摘要:
目前,国内各研究机构关于隔震设计过程中短期面压验算所采用的组合公式不唯一,各规范规程对此并未作详细规定。短期面压验算对隔震设计的安全性及隔震效果有很大的影响,采用不同的组合公式计算将有不同的结果。为给出一组最合理的组合公式来指导隔震设计,本文选取6个不同楼层数和不同设防烈度下的RC框架基础隔震结构作为分析对象,分别采用不同研究机构的组合公式计算支座的短期面压,并与三向罕遇地震时程分析所得的结果进行综合对比分析。结果表明:综合来看,采用文献8的组合公式计算求得支座的短期极大面压和极小面压与三向地震输入的结果最为接近,建议基础隔震建筑设计时采用此组合方式来验算短期面压。
Abstract:
At present, the combination formulas of calculating short-term surface pressure for different research establishments are different.There is no code in which given detailed provisions for it.The calculating short-term surface pressure has great effect on the safety, economical efficiency and performance of isolated structure.And different results are given by different combination formulas.In order to find a relatively reasonable combination formula for calculating short-term surface pressure, six isolated RC frame structures with different floors and fortification intensities are selected in the paper as examples.The short-term surface compressive stresses of these isolators are obtained by different formulas andtime-history analysis of three directionsunder rarely earthquake and they are compared with each other. These results show that the short-term surface pressure obtained by the formula from reference 8is the closest one to the result obtained by time-history analysis of three directions on the whole and the formula can be used in the design of isolated buildings.
