Test Research on Strengthening In-Service Damaged Truss with Prestressed Cable

Abstract:

Prestressed cable is an effective way of strengthening. Through the model loading test on the two groups of wood truss, explore the effect of reinforcement to the damaged truss with the prestressed cable. Data show that, in the damage conditions, the bearing capacity of wood truss increased by 112%. Loading test on a group of steel truss, the bearing capacity of steel truss improve only about 12%. The reinforcement effect are different under the same conditions due to the two kinds of material modulus, stiffness parameters are different.
