1、基本资料

1.1、建筑物基本资料

1

某单层单跨钢结构厂房长度150m，檐口高度：7500mm，基础顶埋深：800mm，柱距：7500mm，跨度：15000mm，屋顶坡度0.1。如图0框架立面图。

1.2、设计荷载

恒载：0.3KN/m，风载：0.4KN/m，活载：0.5KN/m，不考虑抗震设防。

2222、内力图

用力学求解器计算这种荷载作用下的门式钢架内力，并经最不利组合得出的弯矩包络图，剪力包络图，轴力包络图如下所示。

图3轴力包络图 （单位：KN）

3、钢材级别和梁柱截面

本门式钢架采用碳素结构钢，牌号表达为Q235钢。经PKPM软件计算得出钢材截面。由图2可知截面大小，梁采用焊接H型钢HM234×180×6×8，柱采用焊接H型钢HM480×250×6×8。
