Based above , a two - grade fuzzy comprehensive evaluation model is presented on the ground of the current seismic design code for building . it is that taking the membership of equivalent shear velocity as weight of the model not empirical weight in traditional one - grade model . it has been proved in site classification reasonable 参照我国现行建筑抗震设计规范,改变过去以经验系数为权重的一级模糊综合评判模型,以等效剪切波速对各场地土的隶属度为权重,建立了场地二级模糊综合评判模型,对场地进行划分。
Chinese seismic design code has adopted the popular seismic design concept in the world , that is , using reasonable combination of " seismic design force - ductility grade " and the concept of " capacity design " to set up an ideal energy - dissipation mechanism behaving inelastic dynamic response characters to resist given seismic intensity 中国建筑抗震设计规范采纳了当今世界各国主流的抗震设计思想,即以合理的“设计地震力- -延性等级”的组合和“能力设计( capacitydesign ) ”的思路来构架具有合理的非线性地震响应特征的耗能机构抵御预定水准的地震作用。
( 4 ) the failure correlation of beam end and column end under " minor earthquake was analyzed by monte carlo simulation method . based on this , a reliability analysis method for reinforced concrete frames with good conceptual design under " minor earthquake " is presented ( 4 )采用montecarlo模拟法,分析了按现行建筑抗震设计规范设计的钢筋混凝土框架结构在“小震”作用下,梁端和柱端控制截面的失效相关性,进而提出框架结构在“小震”作用下的可靠度分析方法。
According to the demand of 《 code for seismic design of building 》 ( gb50011 - 2001 ) , furthermore , based on the experimental study of two 1 / 15 reduced - scale shear wall models under low frequency cyclic and reversed lateral loads , the interacting behavior of the r . c frame column and the shear wall is studied , the failure mechanism and energy dissipation mechanism of moderate and tall shear wall with r . c frame column are compared , the seismic behavior is evaluated by the comparison of strength , stiffness , ductility , restoring force characteristics as well as energy consumption ability . it was showed by the experimental results that the earthquake resistant energy dissipation ability of the shear wall with frame column is satisfactory 因此,为了探讨这类剪力墙结构的抗震性能,本文以我国现行《建筑抗震设计规范》 ( gb50011 - 2001 )的要求为基础,通过1 15的缩尺比,将一纵向框架一剪力墙原型结构中的剪力墙结构模拟为一个试验模型并对其进行了伪静力加载试验,研究了墙板与边框柱的共同工作性能,分析了带边框柱中高剪力墙的受力特点、破坏及耗能机理,并从承载力、刚度、变形、延性及恢复力特性等方面综合评价了其抗震性能,得出了一些有益的设计理念和方法。
