超高层建筑外挂重型塔式起重机的计算加固浅析

Analysis on the Calculation and Reinforcement of Heavy Tower Crane for Extra High Rise Building

以成都安邦金融广场为工程背景,介绍超高层建筑核心筒外挂重型塔式起重机的有限元计算、分析、加固方法。采用MIDAS/GEN 2014进行整体受力分析、剪力墙平面外受力计算;Abaqus6.14进行整体加局部细化多尺度建模验算,局部实体建模能够得到较为准确精细的节点分析结果;并复核剪力墙裂缝宽度,多角度保证主体结构安全。

Based on the engineering background of Chengdu Ampang Financial Plaza,this paper introduces the finite element calculation,analysis and reinforcement method of a heavy tower crane with a core tube mounted on a super high-rise building. Calculation by MIDAS GEN 2014 analysis and overall shear wall by Abaqus6. 14. The overall and local refinement of multiscale modeling calculation,local modeling results can be more accurate and precise node; crack width checking shear wall,multi angle to ensure the safety of major structure.
