This paper reports the rerults of the test on the bending behaviour in the elastic field and on the ultimate strength of various cross-sectional shapes of panels. The formutae which determine stresses and deformations in elastic field for the two types of these panels are derived. The numerically calculated results of these formulae are compared with the results of the test and with the results calculated from the Dr. Tsuboi's formulae.

Estimation of the numerical errors on Fourier Transform method for a request of time series response of one dimensional wave function included viscoelastic term. This errors was guessed from the response of vibrational system of one degree of freedom. According to studies, especially important errors are discrete error and circulation error. 1) Discrete error This error is determined by relation of sampling ratio and natural period of system. Relative error is 0.28% in case that sampling time is one ten of natural period of system, and in case of one twenty, error is 0.034%. 2) Circulation error This phenomenon is that a part of free vibrational response of system turn to front of data. This quantity relate to natural period and damping factor of system, the more long of period and small of damping the more increasing of error. In case of multi-layerd structural ground, at the surface response to income wave, circulation error is most in comparison of other boundary response. But we can avoid this error by waste calculation about 15-20 seconds. When we assume viscosity in the layer, absolute value of circulation error decrease, but relative error not decrease because of whole amplitude too small. As above mentioned, practically, when we adopt that sampling time is 0.02 second and waste calculating time is 15-20 seconds, relative error is inner of 5%.

In a compound pendulum, which consists of ligid unit pendulums A_1, A_2, …, A_n, …, A_N, and three-demensional pins, B_0, B_1, …, B_n, …, B_<N-1>, unit pendulum A_n with center of gravity D_n and mass m_n supports A_<n+1> on pin B_n, and is supported by A_<n-1> on B_<n-1> and A_1 is supported by the foundation on B_0. Point E_n is defined on the straight line B_n-D_n, by m_n : Σ^^N___<i=n>m_<i>=(length B_n-E_n) : (length B_n-D_n). Plane π_n is perpendicular to the straight line B_n-B_<n-1> and intersect B_<n-1>. If D_n and E_n exist at the opposite side of π_n to B_n in every A_n, every B_n takes higher position than B_<n-1> in stable equilibrum. In this paper, such a compound pendulum is named Tower Pendulum. If B_n, B_<n-1> and D_n exist on a straight line in every A_n, every B_n and B_<n-1> take position on a vertical perpendicular line in stable equilibrum. In the stable equilibrum, B_n and B_<n-1> could be changed to pins which have axes intersecting the center points of the former three-dementional pins. In the free vibration of this system, if the natural vibration are defined as 1st, 2nd, …, j-th, …, N-th degree, degree, from vibration of the longest natural period to that of the shortest, the number of changes of signs in the j-th natural mode {_ju} is N-j. In the forced vibration of the system caused by ground acceleration, denoting β_j as modal participation factor, about particitation vectors, [numerical formula] Displacements, velocities, and shearing coefficients of every parts of the Tower Pendulum, caused by earthquake ground motion and wind force which vary with the lapse of time, can be calculated using those of one mass point system.

In this paper, continuously part I, we attempt the application to the concretely represented shells with our general nonlinear theories which were constucted and developed at part I. The rigorous fundamental equations and those approximated ones for shallow shells (especially with surfaces of the second order), cylindrical spherical, conical and torus shells are derived in section 2, 3, 4 and 6, respectively. The resulting equilibrium equations for cylindrical and spherical are carefully compared with Love-Timoshenko's equations and examined those in detail. The appropriate constitutive equations are showed in each section. The lowest order shell equations, which are the simplest approximate nonlinear fundamental equations, are formulated for each shells by the reason that they play an important part in nonlinear analysis.

In previous paper, it was shown that J_<IC> fracture criterion was able to estimate the fracture in both linear and non linear regions. And it was comfirmed that J-value was calculated by the finite element method. In this paper, we apply J_<IC> fracture criterion to the fracture of Tee Connection modeled Steel Structure Beamto-Column Connection. When we apply non linear fracture mechanics, we confuse that a crack is very short. A crack of the steel structure is generaly very short, but J-integral is defined with the deep notch. So we investigate that the crack length have an effect on J-integral, and apply J_<IC> fracture criterion to Tee welded joints. The results are shown as follows.(1) A condition of a crack initiation changes with stress conditions. And tbe condition of a crack initiation by J_<IC> fracture criterion is equal to the condition of it by a strain. (2) J-values of crack initiation becomes small in proportion to a multi-strees-condition, and approach a critical J_<IC>-value. This J_<IC> fracture criterion can be applyed to the steel frame constructions.

