平湖文化馆主楼前厅外挑16.8m,竖向承重体系不能连续,通过结构方案对比,工程设计中根据建筑外形特点采用六榀钢筋混凝土斜腹杆桁架,实现结构受力与建筑外形要求的统一。运用SATWE和MIDAS/GEN两种不同有限元模型软件进行对比分析校核,保证大跨外挑桁架结构的安全性与可靠性。观众厅屋面跨度25.2m,采用钢-混凝土组合结构,通过在支座处混凝土楼板设置施工后浇带,释放端部弯矩,避免出现支座裂缝。
Outside the main hall of Pinghu Cultural Center, the external load is 16.8m. The vertical bearing system can not be continuous. Through the comparison of structural schemes, the truss of six-girder reinforced concrete inclined webs is adopted in engineering design to achieve the uniform requirements of structural stress and building shape. Using SATWE and MIDAS / GEN two different finite element model software for comparative analysis of checking, to ensure the safety and reliability of the long-span pick truss structure. Auditorium roof span of 25.2m, the use of steel - concrete composite structure, through the concrete floor slab set after construction pouring zone, the release of the bending moment to prevent the occurrence of bearing cracks.
