This report are discussed for making manifactual Autoclaving board. The sample's proportion are defined by Calcium Index and they are within range 0.05〜1.60, and with the exception of Asbestos 15% constant. The result are follows. 1. Autoclave curing's temperature keeps 180℃ (10.2at) constant, curing time is 8〜20hr. Strength is calculated by law of square density. The max. of strength is within range of Calcium index 0.3〜0.6. Doromite is able to use for Autoclaving board, but are limited in MgO quantity. Gypsum is effective to mix about 2%, specialy to lime-silica-fly ash system. 2. Drying rate of Autoclave curing sample is later than Atomospher curing. This tendency is remerkable at Calcium index 0.7 and below. 3. When sample contain water below about 4% that become second zone of the folling-rate period, length change of Autoclave curing sample is generally larger than Atomospher curing. But over about 4%, the former is smoller than the latter.

This paper shows some examples of structural analysis for the two cases of the 8-strories building during the three kinds of earthquake motions by using electronic digital computer. From this result, we obtainned the conclusion as follows; (1) These building vibrate in their own first natural period and we have to notice the residual displacement in upper story of building of which the restoring force characteristics is of perfect plastic type and of which the damping factor is small. (2) The spring constant ratio in the elastic range and in the plastic range, and the damping factor for the building have influence on the structural response considerably. (3) From the examples of the structural response during the different kinds of earthquake motions, the earthquake motion which give the bad effect for building can not be simply determined. (4) The distribution of the yield shearing force coefficient should be taken to be smooth and this distribution have to be determined as concerned with the distribution of ductility factor.

In steel frame structures, it has been emphasized by Dr. Heki and Dr. Naka that shear deformation of the web in a connection greatly influences the stresses and deflections in the frames. This paper presents a slope deflection method for frames with connections having webs subject to deformation by shear force. It consists mainly of two parts, one refers to the derivation of the genereal equations and the other refers to the automatic analysis of them to which a digital computer can be applied in the next step.

The paper consider the approximate safty load factor of tall steel frames which are not braced against horizontal lateral loads. The basic tool used in the derivation of a possible analysis method is that of the plastic collapse and the buckling collapse according to Kuranishi's Theory. Kuranishi states that "formation of some number of yield hinges bring about two kinds of collapse. One of them is the plastic collapse, the load for which, however, is appreciably reduced. In other cases, the load becomes heigher than the pure buckling load considering the existing yield hinges, and the equilibrium falls in unstable state to cause a type of instability which is called here the buckling collapse. Thus, the load limit for these two kinds of collapse is in general much lower than the conventional limit for the plastic collapse and the buckling". He showed the interaction diagrams of single-bay portal frames accurately, in order to illustrate his thory. However, his general theorem are too complicated to apply in practice as he admited. Then, the present writer has calculated to show the practical result of interaction diagrams of standard tall steel frames as following assumptions. 1. We take up single-bay rectangular frames with story n, rigidity ratio k and the radio of fully plastic bending moments at beams to columns β=M_<p′>/M_p, where, k=(EI_b/l)/(EI_c/h), h : height of the columns, l : span of the beams, EI_c, EI_b : flexural rigidity of the columns and beams, respectively. 2. The horizontal lateral load H at each floors and axial load P at columns are constant. 3. The parameter of diagrams are Z^2=Ph^2/EI_c, Qh/M_p, where Q=nH/2, and the value of n and k are variable as follows. n=1, 2, 3, 4, 5, 10, 15, 20 k=0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 4. The approximate limit ofβto produce the first yield hinges at their feet is investigated. 5. The interaction curve of the plastic collapse is conveniently simplified by the line as to drow from the point of pure buckling on the buckling collapse to the point of conventional limit for the plastic collapse in straight line.

In the previous report, we have dealt with the general solution of crossed partial linear difference equation which was expressed in term of stress or deformation about spaced trussed plate having infinite lattice element with simply supported edges. Now, we shall proceed our discussion with the study made on to the solution for boundry condition with four pointed supports continuous in edges by the same method mentioned in the previous report. To begin with, the very same procedures can be applied for the solution of homogeneous difference equation and then inhomogeneous difference equation af referred to in the previous article, except that we must consider the conditions of horizontal deformation, for the equation is indefinite only in case of symmetric condition when calculating equation of stress and force.

There are several methods for analysing the local behavior of perpendicularly welded tubular joints whose test results were reported in Part 1, here, the application of theoretical solution of cylindrical shell concerned with similar problem and the approximate method assuming a ring with specific wide are investigated. The results of this study are compared with several present design techniques. As the result of these procedure it is shown that the local strength of chord member in perpendicularly profiled joint is given by below expressions approximately. P_max=(80α/π+2)σ_y・Z/R…(2.29) P_y=(60α/π+2)σ_y・Z/R…(2.30) where, α=sin^-1d/D radian Z=B_s・(T^2)/6, B_s=1.52R√<R/T> Above expressions are applicable to chord members which the ratio D/T, between outside diameter and the wall thickness, is within the limits of 15 to 40. Next, we investigate such a case that axial force of branch tube is tensile. Test results show that the load carrying capacity of joints with tensile branch is one and half of those with compressive branch. Although the maximum load is decided by fracture in the heat affected zone of weld, in this case it is also possible that the strength is expressed with the same parameter in the case of compressive branch. This fact implies that the strength of weld is affected by the stress concentration caused by local deformation of chord member.

