　　AbstractLight wood-frame structure, as not only has good seismic performance, but also can give full play to its ligneous advantages such as light mass, high tenacity, energy saving and environment protection, is widely applied to low-rise buildings and villas. The rigidity and ductility of shear wall structured by wood-frame are closely related to its sheathing material and the nail layout. In order to give full play to the carrying capacity of the nailed connection nodes, the article adopts the finite element model to compare the stress distributions of sheathings with different nail spacing, and the carrying capacity of the connection at the point of the sheathing is destructed, and also to provide the reasonable value of nail layout and a reference for the actual structural design.
