免拆卸水泥复合模板-结构混凝土柱的轴心受压性能研究

Research on Axial Compression Capacity of Concrete Structure Column with a Cement Complex Formwork without Disassembly

通过对二根柱试件(一根免拆卸模板混凝土柱,一根普通混凝土柱)的试验,研究了免拆卸模板混凝土柱在单调荷载作用下的基本力学性能,包括破坏形态、极限承载力、柱侧混凝土应变、受力钢筋应变等,对免拆卸模板-结构混凝土柱与普通混凝土柱的受力性能进行了对比。实验结果表明:采用现行规范计算免拆卸模板-结构混凝土柱的极限承载力具有较高的安全性能;免拆卸模板-结构混凝土柱具有与普通混凝土柱相近的轴心受压性能。

Based on the experiment on two column specimens （one is a concrete column with a formwork without disassembly, another is an ordinary concrete column）, the basic mechanical properties of the concrete column with a formwork without disassembly under monotonic loading are studied, including failure patterns, ultimate bearing capacity, concrete strain, strain of reinforcing steel and so on. The comparison of mechanical behavior is made between the concrete structure column with a formwork without disassembly and an ordinary concrete column. The experimental results indicate that the ultimate bearing capacity of the concrete structure column with a formwork without disassembly has safer performance while using the current specification to calculate it, and its axial compression capacity is approximate to the one of an ordinary concrete column.
