季华实验室某超限高层建筑结构设计

Structural design of a tall building beyond code limits in Jihua Laboratory

季华实验室B4栋为科学辅助用房,采用框架结构,为连体结构。该结构为具有扭转不规则、楼板不连续、连体、局部不规则等不规则类型的超限高层建筑。本文从结构体系与布置、结构超限分析与计算模型、专项分析、超限设计措施及对策等方面进行介绍分析。

Building B4 of Jihua laboratory is a science auxiliary room. It is a conjoined structure and uses the frame structure system. The structure is identified as an exceed-code high-rise building with some irregular characterictics such as torsion irregularity, floor discontinuity, conjoined, local irregularity. The structural system and layout, structural overrun analysis and calculation model, special analysis, overrun design measures and countermeasures are presented.
