Visco-elastic behavior of a roofing felt for constructing built-up roof membranes was investigated in this paper. Tensile tests of a roofing felt were carried out at very slow strain rates at temperatures in the probable conditions. The observed behavior was analysed applying Maxwell model, three elements model, four elements model and power rule. The properties of elements and material constants were expressed as functions of temperature, then the validity of these manners were discussed by comparison of the observed and calculated stress-strain curves.

The purpose of this paper is to cleary define the setting condition of cement mortar by distinguish the physical cohesion of the dispersed particles and the set of the cement hydrates. For that, through the primary setting process, we measured the resistancies met by a sphere in motion in mortar under the various viblated conditon, and caluculated the dynamic characteristics. Results are as follows. 1) It can be estimated approximately the setting process of cement mortar in the dormant period by the bimolecular reaction theory. 2) According as the hydration of cement become actively, the setting process of cement mortar has been distant from the theory. We suggest the time for inital setting time of cement mortar when the dynamic characteristics distant from the theory first.

Inelastic behaviors of a hollow circular section and a H-shaped section under constant axial force are investigated in terms of the transformations of the yield surfaces presented by the parameters P/P_y, M_x/M_px and M_y/M_py, where P_y, M_px and M_py are the yield axial force and the plastic moments about the principal axes under the monotonic uniaxial loading respectively. Characteristics of the subsequent yield surfaces for three values of constant axial thrust are discussed. The preloading paths adopted here are three types of that for each section, and the influence of cyclic loading of the bending moments are examined also.

In order to exactly evaluate the complex behavior of compound structures constructed from many sub-structures, such as nuclear reactors, the following considerations will be important : treating them as ground-structure coupling systems; analyzing by 3-dimensional FEM; and evaluating the properties of each sub-structure. We have used the Component Mode Method as the method which aimed at the efficient modal analysis of the total system by evaluating the properties of and the coupling relations between sub-structures. By rearranging the theory of the Component Mode Method as the process of the coordinate transformation of an equation of vibration, and from the numerical solutions, the following results are obtained : The transformation matrix T=RΦ summarizes the whole process of component structure analysis, where matrix R indicates both direct and indirect coupling relations between components caused by their stiffnesses, while Φ corresponds to those caused by the masses. Besides, R shows the effects of the components to be connected, and Φis affected by those already connected. Consequently, the generalyzed mass matrix M^*, obtained by the congruence transformation of mass matrix M by T, shows the coupling relations between the components' modes. This is confirmed by the numerical solution of a 3-dimensional frame model. If the degree of freedom is not reduced when analyzing each component structure, the results obtained from the eigen value analysis coincide with those obtained from directly analyzing the total system. This is confirmed by the numerical solution of a plane frame model.

The general formulations presented in Part 1 of this paper are applied to some boundary value problems of structural mechanics. The bending problems of an elastic beam with the Bernoulli-Euler assumption are selected as the fundamental ones and are analyzed numerically. The numerical results are illustrated by the linear bending of beam with the four cases on boundary conditions and the nonlinear deflection of horizontal cantilever subjected to a vertical point load or a uniformly distributed load. The results are compared with exact ones for linear ceses and Ritz's solutions for nonlinear cases, respectively. It is shown that our integral equation approach, especially a canonical formulation, produces the better results by means of fundamental solutions with a comparatively simple structure. Although the problems treated in this paper are restricted to a beam theory governed by an ordinary differential equation, our approach is also applicable to shell problems governed by a system of partial differential equations as previously reported in an another paper.

The purpose of this paper is to evaluate the safety margin of the reinforced concrete cylindrical shell on a layered rock ground to the intensity earthquake motion. The first step of evaluation is to compute the theoretical DGC for the model of a elastic five-layered medium due to oscillator tests and to transform into the rational function. The second step of evaluation is experimentally to obtain the elastic stiffness and the restoring force characteristics (reversed slip type) of the reinforced concrete cylindrical shell and transform into the theoretical model. The third step of evaluation is to make the elastic plastic analysis for the reinforced concrete cylindrical shell considering the DGC on a five-layered medum.

