When a beam flange is coped at the connection, the lateral buckling strength of the coped beam could be significantly less than that predicted by current formulas.
在切去梁翼后(简称切口)梁的侧向屈曲强度会比通常采用的设计理论所计算的强度大大降低。
The purline is often designed as a simple beam, and only it′s strength needs to be calculated, if the roof panel can prevent it′s lateral buckling and torsion.
檩条一般采用简支梁，假定屋面板能阻止其侧向失稳和扭转，则只计算其强度。
