[摘要] 主要介绍了MIDAS Building中进行动力弹塑性分析的一些基本理论和特色功能。首先可以利用施工图中的钢筋数据计算塑性铰特性，结果更加准确；可以校审选择的地震波并对其自动调幅，保证所选地震波满足规范要求；程序提供了比较丰富的滞回模型用于模拟结构中的梁柱构件，用纤维模型来模拟剪力墙构件，考虑了轴向变形、弯曲变形和剪切变形；后处理中提供了丰富的二维和三维图形结果以及各种表格结果，方便用户整理弹塑性分析报告。

Abstract: The basic theory and characteristic function about elastic-plastic dynamic analysis in MIDAS Building was mainly introduces. Firstly, in MIDAS Building, the final arrangement of reinforcement could be used to calculate the property of hinge, which make the reuslt more accurate. Seisrmc wave could be automatically chosed and its amplitude could be adjusted by software to satisfy the requirement of the standard. Abundant hysteresis models are provided to simulate beam and column member, fiber model was used to simulate shear wall member, which could consider axial, bending and shear deformation. In post-processing, all kinds of 2D and 3D grapluc result and table results are porvided, which could be used in elastic-plastic analysis report.

Keywords: MIDAS Building; elastic-plastic dynamic analysis
