摘要
简单介绍了LS-DYNA在土木工程领域的常用材料模型和分析单元,包括塑性铰模型、纤维模型和分层壳模型。在此基础上详细介绍了LS-DYNA在两个复杂超高层结构设计中的应用,对结构以及各关键构件在罕遇地震下的性能进行了详细描述,证明了LS-DYNA在复杂结构整体弹塑性分析领域的适用性和可靠性,说明了非线性分析工作在性能化设计过程中的重要作用。
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.
