It is primary object of this investigation to get data to establish design formulas of surrounding frame of reinforced conbrete walls after cracking. Experiments on six reinforced mortal walls of which wall panel has three kind of reinforcing ratio, 0.35, 0.70 and 1.05 percent were made under pure shear. Considering the results of the experiments, the author proposed the analysis method replacing the cracked wall panels with compressive and tension bracings to get the force of surrounding frame of reinforced concrete walls after cracking. Computed results coincide fairly well with tested restults until the maximum load. The resisting mechanism of reinforced concrete walls and the effects of reinforcing of wall panels are well clarified.

Through the investigation of the random response of single-degree-of-freedom systems having five various restoring force characteristics subjected to the stationary white noises, the mathematical expressions of the expectation λ^^- and of the standard deviation σ_λ of the nondimensional accumulated plastic deformation λ have been derived. In addition, the nondimensional root mean square velocities and the equivalent damping ratios have been evaluated. λ^^- is proportional to the product of nondimensional input intensity ξ and nondimensional time τ, and σ is approximately in proportion to ξ√<τ>. The proportional constants are peculiar to therestoring force characteristics. The coefficient of variation of λ is the least for the bilinear hysteresis, and increases in the order of the moderate slip, pure slip, origin oriented and progressive slip restoring force characteristics. The reliability function R(λ) which is defined prescribing λ as an index of the safety has been estimated using λ^^- and σ_λ. R(λ) monotonously decreases with increasing ξ/λ and τ. R(λ) is the greatest for the bilinear hysteresis, and decreases in the order of the moderate slip, pure slip and origin oriented characteristics. R(λ) for the progressive slip hysteresis is in a defferent fashion from the others.

In the Miyagiken-oki Earthquakes of February 20 and June 12, 1978, strong motion accelerograms were observed at neighboring three buildings (J.N.R., SUMITOMO-SEIMEI, 77 BANK) in Sendai City. These building are located within radius 300m (see Fig.1), and have almost same soil conditions composed of hard rock (see Fig.2). Seismographs installed in the basement floors of these buildings are set to almost N-S, and E-W direction, and therefore these records can be directly compared in each direction. These records were observed in different types of buildings, consequently in order to eliminate the influence of buildings and to determine the free-surface motions, each building was idealized as a mass-spring mathematical model, in which the spring-dashpot system for the foundation was assumed based on Ground Compliance Theory (refer to literature 6). As a result of this analysis, it was proved that the whole characteristics of acceleration time histories and acceleration response spectra at the basements and the free surface were slightly changed. The characteristics of free surface motions at three points were studied. Maximum velocities obtained by numerical integration were proved to be of the smaller dispersion at three points than the maximum accelerations, so authors paid much attention to velocity time histories, and compared the wave characteris tcs, horizontal orbits, and its cross-correlations. Finally, in both earthquakes, the authors found fairly good similarity of velocity time histories at the neighboring three points.

We are studying the methodology of design for our physical environment to save human energy expenditure and to perform household duties safely, but yet have not found the research which shows most suitable design for us in quantity about household-storage facilities. In order to determine the energy metabolism of human body accurately, we have selected a new apparatus to measure the volume and the concentration of human respiration continuously and automatically, which contains the recording system with the Wright Respirometre and the Expired Gas Analyzer, and contains the computer system to multiply volume by concentration about human respiration and to integrate them for a given time. At first, we have experimented on the reliability of this apparatus, and come to the conclusion that this apparatus satisfies our need generally to research the energy metabolism of human body. Next, the general plan and procedures of oxperiment with this apparatus have been determined as follows, 1) subjects are four young and sound females, whose physical characteristics are shown in Table 1 as similar to the standard of Japanese female, 2) height of open shelves is selected according to each elemental height of subjects (see Table 2), 3) utensils to be stored are box shaped object, which weight is 0.5kg, 1.0kg, 2.0kg or 3.0kg, 4) working motions are given while one or two hands as to place utensil on each shelf from the standard working board, 85cm in height and then to place back it on the board from the shelf and repeated in constant velocity as 10 times per a minute, 5) each posture of motion is choised by each subject in free, 6) procedures of measurement for human energy metabolism are shown at (6), 1, Section 3 as specific methods for using this apparatus. Essential results of this report are as follows : 1. Human energy expenditures for storing utensils on shelves by each subject are shown in quantity more accurately than in any other reports, under variant conditions about height of shelves, load of utensils and working motion with one hand and two hands (see Fig.8-13 and Table 3). 2. Experimental formulas of human energy expenditure for that work are shown as formula (8), (9) and (10), to generalize results of 1. and to apply those for working motion under given conditions. 3. As results of analysis on gained data, we are able to show the standard model of human energy expenditures for storing utensils on shelves by the standard Japanese female (see Table 7 and Fig.14).

The purpose of this paper is to study some problems of sun shadow arisen from the new structure and compare the sunshine obstructing structures handled by the Sunshadow Problem Adjustment Committee of Fukuoka City with another medium and highrise structures. The locations which problems have been arisen, are largely in places where numerous medium and highrise structures are erected, and the territories in which low structures have numerously been erected recently. As for the ratio of building volume to lot, many structures which occurred problems shows 200% ratio or more. Moreover, the total floor area and height of the building (or number of stories) are larger than the volume of other medium and highrise structures in the adjoining district. We reach the conclusion that Problems have been arisen from the difference of size of the new structure which inhabitations expect to the actual size, and fromthe volume of sun shadow. Strictly speaking, problems occur from the following cases. (1) The highrise building has been erected in a district where has not so many medium and highrise structures. (2) The size of the new structure (total floor area, height (largely exceeds the existing structures. (3) Housing is damaged by sun shadow. (4) The permissible limit is exceeded by (1), (2) and (3).

