顺昌博物馆结构设计

Structural design of Shunchang Museum

顺昌博物馆是一座采用框架-剪力墙结构体系的公共建筑。博物馆主体包括东、西两栋建筑,两栋建筑通过一个由两片曲面桁架及中心圆环构建的通道空间相连。结构除存在扭转不规则、楼板不连续外,还存在大跨度、连体情况,利用楼板刚度大的特性设计了支撑于不同楼面高度的桁架,满足了建筑对空间的要求。采用YJK软件对结构进行整体计算,各项指标均满足现行规范要求。针对该工程特点及结构设计难点,进行补充分析,主要包括关键构件的力学计算、楼板应力分析、考虑桩弯曲刚度与不考虑时结构内力对比分析。计算结果表明,该结构安全可靠,有效解决了侧推力的问题。

Shunchang Museum is a public building with frame-shear wall structure.The main body of the museum consists of east and west buildings,which are connected by a passageway space constructed by two curved trusses and a central ring.In addition to irregular torsion,floor discontinuity,the structure also has large span and jointed structure.The trusses supporting different floor heights were designed by taking advantage of the characteristics of high floor stiffness,which meets the requirements of building space.YJK software was used to calculate the whole structure,and all the indicators meet the requirements of the current code.According to the engineering characteristics and structural design difficulties of the project,the supplementary analysis were carried out,mainly including the mechanical calculation of key components,the stress analysis of floor,and the comparative analysis of structural internal forces with or without the consideration of pile bending stiffness.The calculation results show that the structure is safe and reliable,and can effectively solve the problem of side thrust.
