底部框架-抗震墙房屋框架地震剪力的计算

CALCULATION FOR SEISMIC SHEARING ACTION OF THE BOTTOM FRAME-ANTI-SEISMIC WALL HOUSE FRAME WORK

对底部框架 -抗震墙房屋框架所承担的地震剪力计算方法进行了讨论。指出当底部只有一层框架 -抗震墙以及底部有两层框架 -抗震墙 ,但其抗震墙高宽比h b≤ 1时 ,框架承担的地震剪力可按各抗侧力构件的侧向刚度比例分配。而对于抗震墙 1<h b≤ 4的情形 ,框架所分配的剪力如仍按各抗侧力构件的侧向刚度比例分配 。

The calculation for seismic shearing action of the bottom frame\|anti\|seismic wall house framework is discussed.It was pointed out that while there only one story of frames in the bottom\|anti\|seismic wall,or two stories of frames in the bottom\|anti\|seismic wall,but the ratio of height to width of the anti\|seismic wall is not more than 1.0( h/b≤1 ),the seismic shearing force borne by frame shall be distributed by the proportion of the lateral rigidity of te anti\|sideforce components.For the anti\|seismic wall (1 <h<b ≤4),it shall result in a major error if the shearing force still be distributed by the ratio of the lateral rigidity of the antisideforce components.
