The Research of Thermosetting Resin Matrix Composite Reinforcing Application in the Web of Truss Bridge
Keyword(s):
A significant number of concrete members were strengthened by carbon fiber reinforced polymer (CFRP).However there are only a few applications in strengthening steel structure with CFRP. The three-dimensional model of the long span bridge is made by using the finite element software ANSYS and do the force analysis of it ,then make composites reinforcement in order to Improve the structure strength and increase bridge life. The conclusion received of this paper is that composite patch at the end of web is more effective than in the middle of web. By picking up the stress distribution of every layer, the law of stress is obtained.
