中文摘要钢结构是目前世界上发展迅速并且应用广泛的建筑结构形式钢结构在中国将来成为最主要的结构形式已成为可能。目前探讨新农村的建筑形式是个热点本设计旨在为新农村的建设提出建筑方案设计了一11层的板式高层住宅结构方案采用钢框架。该建筑的同一个建筑方案采用了三种柱截面形式比较这三种方案的优缺点。为完成这项设计我做了以下工作。
确定建筑方案进行结构的分体系设计。采用平面结构分析模型选取一榀横向框架初选框架构件截面计算该榀框架的各种内力进行内力组合选取其中最不利组合验算结构的整体稳定性构件的承载力构件的稳定性。再进行节点设计选典型节点设计构件的连接方式验算节点的强度。设计出基础验算基础的承载力。本设计中采用H形钢柱再参考同组人采用箱型和圆钢管的柱截面的数据比较得出了如下结论用箱形截面柱和圆钢管截面柱的双向抗弯能力强但对于板式楼H形截面足以满足这些要求而且其用钢量较小对于塔式建筑来说H形截面柱就不合理其它两种截面较为适合。
