The author reports on the compreseive strength of concrete with particular reference on size and quantity of artificial lightweight aggregate. Several series of tests are carried out using one size aggregate which are in narrow range of size. The concretes had shown breaking of aggregate particle before the maximum stress were reached, as well as bond failure in the interface. In this point expanded shale aggregate concretes are different from river gravel concrete. It is shown, however, that the larger is the particle and the more aggregate is contained in concrete, the weaker is the concrete. This means that the strength of one size aggregate concrete is expressed as a plane in a space co-ordinates with the strength and aggregate size and quantity as its axis, as in gravel concrete. It is therefore possible to presents an interpretation that the ordinary (mixed size aggregate) concrete has its own strength composition according to the volume and the size of artificial light weight aggregate.

The damages of many reinforced concrete buildings at 1968 Tokachioki Earthquake suggested that the rigidities, the strength and the failing behaviour were greatly influenced by the spandrel or wing walls in the frames. However, the influences of these walls on the structural characteristics have never considered into the structural frame analysis and the proportioning of the members, since the data on these problems were few and the design methods for the frames with these walls were not established. In this paper, it was attempted to consider the influences of the spandrel or wing walls in the structural frame analysis and the proportioning of the members, and the results of analysis were compared with the results of statically loaded tests. The results for the ultimate bending strength and for the shear strength at creaking were compared in Table 3. The initial regidities were compared with the results obtained from the various methods of analysis in Table 4. The hysteretic characteristics at the cyclic loading in plasticity were discussed in Fig. 12-Fig. 15.

In this paper, a method of elasto-plastic analysis of orthogonal space frames utilizing the slope-deflection method is presented. We now consider the equilibrium equations for the deformed state of members which compose a space frame and by taking the time derivative, we obtain the relation between the rate of end moments and the rate of deformations. By solving above simultaneous differential equations utilizing the finite difference method, the coefficients in the basic equation of slope-deflection method of each member are determined numerically and equilibrium equations of the entire framing system are set up at an arbitrary loading state. We repeat solving the equations adjusting the coefficients of the basic equation of each member by using the method of incremental-load analysis until the convergence of deformations after the load increment is attained. The work described herein presents exact method for analysing the elasto-plastic behavior of space frames and is applicable to orthogonal multi-story space frames, provided that no change in axial force of columns takes place during loading, and some assumptions made to simplify the analysis are acceptble.

In the former report, the author suggested a new procedure of the theoretical analysis to estimate the behaviours of a pile foundation under vertical load. Some important problems about the theory and the practical analysis are discussed in this paper. The series of eqations which compose the analytical system is one of the approximate solutions to the fundamental differential equation concerning the frictional resistance on a pile circumference. The appropriateness of assumptions, which are to be used in the analysis-such as the non-linear relation between shear stress and displacement along a pile shaft, and the linear relation between reaction and settlement at the pile tip, is examined by comparing computed values with load test results. Pre-determination of constants, which are to be substitued to thet series of equations, is surely important to obtain reasonable result, but those constants are always variable not only with every change of soil characteristic but also with that of piling process. Some test data available to assume the shear strength along the pile and the modulus of pile-tip displacement are represented to be referred.

Das Hauptanliegen des Artikels liegt darin, die Baukunstlerische Idee und ihre Verwirklichung bei Rudolf Steiner (1861-1925) zu betrachten. Er ist innerhalb der modernen architektonischen Geschichte noch unbekannt, obwohl er zum inhaltvollen Reichtum der modernen Architektur beigetragen hat. Steiner als bildender Kunstler ist hinter seiner umfangreichen Tatigkeit als Geisteswissenschaftler verborgen. Jedoch ist er nicht in die Hauptstromung der modernen Architektur, z. B. des Bauhauses oder des Funktionalismus einzugliedern. Wie Antonio Gaudi mit der Stromung des Jugendstils oder des Expressionismus keine Beziehung hatte, war Rudolf Steiner auch in seiner grundlichen Art und Weise, wie er die Architektur erfasste und verwirklichte, von diesen Beiden sehr verschieden. Ungefahr in derselben Zeit, wo das Bauhaus in Weimar die verschiedenen Kunstarten unter der Architektur vereinigen wollte, hat Steiner die Architektur durch die Malereien der Deckengemalde der groβen und der kleinen Kuppel, rote, grune, blaue, violette, rosa Glasfenster und die Holzplastik der "Gruppe" im ersten und zweiten Goetheanum in Dornach bei Basel in der Schweiz zu einer nicht nur theoretischen, sondern auch verwirklichten synthetischen Kunst erhoben. Die gegenwartige Bedeutung, die Bauten von Rudolf Steiner haben, muβ nun richtig erkannt werden.
