Numerical Simulation Research of the Laminated RC Shear Walls with Different Concrete Ages

The structural member quality can be effectively insured in factory, but the joints of the fabricated members are weak to actual load. A new partially prefabricated laminated wall is introduced here. To investigate the seismic performance of this kind of laminated wall, the specimens with and without opening were tested under inversed cyclic loading. Simulation program was performed by the general finite element program-ANSYS. The property of the interface of the prefabricated part and the cast-in-place part was investigated through the simulation. Research results indicate that: 1) the simulate results can agree with the test results using three-dimension springs to simulate the interface property; 2) the half prefabricated and half cast-in-place concrete laminated wall can coordinately work together fairly well.
