广州亚运城台球壁球综合馆空间造型复杂,下部结构为钢筋混凝土框架结构,屋盖为刚架-支撑体系的大跨度钢结构。主结构的支承体系在馆内分设箱形内环与空间桁架外环,有效过渡环内外不共面刚架,保证屋盖构件传力的有效性和连续性,同时在屋盖面内设置高强度合金钢拉杆以提高结构的整体稳定性,并对屋盖钢结构节点进行合理设计。对在恒荷载、活荷载、风荷载、温度及地震作用下的结构计算分析可知:本结构不属于风敏感体系,地震效应明显,较薄弱点出现在竖向构件中钢管混凝土柱底和局部主刚架支座处;大跨度钢结构的温度效应也非常明显,在结构中部设置温度缝可有效减小温度应力。
Guangzhou Asian Games City, squash and squash Hall Complex shape space complex, the lower part of the structure of reinforced concrete frame, roof rigid frame - support system for the long-span steel structure. The main structure of the support system in the museum within the box-shaped inner ring and space truss outer ring, the effective transition ring inside and outside the non-coplanar frame to ensure the validity of the roof member force transmission and continuity, while the roof surface set high Strength alloy steel rod in order to improve the overall stability of the structure, and the rational design of the roof steel structure node. The calculation and analysis of structures under constant load, live load, wind load, temperature and earthquake show that the structure is not wind-sensitive and the seismic effect is obvious. The weak point appears in the bottom of the CFST column and the local main Rigid frame support; temperature effect of long-span steel structure is also very obvious, set the temperature in the central structure of the seam can effectively reduce the temperature stress.
