| 摘 要： | 湖北省图书馆新馆为框架结构,局部设置少量支撑及剪力墙,属于平面、竖向均不规则的结构。结合概念设计和计算分析,对新馆工程上托7层悬挑转换桁架的结构布置进行了设计方案比选;分析比较了不同楼板假定对桁架弦杆的受力和配筋影响。结果表明:传力越直接,结构布置越合理;对于平面不规则或考虑温度荷载工况的结构,刚性楼板假定会产生较大误差。桁架节点复杂,设计中提出了有别于常规做法的适用节点构造。

| Abstract: | The New Hubei Province Library mansion is a frame structure with a few braces and shear walls.It is an irregular structure both on plane and vertical direction.Combined with conceptual design and calculation analysis,a better structural scheme of the transfer cantilever truss which supports the upper seven floors has been chosen.The influence of different floor hypotheses on the stress of truss chords and the reinforcing bars was compared.The results indicate that the structure is more reasonable when the f... |
