摘要

为探究不同抗侧刚度全再生钢管混凝土框架抗震性能,进行了2榀不同柱截面尺寸全再生钢管混凝土框架的低周反复加载试验,观察了试件的破坏过程及形态,并获取其抗震性能指标。结果表明:全再生钢管混凝土框架滞回曲线饱满,当达峰值及破坏点时,其等效黏滞阻尼系数he明显大于钢筋混凝土及钢筋再生混凝土框架,表现出良好的弹塑性耗能性能;随着柱截面尺寸增加,试件承载能力、耗能性能及抗侧刚度均呈现出上升变化走势;随着加载位移增加,试件损伤程度逐渐增大,并且正向损伤程度要大于负向;正向加载时,试件损伤指标d随着柱截面尺寸增大而增大,而负向加载时,试件d随着柱截面尺寸增大而减小;最后,基于D值法计算模型及不同规程,对试件抗侧刚度的计算与试验值进行了比较。对全再生钢管混凝土框架,其在开裂荷载时的抗侧刚度可基于D值法计算模型,并按规程CECS的规定来进行计算。

Abstract

Here, to explore seismic performance of recycled aggregate concrete filled steel tubular frames with different lateral stiffness, the low-cycle repeated loading tests of two recycled concrete filled steel tubular frames with different column section sizes were conducted to observe failure process and morphology of specimens and obtain their seismic performance indexes. The results showed that hysteretic curve of a recycled aggregate concrete filled steel tubular frame is full, when it reaches peak value and failure point, its equivalent viscous damping coefficient he is significantly larger than those of reinforced concrete (RC) and recycled RC frame, it has good elastic-plastic energy dissipation performance; with increase in column section size, load-bearing capacity, energy dissipation performance and lateral stiffness of specimens have upward trend; with increase in column section size, shear strength of specimens increases; with increase in loading displacement,  specimen damage degree increases gradually, and damage degree in the positive direction is larger than that in the negative direction; when loading in the positive direction, the specimen’s damage index d increases with increase in column section size, when loading in the negative direction, the specimen’s damage index d decreases with increase in column section size; the calculation results of specimen lateral stiffness based on the D-value method calculation model and different regulations are compared with test ones, they are basically consistent; the lateral stiffness of recycled aggregate concrete-filled steel tubular frame under cracking load can be calculated based on D-value method and according to the regulation CECS.
