五螺箍钢筋混凝土柱的力学性能试验研究

Experimental Study on Mechanical Properties of Five-screw Hoop Reinforced Concrete Column

为对比五螺箍钢筋混凝土柱和普通复合箍筋钢筋混凝土柱在轴心受压、偏心受压和抗剪这三方面的力学性能,设计了6个钢筋混凝土柱试件,进行力学性能试验。试验结果表明:五螺箍钢筋混凝土柱的轴心受压承载能力约为普通复合箍筋钢筋混凝土柱的1.123倍,其延性和抗剪承载能力也更为优秀,两者的偏心受压性能则较为接近。

This work compares the mechanical properties between the five-screw hoop reinforced concrete column and the ordinary composite hoop reinforced concrete column in three aspects of axial compression,eccentric compression and shear resistance.Six specimens of reinforced concrete column were designed for mechanical properties test.The test results show that the axial compression bearing capacity of the five-screw hoop reinforced concrete column is about 1.123 times that of the ordinary composite hoop reinforced concrete column,and its ductility and shear bearing capacity are also better,while the eccentric compression performance of the two is relatively close.
