| Abstract: | This paper presents an experimental analysis of energy dissipation and seismic property of a high-strength concrete structure reinforced with pre-stressed rebars.A pseudo-dynamic experiment on 1/2 scale model with two floors and two bays is conducted in the laboratory,focusing on the analysis of hysteretic responses and energy dissipation capacity of the structure under seismic action,and a discussion is had on the damage mechanism,hysteretic property and weak locations or parts of the structure.The experim... |
