The standard for quality control of concrete to easily slide up the form in sliding form method has not established. To rationalize this method, the speed of sliding up the form must be decided as the lost time according to the main types of occupation, that is workmen for concrete and reinforcement, waiting without working reduces to a minimum. To keep the adequate construction progress it is desirable for the speed of sliding up to be kept constantly or not more than several kinds. The compressive strength of concrete at early age is sensitively influenced by weather conditions. So past weather conditions corresponding to the construction period must be investigated and arranged. By using of this results the mixing strength of concrete must be revised by the standard value of a revised value t of the compressive strength of concrete according to temperature shown in Table JASS 5. 3. 3. The necessity of the sufficient preliminary investigation on weather conditions and material of concrete for the sake of preparing the several kinds of mixing of concrete to secure the necessary speed of sliding up is pointed and peculiar items to investigate adding to those of general concrete works is pointed, too.

This report shows experimental results as for sliding displacement behavior of high-tensile-bolted friction joints under tensile load subjected to high temperatures up to 450℃. After evaluation of the load-sliding displacement curves, the following conclusion could be drawn : 1) There in little difference in the slip loads between tests in a heated state and after cooling. 2) A decrease is slip-load up to 350℃ is little. 3) Above 350℃, there is a rapid decrease in slip-load and the sliploads at 450℃ are 30 to 59 percent of room temperature's. 4) At 250℃ heating condition, there is a large increase in slip-load, in the case of the specimens with comperatively small friction factor at room temperature.

Recently, many High Strength Steel Bars is used in reinforced concrete structure. But, there are no studies solved this question "How high strength steel bars can be utilized effectively in R. C. members?". Solving this question is very important to development of high strength steel bars. This study gives an anser to this question. First, this study proves that the steel strength could be utilized effectively in R. C. members, have an upper limitation, and that this upper limitatinn is restricted by the following voluable conditions. Secondary, in this study, this upper limitation restricted by the following conditions is analyzed by theoletical caluculation. (1) Ultimate bending strength of Beam and Colum. (2) Bending ductility of beam and colum. (3) Shear strength of beam and colum. (4) Shear failure of beams and colums connection. (5) Reduction of Bending Strength by the bars settled through the beams and colum connection. (6) Anchor failure of bend bars. (7) Allowable crack width. (8) Allowable deflection of beam. (9) Allowable deflection of colum at earthquake.

The present paper is a the retical study of a continuam mechanics of shell structures composed of grid works. The equiliblium equations of stresses, stresses, functions, compatibility equations of strains and boundary conditions are discussed in two cases, of which one is in an ordinary field of six kinematical freedoms, the other is in a macro rotation field. The theory which has six fredoms is classified as a micro polar elastisity or a couple stress theory. Macro rotation theory is equal to ordinary shell theories neglecting shear deformations. The necessary relation to analyze such a shell, the constitutive equations are discussed. The method to get constitutive equations is illustrated and in plane behaviors of grid works are formulated into constitutive equations.

According to AIJ-Specification for Steel Construction, the magnitude of the bracing strength must be taken as F≥0.02P where P is equal to compressive force and F is the bracing strength. However, in a case where a lateral support has nots sufficient stiffness, even though its strength is large enough, the compression member deflects excessively and its strength does not reach the expected strength P_<cr>, which is the strength of the fully braced member. Hence the lateral support with insufficient stiffness does not play a role of support. Up to the present, few precise studies on this problem have been done. Therefore, in this paper, we examined, first of all. the lower bounds of sufficient bracing strength and stiffness in order that compression members with initial imperfections, hinged at both ends and laterally supported at the center, can reach the expected strength P_<cr>. Then the following conclusion is obtained. "Even though the lateral support of a compression member has the larger strength than 0.02P_<cr>, the strength of the compression member cannot reach P_<cr> unless the stiffness of the lateral support k satisfies the following requirement, k/k_0≥0.7 where k_0=0.02P_<cr>/(L/1000). The above requirements are available when the slenderness ratios of compression members L/i are within the range, 20≤(L/2)/i≤200

This paper describes on the interior and exterior ornamental details in the Ueno Museum on the basis of the plans. J. Conder selected the pseudo-Saracenic style and moreover chase the Japaneseque taste for it's designs and imparted an Eastern character to it. He designed putting stress on the exterior ornaments because interior was occupied by many exhibition rooms and these rooms were not required ornaments so much.
