Generally molded cylinders are used to determine the splitting tensile strength of concrete, but the strength is often influenced by supplementary bearing bar or plate. Then we tried to measure the tensile strength using portions of beams broken in flexure. First we chose some loading methods and investigated them by stress analysis. The stress analysis indicated a loading method by which the specimen had good stress distribution. Second we examined the loading methods and bearing bars by experiments. The experimental results showed that by the loading method mentioned above and by a kind of bearing cylinder the tensile strength could be known using portions of beams broken in flexure. In this paper the testing method we proposed is explained in detail to determine the splitting tensile strength, which was theoretically reasonable and snowed good experimental results.

Many experimental studies of laterally braced steel beams have been achieved to know the rotation capacity of plastic hinge, but in most of them, the lateral movement of bracing point entirely constrained, and the effects of the rigidity of lateral brace on the rotation capacity and on the lateral bracing force have not been well established. In this paper, the followings are investigated by finite element method based on the theory of thin-walled beam-shells of open cross section ; (1) the relation between the rigidity of lateral bracing and the rotation capacity of plastic hinge, (2) the relation between the rigidity of lateral bracing and the lateral bracing force. And from these results, the necessary rigidity and strength of lateral bracing are decided to achieve a desired rotation capacity.

Based on geometrical assumptions and principle of virtual velocity, finite displacement equilibrium equations and their boundary conditions are generally derived for thin-walled members with open section in incremental form which is usefull for elastic-plasitc analysis. And the relations between resultant stress rates and velocities are also derived in both elastic and plastic ranges. The proposed theory is a direct generalization of the elastic buckling theory established by Vlasov and it includes Vlasovs' theory as a special case.

In the case of the visual angle of a visual object is sufficiently large, usually almost constant shape perception is yielded in spite of the change of fixation point which is optionaly selected on the object. In this paper, this problem of stable perception, besides with the problem of constancy as the meaning of regression to the real object were investigated by the application of &lrtri;-transformed figure II&lrtri;. First, some trials of measurement of shape stableness on the perception of a obliquely viewed square were considered. Second, the stableness of perspective declination of vertical sides of a obliquely viewed rectangle which stands upright was investigated by means of II&lrtri;, in conditions of fixation point variated on the center line of object. Third, the invers perspective which is a kind of overconstancy was investigated, in was found that the conditions exist that yield a upward divergence about vertical parallel sides of a rectangle in II&lrtri;. Moreover, the characters of the overconstancy under the detailed conditions on arrangement of object were shown. Further, some results of previous experiment under the similar situation were also considered.

Such as relating andgrasping various condition, or grouping architectual space according to their mutuality, in design process, we must analyze and grasp very abstract conception and put them into concrete shape. In this research, we developed "Grouping Method of Markov Model" as a means to contribute toward fixing the image of designers by quantifying, or communicating it to a third person. The characteristic of this method exists in Markov Model, namely in the point to group the mutuality of elements-condition of planning or space, which constitute these conception as a Markov chain in probability process. In this treatise we give an explanation and practical example of this method the following : Chapter 1 Explanation of Markov Model Chapter 2 Explanation of weighting and grouping Chapter 3 Example (Grouping characterized rooms of dwelling)

This paper is the study on the custom of the disposition of Kasuga Shrine's obsolete buildings and the distribution of Kasuga style. The contents are follows ; Introduction Chapter 1 : The disposition of the Four Main Shrines and Wakamiya Shrine. Chapter 2 : The disposition of the Small Shrines. Chapter 3 : The price of obsolete buildings. Chapter 4 : The custom of the disposition and the method of the transportation of obsolete buildings. Conclusion The results are followi ; 1. During Japanese middle ages, it was the customary practice to use obsolete building materials of the Fourth Main Shrine for the shrine in Otzuki village (Tenri city in Nara), obsolete building materials of Enomoto Shrine for the shrine in branch temple of Kofuku temple and obsolete building materials of Kii Shrine for Tatzuichi Shrine (Daianji-cho in Nara). 2. Many obsolete buildings of the Four Main Shrines and the small shrines were used for local shrines in Kofuku-ji's and Kasuga's territories, ones in regions which Shinto priests had been living, ones which were intimately connected with Kasuga Shrine and branch shrines that there were out of the Kasuga's area. 3. I think that there is a direct relationship between the custom of reconstructing buildings at regular intervals and the fact that Kasuga's obsolete buildings were used for other shrines. 4. As a general rule, obsolete buildings were transported in sections after being torn down, but sometimes obsolete buildings were moved in tack to another place.
