| 摘 要： | 本文首先建立了能包含均布侧向荷载、倒三角形侧向荷载、幂级数侧向荷载等常见侧向荷载的拟合二次曲线侧向荷载分布形式。推导了二次曲线侧向荷载分布作用下，框架-剪力墙结构的水平位移曲线。给出了以最大层问弹性位移角为控制量，确定二次曲线侧向荷载分布作用下框架-剪力墙结构所需的剪力墙数量的方法。最后给出的算例。证实了本文方法及公式的合理性，探讨了侧向荷载类型对所需剪力墙数量的影响。

| Abstract: | In this paper,a general lateral load pattern(e.g.quadratic lateral load pattern) which can include uniform lateral load pattern,triangular lateral load pattern and multimode lateral load pattern is set up,and the drift computation formula of frame-shear wall structure under the quadratic lateral load distribution is deduced.Then,a computation procedure of the shear wall quantity under different lateral load patterns is presented by using the maximum elastic interstory drift ratio as the criteria.At last,some numerical examples are given to verify the rationality of the proposed method and formula in this paper,and the influence of lateral load pattern on the shear wall quantity in frame-shear wall structure is discussed. |
