Abstract

Abstract

In order to improve the aseismic performances of Chinese traditional dwellings constructed with rowlock walls, the high ductility cement-based composite (ECC) was used to strengthen the two sides of the walls, and the reinforcement schemes could be divided into frame plastering reinforcement, framed cross-plastering reinforcement and full plastering reforcement. A total of 4 walls were fabricated and studied by quasi-static tests. The effects of different reinforcement schemes with ECC were studied, and the failure mechanisms and aseismic performances of different reinforcement schemes were analyzed. The test results showed that the bonding properties between ECC and rowlock walls were good, ECC and rowlock walls could resist horizontal load cooperative. The bearing capacity, deformation capacity and energy-dissipation capacity of walls strengthened with ECC were improved. The frame-plastering reinforced wall showed the best ductile deformation capacity and larger initial stiffness. The framed cross-plastering reinforced wall showed the best energy-dissipation capacity and the best hysteretic characteristics. The full plastering-reinforced wall showed the best bearing capacity and higher cracking capacity. The three reinforcement schemes had different advantages and could be selected according to needs in the actual engineering.
- rowlock wall,
- energy-dissipating capacity,
- quasi-static test,
- seismic performance,
