中文摘要：
纤维聚合物筋FRP（Fiber Reinforced Polymer）的耐腐蚀、抗拉强度高、重量轻、非磁性等特点使其在土木工程中的应用前景十分广阔．首先对我们自己研制的GFRP（Glass Fiber Reinforced Polymer）筋和CFRP（Carbon Fiber Reinforced Polymer）筋进行了常温下的受压试验，得到了GFRP筋和CFRP筋的抗压强度与抗压弹性模量；然后对GFRP、CFRP、CFRP与GFRP混合加筋混凝土短柱以及钢筋混凝土短柱进行了轴心受压试验，得到了加筋混凝土短柱的极限承载力、荷载-变形关系曲线、破坏形式和加强筋与混凝土的荷载-应变分布曲线，并将试验结果进行比较,结果表明：在没有约束的条件下，GFRP筋的抗压强度高于CFRP筋；在有约束的条件下，CFRP加筋混凝土短柱的抗压强度高于GFRP加筋混凝土短柱的抗压强度；FRP加筋混凝土短柱的抗压强度高于钢筋混凝土短柱的抗压强度；FRP加筋混凝土短柱的协同工作性和钢筋混凝土短柱的协同工作性相比较差。
英文摘要：
Fiber reinforced polymer bars have been introduced in civil engineering in term of noncorrosive, high Strengthto-weight ratio, nonmagnetic. Firstly, the experiment on the compressive properties of GFRP bars and CFRP bars was performed using the FRP bars developed test the compressive strength and the compressive modulus of elasticity. Secondly, the compressive experiment on concrete stub square column reinforced with GFRP bars, CFRP bars, two kinds of FRP bars and steel bars were performed. The ultimate load carrying capacity, load-deflection relationship, modes of failure and strain distribution was recorded respectively during the test. And the test results are compared. The results show that without the restrictied condition, GFRP bars have the superior compressive properties to CFRP bars. Under the restrictied condition, the ultimate load carrying capacity of CFRP bars reinforced concrete stub square column are superiorto concrete stub square column reinforced with GFRP bars. The ultimate load carrying capacity of FRP bars reinforced concrete stub square column are higher than the steel reinforced concrete stub square column. However, the cooperation of FRP bars with concrete are inferior to the cooperation of steel bars with concrete.
