摘要

摘要: 为研究型钢再生混凝土短柱的抗震性能，对8个型钢再生混凝土短柱试件，采用悬臂柱式加载装置进行低周反复荷载试验，观察其受力过程和破坏形态。试验表明，剪跨比为1.4的型钢再生混凝土短柱以剪切斜压破坏形态为主；分别研究了轴压比、配箍率和再生粗骨料取代率对试件抗剪承载力的影响；分析了型钢再生混凝土短柱的受力特点和破坏机理；推导出型钢再生混凝土短柱发生剪切斜压破坏时的抗剪承载力计算公式。最后，为便于工程应用，在试验与理论分析的基础上，提出了型钢再生混凝土短柱抗剪承载力简化计算公式，计算结果与试验结果符合较好。

Abstract: In order to investigate the seismic behavior of steel recycled concrete short columns，eight specimens ofsteel recycled aggregate concrete short columns were tested under the low-cyclic reversed loading with the cantilevercolumn type equipment． The loading progress and the failure patterns of steel recycled aggregate concrete shortcolumns were observed during the test． The results indicate that the main failure pattern of steel recycled aggregateconcrete short columns with the shear span ratio of 1. 4 is mainly the shear compression failure． The influence of theaxial compression ratio，stirrup ratio and the recycled aggregate replacement rate on the shear capacity of specimenswas studied． The mechanism and failure feature of steel recycled aggregate concrete short columns were analyzed． Theformula for calculating the shear bearing capacity of steel recycled aggregate concrete short columns was deduced． Atlast，a simplified calculating formula for the shear bearing capacity of steel recycled aggregate concrete short columnswas put forward for engineering application． It is shown that the calculation results are in good agreement with the testresults．
