天津津塔结构钢板剪力墙力学性能分析
|
摘要
天津津塔是一栋高336.9m的钢结构超高层建筑,主要抗侧力体系采用"钢管混凝土柱框架+核心钢板剪力墙体系+外伸刚臂抗侧力体系"组成。薄钢板剪力墙结构作为一种新的结构体系,充分利用薄钢板的拉力场效应,具有较大的弹性初始刚度、大变形能力和良好的塑性性能、稳定的滞回特性等优点,但在国内还没有先例。本文针对钢板剪力墙建立4个不同参数局部模型并采用ANSYS有限元分析软件进行弹塑性分析得出了钢板剪力墙的力学性能规律。
Tianjin Jinta is a super high-rise building with 336.9 meters high,the main lateral-resistance system consisting of"concrete-filled steel tube column frame+steel plate shear wall core tube+outrigger system".As a new structural system,thin steel plate shear wall structure have greater flexibility in the initial elastic stiffness,better plastic performance and much more stable hysteresis,etc,by making full use of tension field effect.There is no precedent project in China.Four different parameters of part of real structural models are set up for elastic-plastic analysis of steel plate shear wall mechanical behavior by using ANSYS finite element analysis software.
