Self-resetting coupled shear wall with replaceable coupling beam and bearing-energy dissipation capacity
The invention discloses a self-resetting coupled shear wall with replaceable coupling beams and bearing-energy dissipation capacity. Structural units of the self-resetting coupled shear wall comprise reinforced concrete self-resetting wall column units and novel replaceable coupling beam units. Wherein stirrups and distributed steel bars are arranged in the shear wall column, and the bottom of the wall column is connected with the constraint foundation beam; high-strength longitudinal bars are arranged at the two ends, close to the embedded columns, of the wall column correspondingly and serve as reset elements of the self-reset shear wall. Staged yield type metal dampers are arranged at the left wall foot and the right wall foot of the shear wall, and the dampers are connected with a foundation beam through end plates. In addition, a high-damping ECC material is adopted in a plastic hinge area at the bottom of the wall column, so that the energy dissipation capacity of the self-resetting shear wall is improved. The replaceable coupling beam unit comprises a viscoelastic damper and an I-shaped metal damper, and the replaceable coupling beam unit not only provides large lateral stiffness, but also has two-stage energy dissipation capacity, so that the self-resetting coupled shear wall structure has high bearing capacity and energy dissipation capacity.
本发明公开了一种带可更换连梁的兼具承载‑耗能能力的自复位联肢剪力墙，结构单元包括钢筋混凝土自复位墙肢单元和新型可更换连梁单元。其中剪力墙肢内部设置箍筋和分布钢筋，墙肢底部与约束基础梁连接；墙肢两端靠近暗柱处分别设置高强度纵筋，作为自复位剪力墙的复位元件。在剪力墙左、右墙脚处设置分阶段屈服型金属阻尼器，阻尼器通过端板与基础梁相连。此外，在墙肢底部塑性铰区采用高阻尼ECC材料，以提高自复位剪力墙的耗能能力。可更换连梁单元包括粘弹性阻尼器和工字型金属阻尼器，该可更换连梁单元不仅提供了较大的抗侧刚度，还具备两阶段耗能能力，从而使得自复位联肢剪力墙结构兼具高承载能力和耗能能力。
