混凝土箱型柱设计参数变化对其塑性变形能力影响的试验研究

Experimental study on influence of design parameter change on plastic deformation capacity of concrete box columns

钢筋混凝土箱型柱由于其闭合截面的特性,使其具有良好的空间受力性能,因而被广泛采用。为了研究设计参数变化对混凝土箱型柱变形能力的影响,在已有理论的基础上结合工程实际,设计了6个钢筋混凝土箱型柱试件。通过对其试验数据的分析,得出参数变化对钢筋混凝土箱型柱变形能力的影响。

Reinforced concrete box columns are widely used due to their closed cross-section characteristics, which makes them have good on the deformation ability of based on the existing theory spatial performance. In order to study the influence of the design parameters change concrete box columns, six reinforced concrete box column specimens were designed and engineering practice. Through the analysis of the test data, the influence of the parameter change on the deformability of the reinforced concrete box column was obtained.
