摘   要：为了研究钢板-超高性能混凝土（UHPC）组合梁的抗弯性能，在钢板-UHPC-T组合梁方案下，以钢板厚度、钢板强度等级、UHPC抗拉强度和UHPC极限拉应变为参数，利用ABAQUS软件进行了有限元分析。结果表明：钢板厚度和钢板强度等级的改变对组合梁抗弯承载力的提高作用较为明显；UHPC抗拉强度的提高可以适当提高开裂荷载；UHPC极限拉应变的增加可适当提高梁体的延性。

Abstract: In order to study the flexural performance of steel plate-ultra-high performance concrete(UHPC) composite beams, under the plan of steel plate-UHPC-T composite beams, the finite element analysis was carried out with ABAQUS finite element analysis software, taking steel plate thickness, steel plate strength grade, UHPC tensile strength and UHPC ultimate tensile strain as parameters. The results show that the change of steel plate thickness and steel plate strength grade have obvious effects on the improvement of the flexural bearing capacity of composite beams. The increase of UHPC tensile strength can appropriately increase the cracking load, and the increase of UHPC ultimate tensile strain can appropriately improve the ductility of the beam.
