The bearing capacity of the anchorage zone is involved in prestressed structures, which is a problem for the local compression zone. This paper used ABAQUS software to simulate the local compression of reactive powder concrete (RPC) under various conditions, according to RPC's deformation characteristics and mechanical properties. The damage parameters are filled in according to the constitutive model. The specimens with the duct have been simulated with different bearing plate lengths, stirrup spacing, and various reinforcement ratios and were studied. The load-displacement curves and ultimate bearing capacity were obtained. The summary and analysis showed that the stirrup spacing could provide a beneficial behavior in controlling the cracks. Moreover, the steel stirrup reinforcement can dissipate the energy in the specimen, and the RPC specimen's local compression bearing capacity is improved by increasing the bearing plate's length. |
