中文摘要：

为了确定煤矸石骨料混凝土在建筑工程中应用的可行性和承受荷载的能力,对煤矸石骨料混凝土柱进行往复加载基础试验,获得不同轴压比下混凝土柱的滞回曲线、钢筋应力-应变曲线,并对其受力性能进行分析。结果表明,随着轴压比的增大,混凝土柱的变形能力及耗能能力都变差,轴压比超过0.6后,柱破坏较严重;混凝土柱结构应加强架立筋的配筋设计;试件柱的刚度及极限承载力随着轴压比的增大,增加幅度不大;其受力性能符合一般承重结构的发展过程,但在实际使用煤矸石混凝土时应控制轴压比不宜过大。

英文摘要：

In order to determine feasibility and the ability to bear loads of the light-weight aggregate concrete in construction engineering application,the reciprocating loading base experiment on the concrete column under axial compression ratio was carried out,whose hysteretic curve and steel bar stress-strain curve were got, and its mechanical performance was analyzed. The results showed that with the increase of axial compression ratio,the deformation capacity and energy dissipation capacity of concrete columns were worse; when axial compression ratio was more than 0. 6 the column destruction was serious. Concrete column structure support stud reinforcement design should be strengthened; column stiffness and ultimate bearing capacity of the specimens,with the increase of axial compression ratio increased slightly. Their mechanical properties conformed to the development of the general bearing structure,but should be controlled in the actual use of coal gangue concrete,axial compression ratio should not be too big.
