摘要: 连体结构的受力特点与单体结构相比有明显的差异,某些特殊连接形式的结构设计尤其值得探讨和研究.以两个实际工程案例为依托,针对其刚度不对称、高位连接、大跨度连接体等特点,分析并总结连体形式的选择、设计方法和优化加强措施等. 在结构整体作用层面,提出巨型框架简化概念,并采用水平变形等指标评价扭转效应;在结构受力层面,对大跨度连接体受力、施工模拟、复杂节点设计等若干连体结构设计关键点进行了分析,并提出了对策.

Abstract: The force characteristics of the connected structure are obviously different from those of the single structure, andthe structural design of some special connection forms is particularly worth exploring and studying. Based on two practicalengineering cases, according to the characteristics of asymmetric stiffness, high connection and large span connection, theselection of connection form, design method and optimization strengthening measures were analyzed and summarized. At theoverall action level of the structure, the concept of mega⁃frame simplification was proposed, and the torsion effect wasevaluated by indicators such as horizontal deformation. At the structural force level, several key points of connectionstructure design were analyzed such as the force of large span connection, construction simulation and complex nodedesign, and the countermeasures were put forward.
