| 摘 要： | 由于新旧材料强度不同,以及应力、应变的不一致性,使得增大截面后的柱无法简单地当作新建构件进行抗震验算,设计师常用的设计分析软件也没有提供混合强度材料构件共同作用的构件定义。本文分析研究了柱增大截面后参与整体结构设计的相关因素,对比了传统的简化算法与精确算法的差异,并提出一种将混合强度材料的构件折算为单一强度材料构件截面换算方式,为工程师在加固设计时考虑加固后构件参与整体结构抗震验算提供参考依据。

| Abstract: | There are problems that complicate the seismic design because elements with hybrid concrete are barely available in popular designing tools.In this paper,problems associated with SEM were discussed as well as the influences of the factors on stiffness when the retrofitted elements were subjected to overall aseismic design.Comparisons of stiffness have been made between the conventional and the precise method.Then a novel conversion method is proposed to transform the size of section into one that can stand ... |
