Abstract:
For effectively simulating the seismic behavior of strain hardening cementitious composites(SHCC)members, a uniaxial cyclic constitutive model for SHCC was proposed. The ascending branch of the compressive envelop curve was imitated by using the form of parabolic curve; while the bilinear form was adopted for the descending branch. A trilinear form was used to imitate the ascending, strain-hardening and descending branches of tensile stress-strain curve. By the method of setting reference point, the rules of unloading process were determined in consideration of the partial unloading-reloading scheme. Furthermore, the transition between tension and compression was considered in the cyclic model. The proposed cyclic constitutive model was coded by OpenSEES software and applied to simulate the material and component tests. The simulation results indicate that the proposed model is reasonably accurate in simulating the mechanical properties of SHCC and the cyclic behavior of SHCC flexural element.
