Abstract：To study seismic behavior of lightweight bamboo frame residential house, shake table tests were conducted using a full-scale model, which simulated a first floor room unit of a typical two storey house, 2.44m by 3.66m in plan and 2.6m in height. Earthquake lateral resistance was provided by glubam shear walls around the perimeter of the model. The test results indicate that the model performed elastically and had essentially no visual damage for 0.3g PGA. The tested glubam house can withstand applications of three different seismic ground motions in the order of 0.5g PGA without collapse. The observed damage remained noncritical for 0.5g PGA. Inter-story drift in the first story was generally below most code required values. After subjecting shakings of 0.5g PGA, the model was retested under a pushover loading condition and showed sufficient deformability. The tests reveal that glubam house can meet the requirements for the seismic intensity of 8 as described in the China Seismic Design Code.