If the waste heat recovery and its utilization is realized, we can raise the thermal environment in urban area. It is said that utilization of waste heat of Refuse Incinerating Plant (R. I. P.) is good chance of realization. Though R. I. P. is large source of heat exhaust, it is diffcult to estimate the quantity of heat exhaust. As the heat source of R. I. P. is refuse, we can't infer the heat quantity from the quantity of energy consumption. In this report we put an investigation into R. I. P. in the whole country, and analize the result statistically. In the result we found the index of heat exhaust, heat recovery, heat utilization (possibility) in the form of Q=aR (Q : quantity of heat <Gcal>, R : quantity of refuse incinerating <t>, a : constant). Main indexes of heat are as follows. 1. Q_e=1.529R (Q_e : quantity of heat exhaust) 2. Q_r=0.981R (Q_r : quantity of heat recovery) 3. Q_u=0.787R (Q_u : quantity of heat utilization) In this case R. I. P. haven't independent power system that use the waste heat. We compare the quantity of heat recovery used of the index with the practice measurement value based on the investigation. In this study the coeffcient of correlation came to 0.9540, we found that we could use the index in a high rate of preciseness.

The convex mirrors which are attached to a photographing device and reflect the incident rays in parallel with their axes to give the images of various projection forms have been studied. In the process of the determination of their generating lines, the authors have found that those images are theoretically limited to the Stereographic Projection Form, and the images closely similar to the Equi-Solid Angle Projection Form, the Orthographic Projection Form and the Equi-Distance Projection Form can be made by the suitable convex mirrors which reflect the rays in parallel with their axes. After strict inspections of the relative errors about the images of closely similar projection forms above mentioned, the authors have been convinced that the images of the convex mirrors are useful for the practical purposes, and they are trying to complete a photographing device with the four types of convex mirrors.

In our earlier paper (1), the necessity and method of analysis on the planning process of social facility and some results were shown. The aim of this paper is to analyze on the information system in the planning process and to clssify the facilities according to the similarity of information processing. The information flow and density in each planning process is constructed through putting in order to the official documents and informations as figure 3-1. The information density is increasing with processing of planning, the third planning cycle, where the cycle composed of a series [PLAN]→[DO]→[SEE] was shown in earlier paper, is disturbed by a great deal of information processing. A co-ordinating system, communicating with the externals and processing information, is needed in planning section. In order to analyze the information network of planning process, some following coefficients are defined : 1) I_<WR(ij)>=a_<ij>/a_<ii> (Information Wrap Ratio), 2) A_i=1/nΣ^^n___<j=1>I_<WR(ij)>, 3) B_i=1/nΣ^^n___<j=1>I_<WR(ij)>, 4) C_i=A_i/B_i, 5) D_i=√<A_i×B_i> and 6) Y_<ij>={a_<ij>d_<ij>-b_<ij>c_<ij>}/{a_<ij>d_<ij>+b_<ij>c_<ij>} (Yule coefficient) where a_<ij<, b_<ij<, c_<ij< and d_<ij< are frequence of information concerned with i-th and j-th facilities, i-th and not j-th, j-th and not i-th, and neither i-th nor j-th facilities. According to the analyses with the above coefficients, the main facilities in planning process are kindergarten, shops, primary scool and clinic, the other hand assembly room for habitant and parking area are depended on the main facilities. It is need to re-examine the planning of facilities such an assembly room from a viewpoint of possibility for community.

This report is shown what housing needs the households with the disabled have and what guides are planned to satisfy those needs, according to the transfer ability and the households patterns. At last, we consider which house plan type is suitable to them. (1) Their housing life is influenced so harder that the transfer ability levels down. (2) Because DK is too small and narrow and they are not willing to transfer with accordance to their ability level down, using DK is not so much in spite of almost small house type 2 DK. (3) Using DK for eating is concerned with whether they separate dinning space form sleeping sapce or do not. Not separating cases increase in <WI>-<B>. (4) The transfer ability is referent from selecting the sleeping room for the disabled. It is shown a tendency to use main room in <A>・<S> and sub room in <WI>-<B>. (5) The disabled's working state is different from the house hold patterns. The ratio of working in their own house is so high in <A>-<WD>. (6) The tendency of using sub room as working room is shown so obviously that some basic daily life acts is concentrated upon main room, and using as one room is accelerated.

Oji and Koji which had once formed strict structure of ancient Heiankyo were deformed in their physical features as well as in characters especially by invation of many land lords. This resulted the disappearance of difference between Oji and Koji, and new urban space "Machi" mainly consist of street architectures "Machiya" was being established, enclosing rather narrow streets. "Zushi", the special name in Kyoto for the alley in a blook, is also discussed here, in its form and characters.
