高德志， 侯曉武， 趙 繼(北京邁達斯技術有限公司，北京100044)[摘要] 主要介紹了MIDAS Building中進行動力彈塑性分析的一些基本理論和特色功能。首先可以利用施工圖中的鋼筋數(shù)據(jù)計算塑性鉸特性，結果更加準確；可以校審選擇的地震波并對其自動調(diào)幅，保證所選地震波滿足規(guī)范要求；程序提供了比較豐富的滯回模型用于模擬結構中的梁柱構件，用纖維模型來模擬剪力墻構件，考慮了軸向變形、彎曲變形和剪切變形；后處理中提供了豐富的二維和三維圖形結果以及各種表格結果，方便用戶整理彈塑性分析報告。[關鍵詞] MIDAS Building；動力彈塑性分析中圖分類號：TU313.2 文獻標識碼：A 文章編號：1002-848X(2012) S2-0217-04Elastic-plastic dynamic analysis in MIDAS BuildingGao Dezhi, Hou Xiaowu, Zhao Ji( Beijing MIDAS Information Technology Co., Ltd., Beijing 100044, China)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
