摘　　要：分析竖向荷载、风荷载、地震作用下框支剪力墙中框支梁的力学性能,表明框支梁截面高度对框支梁的力学性能影响很大,当框支梁截面高度不超过该梁净跨的1/7时,框支梁内力较小,且框支梁挠度及框支楼层的层间侧移均能满足建筑功能要求,这为框支梁的设计提供了实用的理论根据.In this paper, the mechanical properties of transforming beam in frame-supported shear wall subjected to vertical load, wind load and seismic action are analyzed. The result indicates that the height of transforming beam may have an extraordinary influence on mechanical properties of the beam. When the cross-section height of the beam may not exceed 1/7 of its net span, the internal force of the beam may be smaller, and the deflection of the beam and lateral displacement of supporting frame can satisfy the architecture requirements, which can provide practical theoretical basis for the design of beam.
