重庆高科太阳座项目结构设计中的复杂连接点与关键点分析

Analysis of complex connection joints and key joints in the design of Chongqing High-Tech Solar Block project

为了研究超限高层中复杂连接点及关键点设计,建立了重庆高科太阳座项目结构设计中复杂连接节点的数值模型,详细分析了V形和X形节点中不同形式节点(分叉柱节点、直接相贯节点、支管底部与主管端部交汇节点)的力学行为。结果表明,本工程节点符合规范要求,超限高层节点受力复杂,需要分别考虑是否有混凝土情况;对于合仓柱形式及有内隔板的复杂节点,需要对合仓柱和内隔板的力学行为单独分析。

In order to study the complex connection joints and key jointts design in the super high-rise building, the numerical model of the complex connection joints of Chongqing High-Tech Solar Block project was established, the mechanical behaviors of different forms of joints(bifurcation column joints, direct intersecting joints, intersection of the bottom of the inclined column and the end of the main column) in the V-type and X-type joints were analyzed in detail. The results show that the design of the joints in this project meets the requirements, and the forces on the super high-rise joints are complicated. It is necessary to consider whether there is concrete condition separately. For the complex joints with the combination column forms and internal partitions, it is necessary to analyze the mechanical behavior of the combination column forms and internal partitions separately.
