Self-resetting double-column pier structure and construction method thereof
The self-resetting double-column pier structure comprises two column bodies, a bearing platform and a cover beam, the two column bodies are connected with the bearing platform and the cover beam through prestressed tendons correspondingly, the portions, connected with the cover beam and the bearing platform, of the two column bodies are each externally provided with a tension-only energy dissipation device, and the tension-only energy dissipation devices only bear tension under the action of earthquakes; a self-resetting energy dissipation supporting device is obliquely arranged between the two column bodies, and the self-resetting energy dissipation supporting device is hinged to the cover beam and the bearing platform. The unbonded prestressed tendons in the column body and the self-resetting energy dissipation supporting device are used for providing double self-resetting capacity for the structure, the self-resetting energy dissipation supporting device can further increase the overall lateral stiffness of the structure, and the purpose of reducing residual deformation is achieved by adopting the external tension-only energy dissipation device; the earthquake energy is consumed through the tension energy dissipation device and the self-resetting energy dissipation support together, installation is convenient, quick replacement is easy after damage, the structure can quickly recover the function after an earthquake, and the earthquake resistance toughness of the structure is improved.
本发明公开一种自复位双柱墩结构及其施工方法，包括两个柱体、承台以及盖梁，两个柱体分别通过预应力筋与承台和盖梁连接，两个柱体与盖梁和承台连接的部位均外设有仅受拉耗能装置，仅受拉耗能装置在地震作用下只受拉力作用，不承受压力，两个柱体之间倾斜设置有自复位耗能支撑装置，自复位耗能支撑装置与盖梁和承台铰接。本发明利用柱体内无粘结预应力筋和自复位耗能支撑装置为结构提供双重自复位能力，自复位耗能支撑还能增加结构的整体抗侧刚度，采用外置的仅受拉耗能装置实现减小残余变形的目的，通过仅受拉耗能装置和自复位耗能支撑共同消耗地震能量，便于安装，且受损后易快速更换，使结构震后能够快速恢复功能，提升了结构的抗震韧性。
