Abstract:
A new connection method using metal corrugated pipe to reserve through-holes in precast shear walls was proposed. Low-cycle reciprocating loading tests on three shear walls were carried out to observe the whole failure process of corrugated pipe through-hole shear walls under horizontal cyclic loading. The hysteretic characteristics, failure modes, ultimate bearing capacity, structural ductility, energy dissipation capacity and longitudinal reinforcement strain of this type of shear wall were analyzed. The results show that the damage forms of precast concrete corrugated pipe through-hole shear walls are characterized by shear-compression failure and the hysteretic curves are relatively full. The walls have better performance in energy dissipation capacity and ultimate bearing capacity and good seismic performance. The overall strength and stiffness of the shear wall can be improved by filling the corrugated pipe with high-strength grouting material. The longitudinal bars at both ends of the wall are the key to the bearing capacity of the shear wall. To ensure the continuity of the steel bars at the edges of both ends, for the convenience of construction, the longitudinal bars in the middle of the wall are not disconnected at the same height, which has little effect on the bearing capacity of the corrugated pipe through-hole shear wall. It provides a scientific basis for the design and construction of precast concrete corrugated pipe through-hole shear wall.