The purpose of this study is to suggest the method which can arrange and divide between "a service for neighborhood residents" and "a service for varioususers" about the use of the open school ground to the public. The results are as follows. on this second paper, we analyzed the efficiency of double line management method. 1. Double line management method which is combined independent method with concentrate method is able to satisfy and arrange "community use" and "extensive use" being caused by the following. The occurrence causes of extensive use are as follows; 1) existence of uncommunity groups, particularly spontanious groups. 2) the maldistribution of occupational groups in central area of city. 3) condition of each school facilities is unequal. Particularly, ground area is unequal. 4) the higher requirement of play. 5) impartial service in case of a few open school. 2. The other side, partinent disposition system of open school is able to enhance efficiency of double line management method. It is double disposition system with is conbined equal disposition system for community use with select disposition system for extensive use. 3. Select disposition is mainly necessary for occupational-baseball groups. Therefore, it is desirable that dispose open school about central area in city. Because occupational-baseball groups are distributed in its area. But it is impossible that dispose the selected open school in its area, for wide school grounds are very few in its area. However, wide school grounds are distributed in the near outer side of its area. So, it is possible that dispose the selected open school in this area. 4. The following is rather desirable than Double line management method, to satisfy utilization from non-open school districts in case of few open school in the city. It is independent management method in the zone unit which is combined open school districts with non-open school districts.

This study aims to account for the existence of sign system in the habitation space through the analyzing of variable room names. Those data were collected from 124 houses that were sampled from a housing area in the suburb of Hiroshima city. Process of analysis and results are as follows; (1) Before starting the analysis, the author summarizes about the sign-signification of habitation space and proposes the possibility of signification on both sides of denotation (as functions) and connotation (as values). (2) Based on the list of private room names, the exprssing way of 'individuality' is investigated. The author shows that the function of private rooms is vague and that the signification by private room names depends on the formality of the variation of room names and the connotation. (3) Based on the list of public room names, the expressing way of 'public property' is investigated. The author shows that public room can be expressed as the set of ll functions and proves denotation and connotation by mutual relation of functions. (4) As a result of above study, the author shows the shows the syntax of plan and the paradigms of room name variants and so comes to the conclusion that they are a sign system.

The purpose of this study is to show that architecture of Le Corbusier can be interpretated by means of a formal system. This formal system based on the set of rectangulars with certain ratios named "basic rectangulars", defines certain rules of articulation of them, i.e. "f", "g", "h" (defined in this paper), which are defined as notomappings, and the relationships between them. In part I the formal system is set up and several correspondences between the formal system and architecture are defined. And then Maison Domino and Maison Chitrohan are analyzed by means of the formal system. As a result, it is verified that the formal system has validity for interpretation on them.

A practical method to calculate some properties for the evaluation of flashover, such as the criterion on or the temperature at its occurrence, from Control Volume mathematical models of fire is derived based upon the characterization of flashover by thermal instability. The method is based on the mathematical optimization to estimate the extremum of an objective function, but it is emphasized that this should be done without calculating the differentials of the basic equations of fire, because mathematical fire models are being developed to be too complicated for analytical operations to be applicable. The report shows, by using a simple model to which analytical treatments are applicable, that the combination of the augmented Lagrangian function method and Hooke-Jeeves algorithm for direct search is appropriate for this purpose, and it studies some problems to improve the precision of the estimation. The established method was applied to the Quintiere et al's quasi-steady model which is too complicated for analytical treatments to be applicable.

The behavior of sealed joints in moving joint apparatuses in outdoor were investigated on polysulfide and silicone sealants. The test apparatuses were made up so as to induce similar joint movements to those in actual buildings, and the devices for measuring the joint movements and the stresses of sealants were also developed. They were exposed on the rooftop of the seven stories building in Yokohama, Japan at five positions facing to the east, south, west and north vertically, and horizontally to the zenith. The measurements were carried out for two years. The behavior of the sealed joints observed, that is, the amplitude and the rate of movements, the extent of joints at maximum and minimum width, and the stresses of sealants, are described and the effects of orientation or angles facing to, the seasons and the properties of sealants to the behavior of sealed joints are discussed.

In many historical cities there are old residential districts mainly in the centre. Those residential districts are composed by housing lots having narrow frontage and long depth. I have proposed the co-operative house rebuilding (C.H.R.) as one of rehabilitation methods for revitalizing these historical residential districts. In this paper I study on possibility to use C.H.R. as one of rehabilitation methods for historical urban residential districts in Kanazawa City. Methodology of analysis are cross sectional tabulation, multivariate analysis and lot mapping data. Main findings of this study is as follows, 1. Joining attitude household is one for seven and is mainly influenced by factors indicating lower housing conditions, higer land use intensity, awareness of rebuilding necessity and others. 2. Reasons for joining are "land use effectiveness", "economy" and "contribution to improve district as a whole", on the other hand reasons for un-joining are "having no necessity of rebuilding" or "being not able to retain the maximum freedom". 3. Possibility of C.H.R. is from 7% to 17% of lots and the mean lot size of C.H.R. is from 2.0 to 3.0 lots at each district according lot mapping data using factors indicating old houses built 35 years ago and more and awareness of necessity of house rebuiling.
