Abstract:In a framed shear wall, the wall panels are subjected to shear forces as well as to vertical loads. After diagonal cracking, a truss-like action is formed in a panel, in which the compression struts are subjected to compression and the longitudinal and transverse reinforcement are in tension. The governing equations of this unit can be derived from a softened truss-model theory, wherein the stress-strain relationship of the concrete struts is modeled by a softened material law. The complete load-deformation history can be solved numerically. The theoretical predictions agree very well with the experimental data of 14 test specimens reported in the literature. A simple theoretical formula is given for ultimate strength, which includes the significant effect of the vertical stress.
