Abstract
Under the effect of vertical load and horizontal-low-cyclic load, the whole process of nonlinear finite element numerical simulation analysis of one specimen for bonded fully prestressed CFRP bar with mixed steel reinforcement frame-supported shear wall structure and one specimen for bonded partially prestressed CFRP bar with mixed steel reinforcement frame-supported shear wall structure were conducted. It analyzed the whole process of the structure from concrete cracks to transfer beam yielding until the damage of transfer beam. The analysis also included hysteretic characteristics and skeleton curves. It then studied the plastic strain of full and partially prestressed CFRP bars with mixed steel reinforcement frame-supported shear wall structures and their cracks development law, damage modes, load capacity, ductility performances and seismic performances.
