摘要
给出了钢拱在一般荷载作用下的压弯相关公式,并通过对荷载条件、圆心角、不同截面放置方式等影响参数进行分析,验证了相关公式的安全性和适用性。
The interaction equation for the strength check against out-of-plane stability for steel arches subjected to combined bending and axial compressive actions is proposed. The buckling loads of arch with different load condition, subtended angle, manner of laying section are calculated by finite element method. The safety and applicability of the interaction equation is verified by parameter analysis.
