A computationally efficient framework for the simulation of the nonlinear seismic performance of infilled RC frame buildings

This study proposes a novel approach for the computationally efficient numerical modeling of nonlinear seismic response entire buildings with infilled RC frames. The proposed framework can be particularly helpful multiple stories and complex layouts, which current methods cumbersome to implement, or inaccurate. combines force-vs.-displacement every bay building obtain envelop curves floor along two main perpendicular horizontal directions. These are used calibrate box-type model building. methodology is employed simulate two-bay, three-story frame tested on shake table, an instrumented four-story school in Nepal, damaged by 2015 Gorkha earthquake. comparison results test field data indicates that accurately capture important features actual structures their dynamic properties.
