Shaking Table Tests for a Full-Scale Model of a Steel-Timber Composite Structure

A shaking table test was performed by a full-scale two-storey model a steel-timber for composite house structure to investigate its dynamic characteristics and seismic behaviors. The test model was a light steel framed house whose size is 6.0 m and 5.0 m in plain and 6.4 m in height. Its dynamic characteristics and structural dynamic responses in different input seismic wave excitation were tested and analyzed. The test results indicated that the specimens performed elastically under the circumstances of 0.20 g PGA (Peak Ground Acceleration). The tested building model can withstand successive applications of different seismic ground motions and had no visual damages under the circumstances of 0.30 g PGA. The symmetrical ultra-light steel framed house specimen can meet the requirements for the seismic intensity of 8 as described in the Code for seismic design of buildings in China.
