Numerical Analysis of Post-Tensioned Coupled Wall


Article Preview

Based on OpenSEES, nonlinear beam-column element based on fiber model and considered nonlinear shear deformation was used to simulate wall limb; zero-length elements were used to simulate action of prestressing tendon and connecting reinforcement in the interface between coupling beam and wall limb; the hysteretic models of the zero-length elements were established by programming. The low-cyclic loading tests of two PCW specimens were introduced. Results of the numerical analysis and the tests indicate that elasto-plastic performances of PCW can be well simulated by numerical analysis, analysis model based on OpenSEES can be applied to non-linear analysis and of good precision; PCW is of good self-centering ability with little residual deformation after unloading, and damage concentrating in certain parts that can be repaired after earthquake; energy dissipation capacity of PCW is increased because of the connecting reinforcement.
