Further, the actualcapacities of the structure may be inadequate in the face of real seismic demands. Althoughtwo records are never enough to make such generalization, it should be borne in mind thatthe latest revision of the code was released not long after these two earthquakes. Further, it isalso true that only a full probabilistic analysis can determinewhether these structures actuallyexceed the limiting collapse prevention probability, e.g., 2% in 50 years (SAC-FEMA 2000).Nevertheless, this study does underscore that a comprehensive investigation is in order andthat there is scope for rationalization in the IS codal provisions.Acknowledgments This work was produced as part of the undergraduate curriculum at IIT Kharagpur ofthe first author.

通过增量动态分析评估设计低层钢框架的IS 代码的规定

摘要:目前印度标准(IS)代码的结构抗震设计(IS1893:2002)指定的时间历程分析的结构高度大于40m。但是,对于结构小于40m的建筑建议采用等效的静态分析概念。本研究试图探讨当它涉及到低于40m的结构遭受地震加载指定的代码的静态分析,而不是使用动态分析,来实际评价目前的设计强度是否充足。增量动力分析,其主体结构为一个递增系列强度措施,出于此目标而采用了它。三种二维抗弯钢结构在1991乌德尔格希和2001普杰地震(这两个早于目前IS1893)已被研究,包括一个单一的多层门户框架、一个2层3跨框架和3层2跨框架。然而可以说,两个记录是远远不够总结任何结论的,只有一个完整的概率分析才可确定是否限制防坍塌的概率已经超过了这些结构,在两个代码的情况下才会显着预测出结构的抗震要求。与此同时,这也许就是为什么通常的规范规定,结构能力,在大多数情况下低估。这些建议是为了深入研究,并且IS codal的规定中有一些合理化的范围。 通过增量动态分析评估设计低层钢框架英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_56527.html