Though the ultimate purpose of this study is to analize variations of shopping districts and big shops according to operating the model of behaviour choosing zones, in this paper the system of model for analizing variations is designed. Conclusion : (1) The basic formula of the model ^kP_<ij> of the force which attracts the inhabitations of i-district at j-shopping district becomes great in inverse proportion to the distance from i-district to j-shopping district (resistant index : x_<ij>), and in proportion to the degree of charm (the index of absorption force; the areas of salerooms classified by goods : S_j, the total areas of salerooms in shopping districts : A_j, the number of places for pleasure : R_j, variations of shopping districts or big shops : V_j). From the standpoint of this view, the basic formula of the model adopts hypothesis such as the gravity-model. The basic formula of the model including these five indeves is as follows. [numerical formula] β_1〜β_5 : presumed parameters (2) The model of behaviour choosing purchasing zones, using the basic formula of the model is divided into four subsystems classified by traffic means utilizing for shopping. And the purchasing behaviour is forecasted in each part of the subsystems. As a result of trying to simulate the present situation with this model, analysis was proceeded with (P_<ij>×the coefficient of utilization classified by the traffic means) instead of P_<ij>, so the model came to have considerable application to the purchasing analysis.

In this paper we grasped how the dwelling of low level which is the drive of the voluntary change of residence, occurred from the view of the commuting time, the residence density, the eqipments, the rate of housing expenses and the sunshine duration. Then, we made it clear how each type of low level dwelling caused or deterred the change of residence connecting what sort of factors. Conclusion 1) Low level dwelling appears largely in non-public rental houses. We can classify the relations of the housing types and appearance of low level dwelling into three types. a) complex low level dwelling of the rate of housing expenses and the sunshine duration………condominum, non-wooden rental houses. b) low level dwelling of the residence density………public houses, issued houses. c) complex low level dwelling of the residence density, the rate of housing expenses and the sunshine duration (plus the eqipments)………detached rental houses, wooden rental houses. 2) Generally, the low level dwelling forms the pressure which motivates a change of residence. But the appearance differs in index of low level dwelling and in factors connecting with low level dwelling. a) In case of the commuting time, the pressure on change of residence acts similarly on plus side. But there is a tendancy to settle without improvement of the level of dwelling, in the specific house-hold types that have low rate of the change of residence. b) In case of the residence density, the pressure cannot act on plus and minus sides in thirties, C_k. It acts on plus side as wedge around this age group. Generally, the factors concerned with household connect with the change of residence, but other factors do not connect. c) In case of the eqipments, the pressure acts similary on plus side on various factors. d) In case of the rate of housing expenses, the pressure acts generally on side of stagnation or settlment without improvement, variing from other types, about the change of residence. But the quantity of this action is not large. e) In case of the sunshine duration, the pressure acts generally on side of the acceleration of the change of residece.

The aim of the study is to clarify the physical aspects of flashover of compartment fire and deduce an evaluation method on flashover with reference to the mathematical modeling of fire. In this paper, the flashover criterion of zero order reaction system is regarded as the critical condition on the existence of a steady state solution of the governing equations of fire which are abstractly represented by V_idT_i/dt=H_i, i=1, 2, …, n, where n is the number of zones. The mathematical structure of H_i is studied from such a point of view, and some methods to obtain the critical conditions of flashover are proposed. The main results of this paper are as follows. 1. The thermal state of the steady state solution of V_idT_i/dt=H_i under the critical set of parameters on flashover satisfies |∂(H_1, H_2, …, H_n)/∂(T_1, T_2, …, T_n) |=0. All critical sets of parameters can be obtained by mapping the critical hyperplane |∂(H_1, H_2, …, H_n) /∂(T_1, T_2, …, T_n) |=0 from (T_1, T_2, …, T_n) space to the parameter space by H_i=0, i=1, 2, …, n. 2. The critical value of a parameter on flashover under the fixed values of the other parameters others can be obtained by calculat ing its extremum under the constraint conditions H_i=0. Mathematical optimization techniques are available to this procedure. The above results denote that the critical conditions on flashover can be directly obtained without solving the governing equations numerically. The application results to a simple model with 2 zones assure the adequancy of the above results.

The free vibration analysis of fixed offshore cylindrical shell structures partially or totally submerged in water is studied by three different numerical methods, Rayleigh-Ritz method, finite element method and matrix progression method, in the consideration of the dynamic interaction between shell walls and water. In order to obtain the free vibration data which is necessary in the dynamic response analyses to wave or earthquake loadings, some numerical calculations are carried out by using these three methods. The modal characteristics of an offshore shell submerged in water are very sensitive to shell configurations and water depths. The natural frequencies decrease monotonically with the increase of water depth and the mode shapes for both displacements and stress resultants are different from those in air, because of the hydrodynamic inertia force due to an interaction with surrounding water. Also, the variation of modal characteristscs are influenced by shell dimensions, such as radius, length and thickness. Hence, it is important to discuss the free vibration data before starting the dynamic response analysis.
