Abstract:
In order to investigate the mechanical behavior of reinforced concrete short columns with steel fiber reactive powder concrete (RPC) columnpermanent template and the improvement effect of steel fiber RPC column-permanent template on bearing capacity of core reinforced concrete short column, axial compression tests on two square reinforced concrete short columns with steel fiber RPC column-permanent template of different wall thickness and a general square reinforced concrete short column used for comparison were carried out. The test results were verified using finite element model. According to the test and finite element analysis results, the axial bearing capacity calculation method of reinforced concrete short columns with steel fiber RPC column-permanent template was discussed. The results show that ultimate bearing capacity of reinforced concrete short columns is significantly improved by steel fiber RPC column-permanent template, and the yield of longitudinal reinforcement is delayed. With the increase of columnpermanent template thickness, axial deformation of reinforced concrete short column decreases, and the ultimate bearing capacity and ductility relatively increase. The lateral deformation of reinforced concrete short columns under axial compression is limited and axial deformation is decreased indirectly by column-permanent template. The finite element analysis results agree well with the test results. The calculation method can provide references for practical engineering.
