摘要
我国抗震规范中填充墙对结构刚度影响考虑比较粗略,震害调查发现实际工程中由于没有充分考虑填充墙对结构刚度的影响,填充墙布置不当,使结构造成不应有的破坏。利用现有结构设计程序,可以充分模拟填充墙的刚度,使得填充墙刚度直接参与到结构的空间分析中,从而得到相对更为准确的设计数据。尤其是对结构底层柱水平位移的分析和层间位移的分析,在结构抗震设计中非常重要。
In China＇s anti-seismic codes,the consideration of the structural stiffness reinforced by the filled walls is relatively simplified,and the seismic damage surveys are found that the effect of the filled walls on the structural stiffness has not been fully taken into account,the improperly layout of the filled walls leads undue damage to structures.Using the existing design process of structure,the stiffness of the filled walls can be fully simulated.The stiffness of the filled walls is participated in the space analysis of structures directly,to obtain more accurate design data.In particular,analyses for the displacement of the bottom column and interstorey displacement are very important in the seismic design of the structures.
