摘要
对四根分别布置12mm、14mm、16mm和18mm非预应力钢筋的混合配筋高强混凝土管桩进行低周往复加载试验,对各试件的承载能力、延性、极限弯矩进行了分析。研究了不同直径的非预应力钢筋对PHC管桩的抗震性能影响,并使用ANSYS建立管桩模型,对试验进行模拟,结果表明当间隔布置的非预应力钢筋直径为16mm时,管桩试件的位移延性系数最大,其抗震性能最好。
The lest of 4 hybrid nonprestressed reinforced high strength concrete pipe pile which respectively arranged 12,14,16and 18mm under low cyclic loading is carried out. The effects of PHC pipe pile of different diameters on the seismic performance of non-prestressed reinforcement is studied. The numerical simulation of the tests is conducted by using ANSYS. The results ter of non-prestressed reinforcing bar is 16mm, the displacement ductility performance is best. indicate that when the diame- factor is largest, the seismic
