Abstract

Abstract

In-plane seismic performance of the reinforced reinforced concrete (RC) frame-cladding panel structural system after the earthquake was experimentally assessed herein. Two full-scale two-story seismic-damaged RC frames with different cladding panels were repaired by carbon fiber reinforced plastics (CFRP) sheets and steel plates. Quasi-static loading was imposed on the test specimens so as to comprehensively evaluate the bearing capacity, stiffness degradation, energy consumption capacity and failure patterns. Compared with the original structure, the horizontal shear forces of the two repaired structures were increased by 21.8% and 11.2%, respectively, when the inter-story drift ratios were 2.0%. The inter-story drift ratios were increased to 3.3% and 2.5%, respectively. The results showed that the repaired and reinforced cladding panel continued to provide support for the damaged RC frame under the rarely occurred earthquake as the second line of defence, and could improve the seismic performance of the strucatre. The enclosure wall could provide additional stiffness to the main structure under the rarely earthquake and slow down the stiffness degradation of the structure, which made the structure had better anti-collapse redundancy. Compared with concrete cladding panels, the connections of light steel-framed cladding panels were less damaged, which indicated that cladding panels with light weight could alleviate the seismic damage, improve the deformation capacity of the whole structure, and was easier to repair after the earthquake. The research results could provide scientific basis for the seismic performance of reinforced RC frame-cladding panel structural system after the earthquake.
