针对国家高规和广州高规关于框剪结构0.2V0剪力调整中对框架梁调整规定的不同进行了多角度分析;采用PKPM-SAUSAGE软件对一些普通工程算例进行有针对性的弹塑性动力时程分析。结果表明,若对框架梁不进行0.2V0剪力调整,罕遇地震作用下,在柱、墙及柱、柱之间协同工作性能较好的情形下可减小框架柱和剪力墙的地震剪力,并减小结构层间位移角;在其他情况下,对框架柱和剪力墙的地震剪力及结构层间位移角的影响很小;在目前规范条文限制下,建议采用广州高规的做法或者采用经验做法对框架梁的剪力调整系数进行控制。
Aiming at the different adjustment regulations of the frame beam in the 0.2V0 shear adjustment of the frame-shear structure of the state high gauge and Guangzhou gauge gauge, the PKPM-SAUSAGE software is used to carry out targeted elasto-plastic motions on some common engineering examples Time history analysis. The results show that if the frame beam is not subjected to 0.2V0 shear adjustment, the earthquake of frame columns and shear walls can be reduced under the condition of rare earthquakes with better coordination performance among columns, walls, columns and columns Shear force, and reduce the displacement angle between structural layers. In other cases, the influence of seismic shear force and displacement angle between structural columns and shear walls is small. Under the current restrictions, it is suggested that Guangzhou high The rules of practice or the use of empirical methods to adjust the frame beam shear adjustment coefficient.
