In this paper, a composite beam subassemblage, which has an elastic-plastic-strain softening concrete slab, is analysed. And the following conclusions are obtained. 1) The behavior of strain at the top and bottom flange at the end of the beam is much effected by the difference of positive and negative moment carrying capacity of composite beam, while it is not much effected by vertical load on the beam and strain softening modulus of concrete slab. And, it is indicated that the relation between the total of end moment (ΣM) of composite beam and strain (ε) at the end of the beam can be predicted on the basis of M-φ relation of steel section. 2) A method of predicting required maximum strain ductility factor at the end of the beam of subassemblages is illustrated, whose strength ratio (β^^-) of composite beam to column is given.

A stochastic equivalent linearization technique of bi-linear hysteretic characteristics is developed. Using this technique, an ordinary differential equation for the estimation of the second order moments of a sigle-degree-of freedom bi-linear hysteretic system subjected to non-stationary random excitation is derived. A comparison of two techniques-an equivalent linearization and a Fokker-Planck equation techniques-are made concerning the differences of the two sets of the ordinary differential equation and the transient r. m. s. displacement and velocity responses given by these two techniques. Extention of this approach to a multi-degree-of-freedom bi-linear hysteretic system and a single-degree-of-freedom poly-linear hysteretic system is discussed.

In this paper a random response analysis method of hysteretic systems under nonstationary excitation, using Markov Chain Model, is discussed. Especially attention is focused on an applicability of this model to an amplitude-nonstationary excitation case. This probabilistic model assumes a position of response in a Force-Deflection plane to be a Markov process, and the hysteretic random response is estimated as nonstationary probability functions that are distributions of the response-position over a finite number of regions discretized in the Force-Deflection plane. According to this model, also the first excursion probability and nonstationary distributions of maximum response level can be obtained. This model has been applied to a SDOF elasto-plastic system to a nonstationary Gaussian white noise. The nonhomogeneous transition matrix, which governs an essential structure of the response, has been determined by a combination of a potential energy conservation law and a threshold crossing problem. The theoretical results have been compared with simulation results and both have showed good agreements. So it can be said that this model is applicable to an amplitude-nonstationary excitation case. We hope that this model will be extended to a nonwhite input excitation case.

The purpose of this paper is mainly to investigate the following two points of toroidal shell by numerical analyses. One is to investigate the validity of Donnell theory to the toroidal shell. For this purpose, the numerical results of some problems by means of Donnell theory are compared by other theories, that is, Sanders Koiter theory and Love theory. Another one is to investigate the influence upon the buckling loads of two types of pressure load, namely constant directinal pressure load and hydrostatic pressure load. The following results were obtained : (1) Geometric parameter a/b ratio is very important with respect to the behaviours of this shell, where "a" is a redius of cross section, and "b" is the distance between the center of cross section and the axis of revolution. (2) Buckling loads by Donnell theory are sometimes different from the values by other theories, so that when Donnell theory is adopted for the buckling analysis of this shell, we should pay attention to estimate the results. (3) Buckling loads of toroidal shell due to both constant directional pressure load and hydrostatic pressure load are always different.

Column bases embedded in base concrete have sufficient rigidities and strength when the embedded portion of the column is long enough to transmit the bending moment developed at the base of the column. A series of experiments was carried out on bases of steel columns with H-section shape bent about the strong axis of the cross section and the results were summarrized into an empirical formula which may predict the collapse mode and the ultimate bending moment capacity of the column base.

Analysis of shifting stress and deformation in reinforced concrete structures with crack extension requires the fracture criterion. So experiments on light weight concrete are performed with beams containing an edge crack under pure bending (Fig.3 and Photo.3) and rectangular plates containing a central crack under tension (Fig.2 and Photo.2) to examine that the crack extension will start when the stress intensity factor K_1 reaches to a critical value (tables 10, 11). Furthermore rectangular plates (150mm×300mm in size) with a centrally located and oriented crack under tension (with θ=30°and 60°in Fig.2) and rectangular plates (150mm×300mm in size) with a central crack under concentrated forces acting at internal points (Figs.4-6 and Photos.4, 5) are examined theoretically and experimentally. On examination, in order to obtain stress intensity factors for a central crack in a rectangular plate under concentrated forces acting at internal points, the body force method proposed by H. Nishitani is used (Table 9). For this purpose, the solution of the finite plate under concentrated forces acting at internal points is obtained by a polynomial mapping function. The hypothesis that the crack will start to grow in the direction of maximum tangential stress ((σ_θ) max.) when (σ_θ) max. reaches to a critical value seems to be verified by these experiments on light weight concrete (Tables 12, 13 and Fig.9).

