For determining the aggregate strength, the author proposes a new method, in which the aggregate is reduced to one half in volume and embedded in fine sand (0.1〜0.3mm) one layer after another, instead of being packed alone in test cylinder as in British Standard 812. The condition of aggregate thus produced is supposed to be more analogous to the one in concrete than in B.S. 812. It was found that there was a linear relation between the compressive load and the crushing rate of expanded-shale aggregate when they were plotted on log-scale co-ordinates. The discussion of the test result shows that the revised method has advantage in deciding the individual strength of aggregate, which is different with its size and that the smaller is the particle, the greater is the strength of it.

The purpose of this paper is to analyze the quality of the load which is acted on the gymnasium floor by athletes and to find the reason of perceiving the resiliency. The main results as obtained from the experiment are as follows : 1) The maximum vertical load is constant despite the rigidity of the floor. 2) The velocity of the load is large in proportion to the rigidity of the floor. 3) In proportion to the rigidity of floor, athletes must absorb large energy in short time.

The earthquake intensity to structure should be evaluated in consideration of the frequency characteristics of earthquake motions, the effect of plastic deformation of structure and so on. So a scale which is determined uniquely for the earthquake ground motions should not be used for the evaluation of earthquake intensity to all structures, but simple scale may be useful from the point of view of structural engineering if the scale is used in the reasonable application range. In this paper, maximum acceleration, maximum velocity and maximum displacement of earthquake ground motions, which are determined by filtering the long period components of earthquake ground motions because of their little effect to structure, are used as a scale of earthquake intensity, and their reasonable application range are shown based on the correlation coefficient between the non-linear response of one mass system due to earthquake motions and the maximum amplitude of them. As a conclusion, the characteristics of structure should be considered largely with respect to its stiffness when maximum amplitude of earthquake ground motions are used as a scale of earthquake intensity to structure. That is, maximum acceleration may be used as a scale for the evaluation of earthquake intensity to the structure of shorter period than 0.3 seconds, maximum velocity is for the structure of the period from 0.3 seconds to 1 second and maximum displacement is for longer period than 1 second.

This paper deals with the extension of the method, which was proposed by TOMIZAWA in part (1) and (2) of the same titled previous paper, for analyzing a cubic rectangular rigid frame in consideration of axial distortion of columns. The characteristic of this method i.e., to be able to calcurate the stresses of multistoried rigid frame by this method in less executing time than by the stiffness matrix method, is kept completely in this extension.

In the previous paper, the author reported the theory of the Chain Construction with Elastic Joints from the result of the experimental study on the Sandwich Curtain Wall. In the classical theory of the rigid frame, a joint and a member of the framework are considered as a point and a line severally. Namely the area of the joint is taken no account of. But the idealization is doubtful for the actual frame, especially for those of the wide flange members or of the lattice members. The joint must be regarded as a structural member which may be deformed as well as a beam or a column. The present paper shows that each of the structural members connected to a joint of the framework, rotates about the joint in proportion to the bending moment acting on the end of the members and the rotation may be caused by the shear deformation of the joint panel. It is assumed that bending deformation of the panel is disregarded and the panel part in joint is enclosed with rigid members whose ends are hinged. The idealized model of the frametwork is defined as follows, each of those members centered at a point each other with torsional member. The result could be applied for practical purposes because the values solved by this theory in several cases are guite appropriate for the other results.

In this paper some problems about the analytic estimations for movements of a pile foundation are discussed, and a new analytical procedure is presented. A model law for the relation between interaction shear stress and displacementat as the pile circumference is introduced, which shapes a parabola. Another model law at the pile tip is that axial stress and settlement are to develope in a constant ratio called tip-displacement factor. Suitable steps for analysis are presented with the series of equations, in which a pile is divided into several segments to simplify the calculations. The shear strength between pile and soil, tip-displacement factor, and a special tip-displacement value, at which shear stress reaches its strength at full length of the pile, must be determined to be used in the procedure of analysis. A numerical example is given, in which steps of calculation are presented in Table 1 and 2, and the results are shown. Although this analytical procedure will be useful in engineering practice to predict the movements of pile foundations, the constants and initial values for the equations must be determined considerately before performing calculations, because it must be noted that the informations obtained by only analytical methodes without any loading test will not always agree with that of actual foundations in natural soil.

Our purpose was to establish a standard by which the number of elevators in office fuildings could be estimated. We selected for study about a hundred office buildings constructed during the past several years in Japan and investigated the situation of elevators. The results obtained are as follows; There is a : 1. Relationship between the number of elevators and the total floor area. 2. Relationship between the rate of the number of freight elevators for the number of total elevators and the total floor area. 3. Relationship between the number of elevators per 1, 000m^2 and the total floor area. 4. Relationship between the number of stories and the number of elevators per 1, 000m^2.

Sixty-one sheets of plans of the Ueno Museum is preserved in the Tokyo National Museum. These plans was drawed by J. Conder and five students of the Imperial College of Engineering and the engineers of the Department of Public Works since August 1878 to October 1879. The Ueno Museum was two-storied brick building and had twenty-five exhibition rooms arranged functionally. It's total floar space was 49170 square meter and was largest at that time in Japan. It's exterior ornament was introduced the motif of Indian or Saracenic architecture for impart an Eastern character to it and J. Conder called it a pseudo-Saracenic style.
