摘  要:
为了研究方钢管再生混凝土短柱的力学性能,在考虑再生骨料取代率、偏心距2个变化参数的基础上,设计了15个试件进行单调一次加载试验。利用ABAQUS有限元分析软件计算方钢管再生混凝土短柱不同影响因素下的极限承载力,并提出方钢管再生混凝土短柱轴压和偏压承载力计算公式。结果表明:理论计算结果与试验实测结果吻合较好。

摘  要:
To study the mechanical properties of recycled aggregate concrete-filled square steel tube(RACFSST)short column,15 RACFSST short column are designed,and take into account the replace rate of recycled aggregates,eccentricity 2change parameters.The ultimate bearing capacity of RACFSST short column for different parameters is calculated by ABAQUS,so as to propose formula of RACFSST axial and bias compression bearing capacity.The results show that the formula value of axial compression and bias short column is good agreement with the test results.
