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。
LS-DYNA briefly introduces the commonly used material models and analysis elements in civil engineering, including plastic hinge model, fiber model and layered shell model. On this basis, the application of LS-DYNA in the design of two complex super high-rise structures is introduced in detail. The structure and the performance of the key components under rare earthquakes are described in detail. It is proved that the LS-DYNA The applicability and reliability of the field of plastic analysis illustrate the important role of nonlinear analysis in the performance-based design process.
