Background
The concrete material that present building industry is commonly used is great to the pollution of environment, and the sustainability is relatively poor, and the dead weight is also great, and materials such as timber, steel are of small quality, intensity is high, green can circulate, therefore the application of materials such as timber, steel in the building is constantly promoted in recent years in the country, and the trade also has important demand to the new building structure form of constituteing by these green materials. Most of traditional wood structure columns are solid and log materials, and the cross section of the columns cannot be made large due to limitation of materials. Modern timber structure combines the characteristics of traditional timber structure, begins to adopt veneer lumber and steel as the material, and the application of veneer lumber has alleviated the material anisotropy, the inhomogeneous condition of log to a certain extent, and steel is because light in weight excels in, the ductility is good, can effectively alleviate the damage and the destruction of timber structure post node department, and veneer lumber and steel all can be prefabricated simultaneously, can significantly reduce construction period.
