摘　　要：针对铰支结构模型不能准确反映挑梁约束环境的实际受力状态,从挑梁截面承载力入手,分析了正常使用极限设计时挑梁尾部下部砌体中裂缝产生的原因,提出一种新的弹性支撑计算简图,可以较为真实地反映挑梁的实际工作状态。In view of shortages of hinged structural model, which can not correctly reflect the mechanical behaviors of cantilever beam this paper analyzes the reasons caused the cracks produced in foot part of cantilever beam under in limit service states from the normal section bearing capacity of cantilever beam. One simple drawing is proposed for calculation, which well reflects actual working states of cantilever beam.
