Abstract:The composite wall made of a gutter, a pre-cast embedded mold and cast-in-place concrete looks like as if it is one unit structure. However, the boundary of gutterfs sidewall and basal plate, which is made of a pre-cast embedded mold and cast-in-place concrete, is not strengthened by reinforcement bars, metal fixtures and etc. Therefore the wall exhibits very complicated deformation behavior when horizontal loading is applied. Furthermore, it is difficult to calculate yield strength and deformation by existing design procedures. In this study, the strength and deformation were measured directly using a trial product. Then, the possibility of evaluating the strength and deformation characteristics through 3D FEM frame analyses and 2D RBSM (Rigid Bodies Spring Model) is studied on the basis of experimental results.
