摘要

现浇框架结构,梁采用矩形梁(梁采用不放大刚度和放大刚度两种)及T形梁(梁采用不放大刚度)用三种方式进行抗震计算,比较位移角、周期、剪重比及梁柱配筋,提出位移角及梁柱配筋可按不同梁刚度计算采用,并利于实现"强柱弱梁"破坏机制。
There were three methods for the beam's aseismatic calculation in the cast-in-place frame structure which were adopted rectangular or T-shape for the beam and amplified the beam's stiffness coefficient.Calculation and compare the displacement angel,natural vibration period,shear-weight ratio and reinforcement ratio of beams and columns the structure were done.The results show that the displacement angel and reinforcement ratio of beams and columns can be got according to the beam's stiffness and realize the strong column weak beam failure mechanism.
