Lead viscoelastic steel bar bending-pulling deformation conversion self-resetting energy dissipation support
The invention provides a lead viscoelastic steel bar bending-pulling deformation conversion self-resetting energy dissipation support. The energy dissipation support comprises an elastic resetting system arranged between a left loading control device and a right loading control device and mixed energy dissipation systems located on the upper side and the lower side of the elastic resetting system and symmetrically arranged; each mixed energy dissipation system comprises a viscous-elastic material arranged between an outer constraint steel plate and an inner shear steel plate, and a lead core and an energy dissipation steel bar which penetrate through through holes of each outer constraint steel plate and each inner shear steel plate; the joints of each outer constraint steel plate and each inner shear steel plate are connected through bolts, and the two ends of each energy dissipation steel bar are tightened through nuts internally provided with spring washers; and each outer constraint steel plate and each inner shearing steel plate are connected in a herringbone shape, and each outer constraint steel plate and each inner shearing steel plate are hinged to the left loading control device and the right loading control device respectively. The energy dissipation support has the performance characteristics of a lead viscoelastic damper and a metal damper, the energy dissipation capacity of the energy dissipation support can be improved by adjusting the herringbone included angle, and residual deformation of the structure can be effectively reduced through the support.
本发明提供一种铅粘弹性钢棒弯‑拉变形转换自复位耗能支撑，包括设置在左加载控制装置、右加载控制装置之间的弹性复位系统和位于弹性复位系统上下两侧且对称设置的混合耗能系统；混合耗能系统包含布置于所述外约束钢板与内剪切钢板之间的粘弹性材料及穿过所述外约束钢板和内剪切钢板通孔的铅芯和耗能钢棒；所述外约束钢板和所述内剪切钢板的连接处通过螺栓连接，耗能钢棒两端通过内设弹簧垫片的螺母拧紧；所述外约束钢板和所述内剪切钢板呈人字形连接，所述外约束钢板与所述内剪切钢板分别与所述左、右加载控制装置铰接。本发明兼具铅粘弹性阻尼器和金属阻尼器的性能特点，调整人字形夹角可提升其耗能能力，该支撑能够有效降低结构的残余变形。
