Abstract:The seismic design and seismic structural measures of light wood frame buildings were introduced through engineering examples. The horizontal seismic response of the structure was calculated by  using the base shear force method and the mode-decomposition response spectrum method respectively. The results show that this light wood frame building can meet the “three-level” fortification target of seismic design. The finite element models of several kinds of wood-based shear walls were compared. Based on the layered shell elements of SAP2000, the finite element model of the overall structure was established, and the dynamic characteristics, internal forces and deformation of the structures were calculated, which was used as the basis for seismic design. For the low ductility and high elastic bearing capacity of the light wood frame building, corresponding seismic structural measures have been formulated.

Keywords:light wood frame construction; seismic design; finite element analysis; seismic structural measures
