According to the requirement proposed by the Sixth National Structure Design Contest for college students (NSDCCS), a four-storey bamboo frame model raised floor house is built and experimented under a lateral impact load. The acceleration response is measured.and the FEA software LS-DYNA is used to carry out the finite element analysis to investigate the dynamic mechanism of the frame. The numerical simulation results are in a good agreement with the experimental acceleration time history curves. Furthermore, a parametric analysis is conducted to study the peak of the acceleration. The results indicate that the models with a higher initial relaxation offset of the tension rods or with a lighter contact plate will increase the acceleration of the frame. With regards to the mass of the impact ball, the velocity affects the peak of the acceleration more sensitively, and the peak acceleration increases with the increase of the ball velocity.
