ABSTRACT

A novel integrated precast concrete (PC) structural system, which maximizes instead of minimizing the interaction between the PC sandwich cladding panel and main structure, is proposed through the introduction of U-shaped dampers. To systematically validate the feasibility and reliability of this system, a full-scale PC wall-frame substructure equipped with an energy dissipation PC sandwich cladding panel, as well as two dampers, were tested under the pseudo-static load. A refined simulation method is proposed and validated. The damage evolution mode, energy dissipation capacity, and failure mode of such a structure are identified, providing a foundation for further investigation of such structures.

摘要

通过引入 U 形阻尼器，提出了一种新型集成预制混凝土 (PC) 结构系统，该系统最大限度地而不是最小化 PC 夹层覆面板与主体结构之间的相互作用。为了系统地验证该系统的可行性和可靠性，在拟静载荷下对配备消能PC夹层板和两个阻尼器的全尺寸PC墙框架子结构进行了测试。提出并验证了一种改进的仿真方法。确定了此类结构的损伤演化模式、耗能能力和失效模式，为进一步研究此类结构提供了基础。
