Abstract
In order to establish the systematic design method of performance-based earthquake engineering for steel-concrete hybrid structure tall buildings, a 1/15 scale model shaking table test is conducted in State Key Laboratory for Disaster Reduction in Civil Engineering of Tongji University. The dynamic property, acceleration and displacement response of the model structure under different earthquake levels are investigated from the test. The failure mode of structure is analyzed and the seismic response of the prototype structure is interpreted according to the similitude relation. The conclusions drawn from this investigation show that the prototype structure can basically satisfy the requirements of no damage under frequent earthquakes and no collapse under rare earthquakes; steel frame- concrete core structural system has good seismic performance under rare earthquake; and the damage of the connection between the steel frame beam and the core wall is the main failure pattern of the structure.
