摘要:
钢筋沥青隔震层施工简便、造价低廉,且具有较好的隔震性能,解决了广大村镇地区低矮房屋抗震能力普遍不足的缺点。但其工程设计方法尚不完善,如何进行隔震层弹塑性设计才能达到最好的隔震效果,目前尚不明确。本文介绍了钢筋沥青隔震层的构造,推导了隔震层竖向钢筋不发生第一类失稳和第二类失稳的条件,探讨了各设计参数的取值范围,提出了一种弹塑性设计思路:二阶段试算法。为便于该设计方法的应用,本文对一栋两层的砌体结构房屋进行了工程设计,验证该设计方法的适用性和可靠性。研究表明:合理使用该方法进行设计,水平减震系数可在0.5以下。
Abstract:
The steel-asphalt isolation layer construction is simple, low cost, and has good isolation performance, and it has solved the shortcomings of weak earthquake resistance of low buildings in the vast villages and towns. But its design method is not perfect, how to carry out the isolation layer of elastoplastic design to achieve the best isolation effect is not clear. In this paper, the construction of steel-asphalt isolation layer is introduced. The conditions for the first kind of instability and second kind of instability of the vertical reinforcement of the isolation layer are deduced, the range of the design parameters is discussed, an elastoplastic design idea is put forward:the two-stage trial calculation method. In order to facilitate the application of this design method, a two-story masonry building is designed to verify the applicability and reliability of the design method. The study shows that the horizontal seismic decrease coefficient could be controlled under 0.5 when using this method for design reasonably.
