Title:
ENERGY-DISSIPATING REINFORCED CONCRETE SHEAR WALL HAVING RECOVERY FUNCTION AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/205336
Kind Code:
A1
Abstract:
An energy-dissipating reinforced concrete shear wall having a recovery function and a construction method therefor. The energy-dissipating reinforced concrete shear wall having a recovery function comprises a reinforced concrete shear wall body (21), and common vertically distributed steel bars (23) and common horizontally distributed steel bars (24) disposed therein. High-strength steel bars (22) are vertically disposed on the left and right sides of the shear wall. Four dampers are provided between the front and rear rows of reinforcement nets formed by the common vertically distributed steel bars (23) and the common horizontally distributed steel bars (24) in an X-shaped crossing mode. Cylindrical piston rods (31) having hinge holes at the ends of the four dampers are connected to diamond steel plate connecting rods (2) by means of movable hinges (1). The diamond steel plate connecting rods (2) are disposed in diamond connecting rod protective housings (4) with grooves (3) formed. The diamond connecting rod protective housings (4) are connected to connecting flanges (34) of the dampers. One ends of steel strands (5) are connected to the cylindrical piston rods (33), metal corrugated pipes (6) are disposed on the outer sides of the steel strands (5) and cylindrical piston rods (33), and the other ends of the steel strands (5) are anchored on the reinforced concrete shear wall by means of anchors (7). The shear wall has a recovery function, and also has high energy-dissipating capacity.