The thermal sensation of human being (the subject) is influenced by a composition of the exterior space where he stands (Fig-1). We show factors of a composition of exterior space by its scale, layout of walls and cover, and Closed Ratio (C.R.), for example, H (1)-[3 NS]-C.R. (0.57). The scale is expressed by names of the models in Space Modular Co-ordination Chart. The layout of walls and cover is classified by number of closed face (1〜6) (Fig-2). The method of calculating C.R. is shown in Fig-3. We measure the thermal environments of exterior spaces (streets, open spaces, etc.) by S〜H (1) models in Space Modular Co-ordination Chart (100m×100m〜1km×1km : FIELD, 1m×1m〜10m×10m : UNIT). Next, to evaluate the thermal environments of exterior spaces, we measured air temperature, surface temperdtures of walls and grounds, wind velocity at exterior spaces of several types for 24 hours at intervals of one hour, in summer, at Takashimadaira (high-rise apartment houses area) and Sumida (high-dense residential area) in Tokyo (Fig-4). The composition of the exterior spaces are shown in Fig-5, 8. The data of the measurements are shown in the rest of graphs in Fig-6〜12, Table-1, 2. Fig-10 shows the distribution of surface temperature of exterior space by infrared photographs. We found that is slight distribution of air temperature in 1kmx 1km field (H (1) model), but that the differences of surface temperatures are very large because of difference of compositions of each exterior spaces. So, the factors of them (layout of walls and cover and trees, C.R., materials) are important for their thermal environments.

To catch hold of quantity of family dynamics, resident cards at Nishikata-cho on Bunkyo-ku, 1-chome Tsukishima on Chuo-ku are investigated, and some results are found. (1) Comparing two types of measuring way, R-type and Q-type with Census, total number of Non-single family is almost same in R-type and Census, but that of each family are different. The number of unique family type could be measured by comparing Q-type with Census, which, parents and childs family live in the same house but separated. (2) Each family type's change rate of a year is almost within 1/4-1/2 of that of three years. Then the series of unchanging rate on each year of each family type are measured, which based on more suitable concept for quantative analysis. (3) The rate of growth and extinction which is the flow devided by the stock is different according to the family types, but between two districts there is similarity in each family types (4) The rate of non-single family's transition within neighbor wards is higher than that of single family's.

The final goal of this study is to make a comparative investigation into the new home warranty systems in the world. The nations that execute at present the home warrnty system are as follows; France, UK, USA, Holland, Canada, Australia, Sweden and Japan. The aim of this paper is to investigate the old French system that is reformed by the law on the 4th January 1978. The main results obtained are as follows; In the old system, 1. the warranty is subject to the enforcement clause of the civil code, 2. the warranty is borne by architect, constructors, vendor of building and/or developer who have a lagal relation on a contract between the owner of building, 3. the duration of the warranty is 10 years for the structural damage and 2 years for the other defects, 4. the aim of warranty is to physically remedy defects of building, 5. the interest of warranty can be transferered to the successive possessor of building, 6. the quality of building is controled in accordance with NF, DTU and Avis Technigues, 7. the inspection by private organizations is necessary for the insurance, 8. the constructors are qualified by the semi-public organization named OPQCB, 9. the insurance is obligatory to the architect only, 10. the instrance covers generally all liability risks in construction of building. The main problems to which the reformation of the legal system to give a solution, are as follows; 1. Too long time for remedy; all disputes are put on trial and it took more than 8 years to settle them. The insurance did not operate before the settlement of the dispute. 2. Inefficiency of insurance; the insurance cost increased rapidly on accout of infration and propagation of damage during the legal process. 3. Irrationality of distinction of building elements between ten years warranty and two years one; the distinction is based on easiness of detachment of building elements. 4. Increase of defects; the inspection system did not function so effeciently that the failure ratio increased 15% par year.

This paper is one of a series of works in which we intend to clarify the process of establishment of Japanese architectural reference books in Edo-period. We can find thirteen documents of "Nihon-Banjyo-ki" type of architectural reference books. As a result of examining the differences of their composition and expression, we can classify them into four types (Type I-Type IV) and can think as follows; the original "Nihon-Banjyo-ki" seems to be the original one of these documents. Type II, Type III and Type IV come only from "Nihon-Banjyo-ki", but "Unjyo-ki" combines with "Nihon-Banjyo-ki" to make Type I.
