［摘要］簡單介紹了LS-DYNA在土木工程領域的常用材料模型和分析單元，包括塑性鉸模型、纖維模型和分層殼模型。在此基礎上詳細介紹了LS-DYNA在兩個復雜超高層結(jié)構(gòu)設計中的應用，對結(jié)構(gòu)以及各關鍵構(gòu)件在罕遇地震下的性能進行了詳細描述，證明了LS-DYNA在復雜結(jié)構(gòu)整體彈塑性分析領域的適用性和可靠性，說明了非線性分析工作在性能化設計過程中的重要作用。［關鍵詞］LS-DYNA; 彈塑性分析; 塑性鉸模型; 纖維模型; 分層殼模型中圖分類號：TU318 文獻標識碼：A 文章編號：1002-848X(2015)23-0065-07
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
