对小开洞墙片侧移刚度计算的改进

Improvement in Lateral Rigidity Calculation of Wall with Small Opening

本文总结了目前我国砖墙墙片和钢筋砼墙墙片的侧移刚度计算方法和计算公式,叙述了国内对小开洞墙片侧移刚度计算的规定.在分析比较小开洞墙片侧移刚度计算数据的基础上,提出了对小开洞墙片侧移刚度近似计算公式的改进,以及对GBJ11-89规范第5.2.3条第一款的建议,供抗震设防计算参考.

This paper sums up the calculation methods and equations of lateral rigidity of brick wall and reinforced concrete wall in our country at present, relates the regulations of lateral rigidity calculation of wall with small opening.On the basis of analysis and comparison for lateral rigidity calculation data of wall with small opening, the improvement in lateral rigidity approximate calculation equations of wall with small opening is put forward. At the same time, the suggestion for the first item of entry 5.2.3 in code GBJ11-89 offers anti-seismic protection calculation to consult.
