nonlinear finite element analysis of solid hybrid precast shear wall under hysteresis loading

collapse prevention of structures is one of the main aim in seismic design code. though, experiences exhibit that most of structures in sever earthquakes receive damages and residual displacements. such permanent displacements prevents serviceability and in some cases impose repair costs. on the other hand the seismic design of self-centering system exhibits excellent performance regarding the energy dissipation, low damages and minimizing the residual displacements. the use of “hybrid” precast concrete wall structures for high seismic regions provides ample rocking mode of behavior and reduces the residual top displacements. this paper presents a three dimensional nonlinear finite element (fe) models, using abaqus to predict the lateral force-lateral displacement of the precast concrete shear wall specimen. the numerical analyzed carried out under both gravity and reversed-cyclic lateral loading to investigate their seismic nonlinear behavior. the obtained results indicate that the nonlinear numerical results of tested specimen are mutually correlate to the experimental results.
