基于ANSYS模拟的无黏结预应力RPC简支梁分析

Unbonded prestressed concrete beams on ansys

活性粉末混凝土是具有超高抗压强度、高耐久性及高韧性等特点的一种新型超高性能混凝土材料。基于非线性有限元ANSYS软件,建立了无黏结预应力RPC简支梁的有限元模型,模拟了其在三分点加载下直到破坏的全过程,并将试验结果进行对比分析,两者吻合较好,可供设计参考。

Reactive Powder Concrete （RPC） is a new generation concrete material, compared with conventional concrete,it possesses excellent properties such as ultra-high strength,high toughness and high durability etc.Founds nonlinear finite element computational models, and imitates the loading until destructive process of the beams under one-third load on ANSYS, comparing with the experimental facts.They agreed well with each other, which provide effective basis for the evaluation of the bearing capacity.
