Reactive powder concrete (RPC) has been widely used due to its high tensile and compressive strength and excellent durability. However, the failure mechanism of RPC local pressure is still unclear. Therefore, reasonable structural dimensions of the finite element model (FEM) and the relevant parameters of the RPC were selected to deeply explore the local pressure of the RPC under the local loading. The FEM of the axial local compression of the RPC with different constitutive models was built. The whole nonlinear analysis process of the local pressure of RPC was completed, and the failure mode, stress distribution, and maximum plastic principal strain of the specimen were analyzed. The model shows that the local pressure performance of RPC is improved due to the increase of ultimate tensile strength, the local pressure failure mode of RPC conforms to the wedge split theory, and the orthogonal ties can uniformly distribute the pressure stresses. |
