EXPERIMENTAL STUDY ON SEISMIC BEHAVIOR OF REINFORCED CONCRETE CORE WALL
In order to further study the seismic behavior and influencing factors of reinforced concrete core wall, three reinforced concrete core wall models with large height-width ratio were built and tested to failure under the combined action of constant axial load and reversed cyclic lateral load. The axial compression ratio and span-depth ratio of coupling beam of each core wall were focused on. This paper presents the results, including failure mode, hysteretic behavior, load-carrying capacity, ductility, energy dissipation ability, shear lag effect. The final overall bending damage occurred at the bottom of each model. When the axial compression ratio increasing or span-depth ratio of coupling beam dropping, stiffness and load-carrying capacity of the specimen had risen markedly, but the ductility performance dropped significantly. It can be concluded from the analysis that the axial compression ratio and span-depth ratio of coupling beam both have important effects on the seismic behavior of reinforced concrete core wall.
