Introduction Wood construction is increasingly using engineered wood products.
Adhesives are the key part of these engineered wood products and play an important role in the performance of engineered wood products.
How do the bond lines of engineered wood behave under extreme cold climate?
Engineered wood in Cold Climate The main objective of this part project is to determine how engineered wood behaves when exposed to temperatures between 20 °C to -60 °C.

Research on Working Behavior of Prestressed Curved Girder Bridge Fan Wang1,2,a, Zhifeng Luo 3, b , Shenghao Mo 3, c 1Architectural Design and Research Institute of SCUT, Guangzhou, P.R.C 2State Key Laboratory of Subtropical Building Science of SCUT, Guangzhou, P.R.C 3School of Civil Engineering and Transportation of SCUT, Guangzhou, P.R.C a33204981@qq.com, b744680648@qq.com, cmoshenghao2008@126.com Keywords: Prestressed curved girder bridge, ABAQUS, Working behavior Abstract.
Prestressed curved girder bridge is a important structure type in modem traffic engineering．With the development of economical level and situation of the opening in our country, a large lumber of curved girder bridge have been taken for its favorable linearism and good adjustability in any kinds of ground．This paper illustrates the working behavior of the prestressed curved girder bridge and use ABAQUS to analysis a simple prestressed curved girder bridge.
Lack of more practical calculation program makes Curved Beam, especially, prestressed concrete curves box girder bridge which has been widely used in practical engineering, analysis and calculation becomes more difficult, and hard to accurately reflect the force characteristics.
