分(中心性)によって具体的に説明される。このことは逆に都市化の状況の説明変数として上記3成分の組合せが概ね妥当性をもつということができる。2)第1成分は「都市性」として, 人口の階層構造の主要な説明変数となり, 人口の市街地集積性および人口の移動性ともかかわりをもっ。さらにこれは続編5章で明らかにする住宅需給関係の社会化・多様化の要素も含んでおり, 総合的な意味解釈として「都市性」として理解できる。3)第2成分(変動性)は需要の変動性を説明し, 住宅需給関係における住みかえ移動の基盤を説明している。またこの成分は日常生活圏における地域間の(通勤などの)流動性をも説明している。4)第3成分(中心性)は都市の政治・経済的機能の中心性・日常生活圏における通勤流動にみられる中心性を意味し, 住宅需要発生の経済・社会的な背景と需給関係の地域構造的な側面の背景を説明している。5)従って, 都市性(FS1)と中心性(FS3)を主象軸に都市を基本的に分類し, 変動性(FS2)を説明変数として加味する前編3-3項の基本類型は, 住宅事情の都市類型を明らかにする上で意味をもとう。続編において, 住宅需給関係および居住水準の面からこの都市類型別の特徴をさらに明らかにしよう。

This report is based on the investigations of actual state of activities of social education, sports and recreation in farm areas, with a view to examination of the desirable conditions of these activities. The investigations are practiced in three farm areas, in summer. The results are summarized as follows : 1) Amount of activities (per 10000 paople number of activists perday) is largely found. 2) It is largely affected by sex distinction and age, especially peoele in their twenties have large quantity. 3) It is distinctly affected by thee types of occupations, especially people engaging in agriculture have small quantity. 4) It is distinctly affected by the agricultural conditions of each farm area. 5) It is not always in proportion to the number of activeists in all sort of activities. But it has been found possible to classify the activities into some categories by the correlating the values of the two.

慶長度後陽成院御所より延宝度二次の東福門院御所まで十四の院御所における殿舎構成と数寄屋風書院, 数寄屋風書院の平面と機能について考察した。その結果, 院御所における殿舎構成は基本的には広御所(対面所)-小御所-書院(休息所, 奥対面所)-常御殿であり, その内書院なる殿舎に数寄屋風書院の要素が現われる事がわかる。又これらの数寄屋風書院の平面について共通している事は, 主室に座敷飾が数多く設けられ, 室内意匠も延宝度二次東福門院御所の奥対面所に見られる様に華美だった事が予想される。しかし延宝度一次東福門院御所の休息所では座敷飾の自由な構成はもちろん, 土庇, 色付, 丸太柱, 平縁天井, 透し彫り欄間等すべての数寄屋風書院の要素が現われていた。この様な特徴をもつ院御所の数寄屋風書院では振舞を中心に, 時には道具拝観が行なわれていた。

This paper is one of a series of works in which I intend to clarify the carpenter's party by doing a research of it's history through doccuments left by a carpenter's family in Osaka. The bussiness circumstances of master carpenters and pupils will be discussed in this paper. The summary is as follows : The members of "Juban-muyori" which is one of a carpenters party in Osaka were varied 49-34 persons from 1843 to 1857, and there were many changes in them. The bussiness district of a carpenter were in Osaka, but not limitted in the district of "muyori" which he belonged to. Master carpenters and pupils were punished to stop his bussiness when they departed from their rules.
