In the present paper, properties and possible use of granulated slag and processed granulated slag as fine aggregate in concrete are discussed experimentally. The results obtained are listed below. 1. Granulated slag is not suitable for fine aggregate in concrete, because it is inferior in its grain-shape and grading. 2. There is a prospect of the applicability of processed granulated slag as fine aggregate in concrete. 3. Compressive strength of the mortar and concrete depends on the finessmodulus of processed granulated slag and the lower the finess modulus, the higher the strength. This tendency was outstanding in long-term tests. If the fineness modulus of aggregate was less than 2.4, a higher degree of strength was obtained than the one of the concrete made use of river sand. 4. In the mortar and concrete made use of processed granulated slag, unit water content requirement was more than in that made use of river sand. But, in the strength and shrinkingtest, the properties of concrete made use of processed granulated slag were similar to those made use of river sand.

In order to clarify the dynamical characteristics of a water-saturated sandy soil ground, in this paper, the authors apply the theory of dynamical ground compliance, which is one of the methods estimating the dynamical properties of a sub-soil ground, to an interaction problem between a circular foundation and a water-saturated elastic half space. In Sec. 2 are derived the analytical solutions of statical and dynamical ground compliance of the circular foundation subjected to a vertical harmonic excitation on the semi-infinite aggregate body with surface boundary permeability condition, i.e. with pervious or impervious boundary condition. They deduce the analytical results about the average stresses in the porous elastic solid and the pore water at the loading area respectively. In order to investigate the dynamical effect of the second kind waves in the aggregate body, in Sec. 3 is discussed the method to simulate the dynamical characteristics of the soil aggregate with those of Voigt-type viscoelastic body by using such the properties of the first kind dilatational and rotational wave as phase velocity and attenuation facter of each wave in the soil aggregate. And also they discuss how to choose any kind of measures for the evaluation of the dynamical characteristics of a sub-soil ground in consideration of such physical quantities as dissipation energy through ground and elastic potential energy. In sec. 4 are decided the actual values of constants and coefficients in the multi-phase medium for numerical processing, and in Sec. 5 they investigate the numerical results of the average stresses of the porous elastic solid and the pore water at the loading area respectively.

Following remarks are obtained from this investigation. 1) As for the influence of weld defects on the static strength of butt joints, the contribution ratio of the defective area is far larger than other factors. And for the percentage elongation of butt joints, the contribution ratio of the difference of welding procedures is almost as large as that of the defective area (see, Table 4). But the influence on both the static strength and the percentage elongation of butt joints doesn't differ from the difference of the kinds of weld defects induced artificially. 2) For the influence of weld defects of the same total defective area on the static strength and the percentage elongation of butt joints, there are no substantial differenced between joints with single defect and joints with multidefects. 3) The uniform elongation of butt joints is not influenced by the mode of fracture, ductile mode or brittle like mode. And uniform elongation over 5% has been obtained in joints whose defective area is less than 2% of the gross sectional area of the joints. 4) As for butt joints whose plate thickness is thin or medium, the assessment of welded joints by the length of weld defect can be possible with some grounds. But as for thick plate, the assesment of welded joints only by the length of weld defect has not reasonable grounds. 5) As the height of flaw echo has little correlation with the static strength of butt joints, the subdivision of the range of echo height is meaningless for the assessment of welded joints.

Numerical response analysis was made using various kinds of vibrational systems with degrading restoring force characteristics and the collapse conditions for those systems were evaluated in connection with the responses of the elastic-perfectly plastic systems. In multi-storied structures the degradation of strength in a story results in concentration of destructive energy into the story and when the decrease of strength reaches a certain value, the degraded story can collapse. Degrading ratio was defined as the ratio of the decrease of horizontal resistant force to the initial yield strength in a specific story. Proposed collapse criterion was expressed in a form of the critical value of the degrading ratio. It is important to note that in the multi-storied structure a little amount of decrease of strength in a story promotes concentration of energy and can cause the collapse of the entire structure.

In plastic design, the method of superposition are not helpful for the analysis under the superposed load. Therefore, the structure should be treated generally as the three dimensional frames on the occasion of elasto-plastic analysis. And it is also important to understand the characteristic of the three dimensional elasto-plastic behaviour. The purpose of this study is to clarify the characteristic of the three dimensional elasto-plastic behaviour on steel rigid frames. In this paper, the small scale tests were undertaken to investigate the characteristic behaviour different from that of planar frames and to get the data to establish the simple method of three dimesional elasto-plastic analysis. Test specimens were two stories-one bay rigid space frames constructed with H-section members and were tested under horizontally loading combined with axial load. From these experimental results, the followings were clarified, (1) The displacement v_1/h, v_2/h at ultimate horizontal load were 0.015〜0.030 and it's greater than that of planar frames. (2) In case of planar frames, the stability limit does not exist under the axial load less than 0.3 P_y, but tests' results indicated that the stability limit exists under the axial load less than 0.3 P_y in the three dimensional behaviour. (3) The three dimensional analysis by plastic hinge method does not often give the adequate estimation for the load-deformation relationships, especially after ultimate horizontal load. (4) The influence of warping restrained is increased by increasing the slenderness ratio and axial load of the columns.

This paper examines the form of Tsune-goshos in Seiryo-den of three palaces, Nijo-Tomikoji (1317〜1336), Oeido (1402〜1443), Kosho-do (1456〜1590). As the result, the following facts have been clarfied. 1. The Tsune-gosho of Kosho-do Palace consists of three rooms called Tsune-gosho, Rentai, and Hisashi which are respectively in Moya, Hisashi, and Mago-bisashi. 2. The characteristic fittings such as Chodai-gamae, Naka-bashira, different level floors, Shitomi lattice, etc. appeared with the expansion and the progress of the Tsune-gosho. 3. The form of Tsune-gosho of Kosho-do Palace is inherited in the form of three rooms used for official affairs in Tsune-gotens built in Edo period. 4. The room in South row (Edo preiod) which corresponds with the Hisashi (Kosho-do) becomes similar to the form of ordinary Gedan, by losing the factors which image "Hisashi". 5. The Gedan of the three rooms of south row is the transitional form of Hisashi to Gedan, and this is one of the steps in the forming process of Jodan.

'Kichizaemon party' is one of the carpenter's party in Settsu country (now, Osaka and Hyogo prefecture). This party are also one of the carpenter's parties that are governed by Nakai family (A director of Kyoto branch of the works in Tokugawa government) in six countries at Edo Period. It's history able to trace by many written documents which are covered all of "Kichizaemon party" from early to late Edo period. In the history of a party, we know that it's organization change at 1709 A. D., Before this time the organization is consisted of the partners in Shimakami, Shimashimo, Teshima, Nose and Kawabe county, but after this time in only Shimashimo county. At the early phase, a number of the partner are 74 persons in the beginning, and increase 214 persons at 30 years after. In consequens of the increas, there are made many problems for the control of party's head. A reforme of the organization are made up of the regional circles, and are operated by a conferation between all circles and a party's head.
