摘要

为了研究钢骨超高强混凝土（SRUHSC）柱-混凝土（RC）梁框架节点的地震损伤

在12个框架节点低周反复加载试验基础上

分析损伤发展规律。根据能量等效原理

以框架节点在外力所作功为初始总能量

建立了框架节点地震损伤定量计算方法

并对地震损伤指数增长规律进行了分析。分析了配箍率、轴压比、钢骨形式3种试验参数对地震损伤指数的影响。进而提出了SRUHSC柱-RC梁框架节点的地震损伤评定模型。结果表明:基于能量法建立的地震损伤指数和评定模型

能较好地反映在低周反复荷载作用下SRUHSC柱-RC梁框架节点的损伤状态

该结果可为此类结构的抗震加固修复提供理论参考。

Abstract

In order to study the seismic damage to steel reinforced ultra high strength concrete（SRUHSC）column and reinforced concrete（RC）beam frame joint

seismic damage rule were analyzed on the basis of experimental results of twelve frame joints under low cycle reversed load

the quantitative calculation method of seismic damage were put forward according to the energy equivalence principle

which was assumed that the initial total energy was the work done by the external force on the joints

and the increasing rule of seismic damage index was analyzed.The influence of three kinds of test parameters included stirrup ratios

axial compression ratios and steel bone forms on the damage index were evaluated.Then the seismic damage evaluation model of frame joints was put forward.The results show that the seismic damage index and evaluation model can well reflect the seismic damage characteristics of SRUHSC column and RC beam joints under low cycle reversed load.The research results can provide theoretical reference for the seismic strengthening repair of SRUHSC column and RC beam joints.
