Collapse Patterns and Their Discrimination of Reinforced Concrete Shear Wall Under Combined Stresses of Compression and Shear due to Strong Earthquake

doi:10.1007/s12204-020-2175-2

Abstract

Abstract: The collapse patterns of reinforced concrete (RC) shear walls under seismic load are proposed. The
crack distribution and propagation of shear walls are specifically based on the failure criterions of Mohr-Coulomb
with tension cutoff. Three zones and five different corresponding failure modes of RC shear walls are determined
according to the transfer path of shear stress in shear wall. These failure modes of shear walls under seismic load
are verified by many experimental results and can be utilized in collapsing analysis for frame-shear wall structure.
