连梁屈服时双肢抗震墙结构的内力分析

根据双肢抗震墙在水平荷载作用下的破坏特点，在连梁中弯矩和剪力相对较大，以及强度设计中配筋往往出现超筋等情况，并假定在水平荷载作用下墙肢处于弹性阶段而连梁则达到极限状态时，导出了双肢墙的内力和位移计算公式，可用之计算任意楼层节点荷载、抗震墙厚度变化的双肢墙的内力和位移．

Analysis of Double Limb Shear Wall Structure fot the Linking Beams Being in the Limit Regime

According to the failure feature of the double limb shear wall under the action of horizontal loads,the relative greatness of the bending moment and shear force,and the situ-ation of excessive reinforcement arrangement during the strength designing as well as assum-ing that the wall limbs are in the elastic regime and the linking beams are in the limit reqime both under the action of horizontal loads,a formula for calculation of inner forces and defor-mation of the double limb wall is derived which can be used to figure out the inner forces and deformations of the double limb wall under arbitrary floor loads and with vatying thickness of the shear wall.
