Micro-prestress self-resetting wall provided with self-resetting variable friction dampers and construction method thereof
The invention discloses a micro-prestress self-resetting wall provided with self-resetting variable friction dampers and a construction method thereof. The micro-prestress self-resetting wall comprises a foundation beam, a plurality of horizontal wall bodies arranged on the foundation beam and prestressed tendons penetrating through the horizontal wall bodies and the foundation beam and connectingthe horizontal wall bodies with the foundation beam, and variable friction dampers are arranged among the plurality of horizontal wall bodies and between the horizontal wall bodies and the foundationbeam for connection and fixation. The construction method comprises the steps that during construction, prestressed tendon channels are reserved on the foundation beam, middle friction plates are arranged on the foundation beam, inner friction plates or middle friction plates are arranged on the corresponding plurality of horizontal wall bodies, the plurality of horizontal wall bodies are connected and fixed, the horizontal wall bodies and the foundation beam are connected and fixed, and micro-tensioning is performed after the prestressed tendons are arranged. According to the self-resettingwall, under the action of an earthquake, the variable friction dampers arranged among the wall bodies and between the wall bodies and the foundation beam can consume a large amount of earthquake motion input energy through friction, self-resetting of the variable friction dampers can be achieved, and self-resetting force can be further provided to eliminate residual deformation of the wall bodiesin combination with arrangement of the prestressed tendons.
本发明公开了一种设有自复位变摩擦阻尼器的微预应力自复位墙及其施工方法，包括基础梁，设于该基础梁上的若干水平墙体，贯穿若干水平墙体及基础梁并将二者相连接的预应力筋，所述若干水平墙体之间以及水平墙体与基础梁间设置变摩擦阻尼器进行连接固定；施工时在基础梁上预留预应力筋通道并设置中摩擦板，在对应的若干水平墙体上设置内摩擦板或者中摩擦板，将若干水平墙体之间及水平墙体与基础梁连接固定，设置预应力筋后微张拉。该自复位墙在地震作用下，设于墙体间、墙体和基础梁间的变摩擦阻尼器不仅能够通过摩擦大量消耗地震动输入能量，且能够实现变摩擦阻尼器自复位，并结合预应力筋的设置，进一步能够提供自复位力消除墙体的残余变形。
