弹性楼盖结构建筑在抗震设计时,考虑纵向地震作用影响的处理方法比较粗略,计算系数的取值比较笼统,没有结合结构概念设计的思想来修正参数。该结构的纵向抗震计算,以往多采用屋盖为绝对刚性或绝对柔性的假定,忽略和掩盖了许多具体的应该考虑的因素。文章通过STRAT软件建立有限元模型,对规范计算假设和计算方法的分析,结合实结构概念设计思想,提出自己对传统计算方法的改进意见和建议。
In the seismic design of the flexible floor structure, considering the influence of longitudinal seismic action, the treatment methods are relatively rough, the values of the calculation coefficients are quite general, and the parameters are not modified according to the concept of structural concept design. Longitudinal seismic calculation of the structure, in the past often use the assumption that the roof is absolutely rigid or absolutely flexible, ignoring and masking many specific factors that should be considered. The article builds the finite element model through the STRAT software, analyzes the normative calculation hypothesis and the calculation method, and combines with the real structure concept design idea, proposes own improvement opinion and the suggestion to the traditional calculation method.
