When a beam flange is coped at the connection, the lateralbucklingstrength 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 lateralbuckling and torsion.
