By using masing-rule to determine LRB's resilience and loading-unloading process,its instantaneous stiffness is calculated in the ground motion,then,the masing-rule is applied into Newmark-β to solve nonlinear dynamic problems.By establishing processes,the algorithms of the examples are analyzed.The results show that this method is effective,and some conclusions are summarized about how the seismic responses would be affected by isolation period changing.
