Application of LS-DYNA software in building structure elasto-plastic analysisLiu Hao, Zhong Congming, Liu Peng(Arup, Beijing 100020, China)Abstract: The common material models and analysis elements of LS-DYNA software in civil engineering field were briefly introduced including plastic hinge model, fiber model and multi-layer shell model. On this basis, the applications of LS-DYNA software in two complex super high-rise structures were introduced in detail, and the performances of the structures and key members under rare earthquake were described in detail. Analysis shows the applicability and reliability of LS-DYNA software in the field of overall elasto-plastic analysis of complex structure, and shows the important role of nonlinear analysis method in the process of performance design.Keywords: LS-DYNA software; elasto-plastic analysis; plastic hinge model; fiber model; multi-layer shell model
