武汉光谷电竞馆建筑结构一体化设计与分析

Building structure integrated design and analysis of Wuhan Optics Valley E-sports Hall

武汉光谷电竞馆采用框架-剪力墙结构体系,为了实现荷载传递,结构中局部使用了钢斜撑、吊挂、托柱转换等结构形式。由于比赛大厅及建筑造型的影响,6层和屋面均采用大跨度钢桁架结构。建筑折面外表皮钢网格结构与主体结构采用一体化设计,从而达到结构与建筑形态的统一协调。本工程属于特别不规则的高层结构,运用多个计算软件对结构进行了静力弹性分析、弹性时程分析、中大震下的等效弹性分析和大震弹塑性分析。各项计算结果对比分析表明,结构满足预定的C级性能目标。最后,给出了本工程结构所采用的施工阶段分析步骤,并介绍了6层大跨度钢桁架典型支座节点设计、外表皮钢网格结构与内部混凝土结构的连接节点设计。

Wuhan Optics Valley E-sports Hall adopts frame-shear wall structure system,in order to realize load transfer,steel brace,hanging structure and column transfer structure were used locally in the structure.Due to the influence of the competition hall and architectural modeling,both the sixth floor and roof were constructed with large-span steel truss structures.The integrated design of the folded surface outer skin steel grid structure of building and the main structure achieves the unity and coordination of the structure and architectural form.This project belongs to a particularly irregular high-rise structure.Multiple calculation softwares were used to perform static elastic analysis,elastic time history analysis,equivalent elastic analysis under moderate and large earthquake,and large earthquake elastoplastic analysis on the structure.The comparison and analysis of the calculation results show that the structure can meet the predetermined C-level performance target.Finally,the construction stage analysis steps used in this project's structure were presented,and the design of typical support nodes of sixth floor large-span steel truss and the connection nodes between the outer skin steel grid structure and internal concrete structure were introduced.
