项目摘要

(1) From loading tests of buttresses in caissons for harbor it was clarified that ultimate capacities of composite buttresses are slightly greater than those of reinforced concrete (RC) buttresses, that compression failure of concrete and shear failure with yielding of steel plates take place, and that the observed capacities are greater than those predicted by the equation for deep beams in JSCE specification.(2) It was indicated by pure torsion tests of RC and composite buttresses that the yielding torsional moments are the same for both types, that the torsional moment increases after yielding in the case of composite buttress, and that the expanded analytical method by Hsu can be applied for prediction.(3) The experiment and analysis for shear capacities of sandwich members indicate that either truss model or statically indeterministic truss model evaluate the shear capacity in both cases in which only diaphragm is placed and in which full web and diaphragm are placed. In the case … More in which only full web is located, the through investigation on shear force components carried by compression zone, diagonal cracking zone, shear reinforcing steel plate and flange plates in compression and tension was conducted.(4) Establishment of a mechanical model on deformation of shear connector and proposal for calculation model of shear force transfer strength were made by conducting experiments on deformation of shear connector and bond of embossed steel plate, respectively.(5) The analysis on failure of steel anchor plate embedded in concrete was done by RBSM,which could predict cracking properly.(6) It was disclosed in the punching shear test of open sandwich slabs that the punching shear capacities are less by 30% than those of RC slabs with the same reinforcement ratio.(7) Effects of amount of steel jacket on ductility and variation of shear force components with deformation were clarified by the reversed cyclic loading test of RC columns retrofitted with steel jacket.(8) For self-compacting a concrete rational mix design for mortar and a cite test for total amount were proposed and the role of viscosity agent on compactability of fresh concrete was clarified.
