GFRP空心柱与约束混凝土实心柱侧向受压试验研究

Experiment Research about Lateral Bearing Capacity of Hollow Column and Concrete Column Which is Restrained by GFRP Pipe

本文主要对课题组所做的GFRP空心柱与约束混凝土实心柱侧向受挤压试验进行综述。详细介绍整个试验,包括试验的材料,仪器设备,主要的步骤,实验现象,数据处理与理论计算,通过应变箱和位移计测得在不同荷载下点的位移和应变,绘出荷载与位移,荷载与应变的曲线图,并且对试验结果进行了分析,分析试验中端部不符合应变规律的现象,比较同一管径同一纤维纵横比空心柱与混凝土实心柱的受力性能,同一管径不同纤维纵横比空心柱之间的力学性能。

This paper introduces experiment research about lateral bearing capacity Of hollow column and con- crete column which is restrained by GFRP pipe. The whole experiment is introduced in detail, including rnateriai, e- quipment, experimental procedure, experimental phenomenon, and data processing. Diagram of load and displace- ment,load and strain is eruved, and the test results are analyzed. The mechanical properties of the same diameter of the same fiber in the hollow column and the concrete column are compared. The mechanical properties of the same diameter of different fiber and the hollow columns are compared.
