摘要：
In order to study effects of reinforcement measures proposed in "the code for structural design of mountainous buildings (draft for comments)" on the damage and failure mechanism of a frame structure supported by foundations with different elevations. Two 1: 8 scaled models for a 6-floor frame structure supported by foundations with different elevations were designed according to "GB 50010-2010 code for aseismic design of buildings" and "the code for structural design of mountainous buildings (draft for comments)", respectively. Their test phenomena and seismic responses were contrastively analyzed. Results showed that acceleration responses and their frequency spectra of models are closely related to the structure itself; after reinforcement, the load-bearing capacity of the structure is enhanced; with increase in earthquake intensity, effects of reinforcement on structural deformation are gradually significant, at last the deformation drops, and the deformation shape is no longer concave; after reinforcement, the damage of the structure part with different elevations is greatly reduced, the destruction level of upper grounding positions mitigated to some extent; the location of the maximum inter-story displacement angle shifts upward, and the damage degree of upper floors increases; after reinforcement, there is no significantly weak story, the structure has a better integrity. © 2020, Editorial Office of Journal of Vibration and Shock.
