In the previous paper, we have reported about the elastic behavior of beam-to-column connections in thick wall tubular columns considering the variation of shearing stress distribution in wall thickness. In this paper, we compare values of Saint-Venant's flexure theory which we have solved in the previous paper with values of shear flow theory. In the first, we discuss difference of maximum shearing stress and shearing strain by ratios of outside diameter and wall thichness. And then we discuss the yield of bending and the yield of shearing force considering both ratios of outside diameter and wall thickness and ratios of beam-depth and outside diameter of connections. Finally, we consider the deflection of connections due to bending and shearing force.

As far as we are informed on this subject, there have been some studies which discuss the sun-exposure time during the day or shadow areas as a function of time around the structure facing due south and of rectangular form. This method is by no means practical. Urban structures are built randomly, regardless of direction or position, and most of them are accumulation of many cubes. We, in this thesis, have computed the sun-exposure time on the urban site influenced by the above mentioned structure, and have discussed some of the problems which arise in the process of computing and the solutions for them. we used a line printer as the method of output, believing that it is superior in popularity, convenience and applicability. We showed the sun-exposure time graphically on the reduced site plan. Applying the method to two site plan of Japanese high density apartment houses, and further, to one British one, we compared them with each other.

The aim of this study is to find a simple method for the regional analysis. It should classify an are a in comparison with the others using a mesh analysis. This study concerns Chiyoda Ward in Tokyo. At the beginning we have made the categolically classified map in 42 cases, and estimated the co-relationship inbetween two parameters out of 42. Then we analyzed the 42 parameters by Varimax-method. For the purpose of making an homogeneous ares, we show three method. 1. Using the factor analysis, we pick up 8 parameters, -population, total length of sidewalk, total floor area of whole building, trafic accidents, area of park and green space, area of land use for housing, number of enterprices, number of telephone, we show the fan shape graph which means the classification from to 9 grades on the centrifugal direction. We distinguish several meshes by this pattern. 2. Exchanging a relationship between mesh as a data and parameters, we classify each mesh into 8 factors. In this case, some meshes which belong to the same factor should be same characteristics accumlating datas of 42. 3. Using the same 8 parameters as No.1, but calculating the weight vector by the computer, we count the factor score of each 8 parameters, then with the first three factors, we have got the eight different combinations. Conclusion; A meaning of each method should be a little different, but the pattern in result are similar. The first method is very significant. However, We utilize the second and third methods in stead of the first.

This paper describes on the progress of the construction, the actions of Conder, the engineers in charge of the Department of Public Workes, the block planning, the planning of the Prince KITASHIRAKAWA, s Residence completed in 1885, and considers on the significance of the Prince ARISUGAWA'S Residence and the Prince KITASHIRAKAWA'S Residence. These Residence was constituted with European style house and Japanese style house. The former was used for Prince and the latter used for the employees. These Residence had long remained the model of the residence of the lmperial Family and the residence of the upper classes in Meiji era.
