框架一密肋耗能复合墙结构与框架填充墙结构抗震性能的对比分析

用密肋耗能复合墙取代传统的砖墙作为框架结构中的填充墙，形成框架一密肋耗能复合墙结构．通过建立简化的刚架一整体钭压杆模型，运用静力弹塑性分析方法对框架一耗能复合墙结构与框架填充墙结构在周期、层间位移角、局部变形等几方面进行对比分析．计算结果表明，耗能复合墙通过优化设计即可调整抗侧刚度并能有效耗散地震能量，在中高地震烈度区以密肋耗能复合墙代替砖填充墙后，结构的抗震性能明显优于普通框架一砖填充墙结构．

Comparative analysis of seismic ribbed composite wall structure performance on frame-multi- and Infilled Frame Structure

A new structural system called frame-multi-ribbed composite wall structure is generated by using the multi-ribbed composite wall as the infilled wall in frame structure to replace the traditional infilled wall. The equivalent oblique compression bar model, suitable for multi-ribbed composite wall, is established for static elastoplastic analysis. Compared with the infilled wall, the calculating result of the static elastoplastic analysis for multi-ribbed composite wall on natural period, story drift angle, lo- calized deformation shows that such this kind of wall can raise the lateral stiffness of the structure and dissipate the earthquake energy. The seismic performance of frame-multi-ribbed composite wall struc- ture is much better than the infilled frame structure, especially on area with middle-high earthquake intensity.
