摘要
本文针对高温对钢筋混凝土结构植筋锚固性能的影响进行了试验研究。通过植筋边节点构件高温时在反复荷载作用下的抗震性能试验,得到P-Δ曲线和钢筋的最大应变值,分析了高温对植筋边节点结构抗震性能的影响,提出了温度(焊接温度和高温200℃和300℃)对植筋结构锚固性能的影响,并给出合理的施工建议。
In this paper, the experimental study about the seismic performance of post-embedding bars in RC structures in high temperature is carried out. Based on the test of post-embedding bars exterior joints under cyclic loading, p-△ curves and the maximum strains value of bars are derived, and the influence of high temperature upon the seismic performace and anchorage performance of post- embedding bars exterior joints are analyzed. It could provide some references for construction.
