摘要:
为对比研究FRP管混凝土桩和钢管混凝土桩的黏结性能,进行了4组推出试验,分析了黏结方式、混凝土种类、试件长细比、外管壁厚等对黏结性能的影响.结果表明:相同试验条件下,钢管混凝土试件的黏结强度明显大于FRP管混凝土试件;使用膨胀混凝土、增大试件长径比及增大外管壁厚均可提高试件的黏结强度,但使用膨胀混凝土的提高效果最明显,可使其增大近10倍;不同的黏结方式下,应变随滑移量及截面高度的变化关系不同,对于直接黏结型试件,靠近荷载施加部位的应力首先发挥,而螺纹型试件的应变沿整个试件高度同时发挥.
Abstract:
To compare the bond performance of concrete-filled fiber reinforced polymer(FRP)piles and concrete-filled steel piles, 4 sets of push-out tests were conducted and the influence of the bond type, the concrete type, the thickness of pipes and the slenderness ratio on the bond performance were analyzed. The results show that under the same test conditions, the bond strength of the concrete-filled steel piles is much greater than that of the concrete-filled FRP piles. The use of expansive concrete, the increase of the slenderness ratio and the thickness of the pipe can improve the bond performance and the effect of using expansive concrete is the best, which can improve the bond strength up to 10 times. With different bond types, the strain of the pipes has different relationship with the slip and the height of sections. For direct bond specimens, the strain near the applied load first exerts, while for specimens with internal threads, strains exerts simultaneously along the entire height of the pipe.
