Analysis on Parameters of Wood-frame Model under Impact Loading

Deflection and stress of different cross section forms and its value are compared by finite element analysis of timberwork design model under the impact loading. The result indicates that decreasing the size of cross section or changing the section shape can effectively avoid the model too heavy and conservative design. In the case of horizontal loads applied on first floor, strengthening the column of first floor obviously reduces the deflection of model and improves the lateral stiffness. Keeping the column size of the first floor and choosing I-section significantly reduce the overall weight on condition of meeting the bearing capacity and stability, it also make the material higher utilization.
