摘　　要：以某石化工程10万吨/年聚丙烯项目中的干燥框架设计为例,通过对强轴方向梁柱采用刚性连接、弱轴方向梁柱采用铰接并设置垂直支撑,将双向梁柱采用铰接并设置垂直支撑的两种结构形式的优缺点和结构性能进行对比与分析,探讨了不同结构形式动力参数的合理性以及风荷载作用下结构的水平位移表现差异,对该类建构筑物的结构设计提出合理建议,同时对钢结构设计中常见的问题以及楼面荷载的取值、H型钢类别的选择等需要注意的事项进行了探讨和总结。Taking the design of drying frame in a 100000 t/a polypropylene project of a petrochemical project as an example,this paper compares and analyzes the advantages and disadvantages a1nd structural performance of the two structural forms of two-way beam column with hinge and vertical support by using rigid connection for beams and columns in strong axis direction and hinge and vertical support for beams and columns in weak axis direction,The rationality of dynamic parameters of different structural forms and the difference of horizontal displacement performance of structures under wind load are discussed,and reasonable suggestions are put forward for the structural design of such buildings and structures.At the same time,the common problems in the design of steel structures,the value of floor load,the selection of H-type steel and other matters needing attention are discussed and summarized.
