摘要：
In order to investigate the seismic performance of structure with energy dissipation cladding panels (EDCP), a 1/ 2-scale two-story and one-span reinforced concrete (RC) frame structure was designed and fabricated. EDCP were only equipped along the Y-direction, forming a ‘damping structure’ in this direction and a ‘seismic structure’ counterpart in the X-direction. Two natural ground motions were selected as inputs, and unidirectional shaking table tests under service level earthquake (SLE), design basis earthquake (DBE), and maximum considered earthquake (MCE) were conducted in the two directions of the test structure. The dynamic properties and seismic responses of the two structures were then compared. The test results show that the damage degree and seismic response of the damping structure are lesser than those of the seismic structure under DBE and MCE, indicating a satisfactory control effect. The damage of the two structures both focuses on the ends of beams and the roots of first story columns, indicating that the EDCP does not influence the damage pattern of the main structure. Throughout the test, the U-shaped steel dampers exhibit an expected crawler-type deformation and basically keep undamaged. Even under MCE, the cladding panels remain intact, indicating that this kind of structure can effectively control the damage to the cladding panels. © 2023 Science Press. All rights reserved.
