The paper select a model of beam-column joints of apparent storeys to simulate, and a similar material which is called larch.
Generally, the difference in radial and tangential of wood is ignored, so the properties of radial and tangential of anisotropic materials are same in models [3].

When two or more materials with different properties are combined together, they form a composite material [2-3].
The properties of composite materials, in general, are superior in many respects to those of the individual constituents.
This has provided the main motivation for the research and development of composite materials.
In our research, amphoteric vinyl-polymer/ZnO nano composite (PDM/ZnO) was prepared using DMDAAC, acrylic acid, 2-hydroxyethyl acrylate, acrylamide as raw materials.
The resultant leather samples were put into an air conditioner for 48 h, and the tensile and tearing strength of the leather were tested with a GT-U55 functional materials examination machine made by Taiwan High Iron Science and Technology Stock Company.
