000012347 520__ $$2eng$$aAn efficient hybrid structural system is obtained when reinforced concrete (RC) core walls are used in conjunction with steel perimeter frames. Core walls can be effectively formed by coupling individual wall piers with the use of coupling beams. Outrigger beams are framed between the core walls and columns in the perimeter frame. The successful performance of such one-tower hybrid structural systems depends on the adequacy of the primary individual components which are the core walls, steel frames, and frame-core connections. For the multi-tower hybrid structures, the problem becomes more complex. A multi-tower RC core wall-steel frame hybrid structure, rigidly connected at the middle height of the building, was thus introduced in this paper. A 1/15 scaled model structure was tested on the shaking table at Tongji University. Earthquake records of El Centro and Pasadena, local accelerogram of Shanghai Wave II, and the white noise were sequentially input to the shaking table under frequent, basic, and rare earthquake intensities. In the experiment, the structural damage was observed and the stress, acceleration, displacement responses were recorded. Then, the dynamic responses of the model structure were interpreted to the seismic design of the prototype structure. It was concluded that the torsional effect of the multi-tower structure was so obvious that those walls at the corner of the floor plan cracked first. The largest inter-story drift happened at the connected truss story, where buckling of the steel members was observed. Some suggestions to the structural design of the multi-tower hybrid structure were also given.
