摘要
结合广东省某铁路旅客站房内部异型旋转楼梯的特殊布置,楼梯平面布局呈"直线段+圆弧线+直线段"的设计情况,充分利用空间力学原理,通过对杆件内力分析,寻求一种较为精确计算空间结构杆件内力的分析方法和思路。
This paper aims at the analysis and calculation for the internal force of dimensional lever on the basis of mechanics theory, which has been applied in the design of ＂one line, 90 degree circle and one line＂ stair of Tanshui railway station in Guangdong Province which has already been in use.
