连梁屈服时多肢抗震墙结构的内力分析

根据多肢抗震墙在水平荷载作用下的破坏特点，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的情况，并假定在水平荷载作用下墙肢处于弹性阶段，而连梁达到极限状态，导出了多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、变厚度地的内力和位移。对抗震墙进行强度和刚度设计，发现更符合抗震墙破坏时的实际工作状态。

Analysis or Internal Forces in Multiple Limb ShearWall Structure with Yielding Linking Beams

Formulas for determination of internal forces and deformation of multiple limbshear wall are derived according to failure feature of the shear wall. excess of bending mo-ment and shear force in the linking beams.and excess of reinforcement in strength designingas well as assuming wall limbs being in elastic working state and linking beams being at plas-tic limit.The formulas can be used for determination of internal forces about linking beamsand wall limbs as well as the deformation of the shear wall under arbitrary floor loads andwith varying wall thickness.It is found that strength and rigidity designing of the shear wallby using the method presented conforms to real working pattern of the damage of the shearwall.