This is the third report of the several series of investigations on the function of housing estate in human life. The purpose of the research is the same with the one mentioned in the first and second reports. This time, actual survey was done to the people in two groups living in 52 houses and 150 dwelling units in "slab type" flats at Furuichi-Estate, Osaka during November and December in 1962. Some of the results of the research are as follows : 1) Social contact in neighbourhood is dominant as for wives compared to her whole contacts, while it is not so as to husbands. 2) Much contact in neighbourhood is rather done in the private houses or dwelling units than in public facilities such as a meeting room, assembly-hall etc. 3) Most of the husbands attend the offices in their own city, e.g. Osaka in this case. 4) People do their daily shopping not only in the housing estate area but in the shopping street of the suroundings. But, they get extensive and hobby goods at the department store in the center of their city. 5) People spend the most of leisure time in their own private houses. In this meaning, the houses or dwelling units should also be designed for these leisure time. 6) People have, so to say, a feeling of "community" for the housing estate areas.

It is, by now, widely recognized that the population of newly developed community has quite unbalanced age structure. Of this subject, I have made survey on several communities and made clear on relation between age structure and the composition of family types, average size of dwellings, length of terms after the developement of the community. Results : 1. Age structure of a community is deeply influenced by length of terms after its developement, and as this terms become longer, the unbalance of age structure become not so serious. 2. Also, this unbalance of age structure is concerned with the average size of dwellings in the community, wken the size is small, this unbalance is remarkable. 3. When all households in the community are devided into 10 groups by family types, each group has fixed age structure, irrespective of the status of the community. So, When the composition of households by family types of the community is provided, we are able to estimate the age structure of the whole community. The difference in age structure between two communities is due to the difference of the composition of family types between them. 4. Only a few non-related household member are included in population of the new community. 5. Each group of households by family types has fixed distribution of household size. When the composition of family types of a community is provided, we are able to estimate the distribution of household size of the whole community.

Constructing a new town, it is basic to calculate future population of the region. In such case, as the number of houses are planned at each stages, population are known through households. The method of this article is below put the number of households are constant. Divide the type of household into n and the ratio of types at immigration (F) is constant. Varies year by year, and the natural variation (V from year t to t+&lrtri;t) is constant about households at any cities in Japan. Ratio (R) of the number of households emmigrated to the resident isconstant on each type of household. Knowing Fat year t, F at t+t is desided with R and V. From the household construction, the construction of another index of population such as age structure is decided. On age structure of a population is constant on each type of household (Z(F/A)). In this article we reported a case on planning a new town Kozozi, mother city of that is Nagoya-shi. To controle the population of a new town is important and we think it is possible by controling the number of houses to be constructed.

Zum Zweck des theoretischen Urteils uber Feuerwiederstandsfahigkeit von Bauteilen, mussen wir uns zunachst mit der Warmeubergangsanalysis, namlich mit der Aufklarung uber dem Zusammenchang zwishen Zeit und Temperatur im Innern der Bauteile unter Feuerangriff beschaftigen. Viele Forscher haben ein starkes Interesse gezeigt, an numerischen und graphischen Methoden zur Aufklarung uber dem Zusammenhang, so daβ interessante Beitrage in groβer Zahl vergeoffentlicht worden sind; von Schmidt, Emmons, Dussinberre, Ban, Harmathy, usw.. Trotzalledem kann kein Beitrag auf jede Bauteile ohne vereinfachte Annahme angewandt werden. Hier liegt der Grund; namlich umgebende Tempertur, Warmeubergangszahl, und die physikalischen und chemischen Eigenschaften der Materien verandern sich, auβerdem vielfaltige Formen von Bauteilen bringen den Warmeubergangsproblemen verschiedene Verwickelungen. Fundamentale Gleichungen, werden hier geschrieben, aus Warmegleichgewicht des Grundkorpers (vergl. 1 und 2) gefuhrt, und die konnen zutreffend auf numerischen und graphischen Methoden um eins, zwei, und drei Dimensionen in rechtwinkligen und walzenartigen Koordinaten angewnds werden. Die Gleichungen grunden die Aufnahme von Warmeeigenschaften der Materien auf die numerischen Methode, welche Harmathy um eins Dimension in rechtwinklige Koordinate veroffentlicht. Die Gleichungen, die wir dadurch fuhrten, konnen zur zahlenmaβigen Berechnung und grafischen Losung auf jeden Bauteilen ohne unpassend vereingefachte Annahme fuhren. Hier ist eine Fundamentale Forschung zu fuhren eine praktische Methode, d. h. eine neue graphische "Methode auf Grund von Ausgleichung", uber die wir, in kurzem berichten wollen.

Spending quantity of light, heat and water in each government office building is not same on the whole, but is has verious kinds of type according to the variety of form and degree of building equipment, form of business and density of the staff. And, it has been increasing constantly year by year in proportion to the progress of business environment and mechanical development of business method. Especially, spending quantity of electric power has been increasing remarkably. As for the seasonal variation, spending quantity of electric power shows the peak quantity both in summer and winter. Water quantity shows it in summer. Gas and coal quantity shows it in winter. Almost of the peaks of spending quantity of electric power in winter can be seen generally in old-fashioned government office buildings. But this kind of peak quantity has been changing from winter type to summer type year by year. As a rule, spending quantity of light, heat, and water in government office buildings changes in proportion to degree of business activity, with which it is related closely. And especially, such kind of a tendendy can be found conspicuously in the lapse of hours in a day.

This treatise deals with the documents between 1728 and 1902. Trese documents were written in building houses and storehouses, and they were recordes about the purchase of building-materials and the charge for labor of the artisans. In this district, former years, farmhouses were built by the peasants themselves without the assistance of professional workers. But, with the advance of architecture, high techniques were demanded gradually. And here, as a professional worker, the carpenter was appeared. And then appeared the thatcher and the sawyer as professional workers. (Both appeared the latter half of 18 century hence.) But it was rather late that plasterer takes his share in building the houses. It can be conjectured that the plasterer joined in building houses at the end of 19 century. On the other hand, these artisans above mentioned, were engaged in agriculture and made a living by them.
