钢骨混凝土柱轴压比限值的研究

Study of limit values of axial compression ratio for steel reinforced concrete column

从钢骨混凝土受压柱延性破坏的角度出发,利用平截面假定、平衡条件推导钢骨混凝土柱轴压比限值的计算公式,并同钢筋混凝土的轴压比限值进行比较,提出在不同抗震等级下的钢骨混凝土柱轴压比限值。

The theoretical calculation formulas of limit values of axial compression ratio for steel reinforced concrete column based on the balanced condition of internal forces and the supposition of plain section in the case of ductile failure are derived. Compared with reinforced concrete,the limit values of axial compression ratio are given in various seismic behavior.
