| 摘 要： | GFRP管钢骨混凝土组合构件是由GFRP外管、钢骨和混凝土三部分组成.为研究组合构件的抗弯性能,进行了3根GFRP管钢骨混凝土试件的抗弯试验.采用纤维模型法编制非线性分析程序,以GFRP管壁厚度、混凝土强度、配骨率为主要参数,计算了9个构件,得到其弯矩与曲率关系曲线.结果表明:构件的抗弯承载力随着混凝土强度的增加而增大,随着GFRP管壁厚度的增加而增加,且变化幅度相对明显.采用统一理论方法建立构件抗弯承载力计算公式,并通过试验进行验证,理论计算结果与试验结果吻合良好.

| Abstract: | A GFRP tube in which a RC column is filled in is proposed as a new type of composite member. The member consists of an outer tube made of glass fiber reinforced polymer (GFRP),steel bars,and inner concrete. Bending tests were conducted with three specimens to investigate their flexural behavior. Based on the fiber model,a nonlinear analysis was programmed with the wall thickness of GFRP tube,concrete strength and percentage of reinforcement as principal parameters so as to calculate 9 members,thus obtaining... |
