Bond Behavior of Cfrp Strengthened Steel Structures
Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...
متن کاملStructural Performance of Steel Pile Caps Strengthened with Perfobond Shear Connectors under Lateral Loading
The conventional strengthening strategy on the connection between the steel pile cap and reinforced concrete footing requires a series of complicated processes such as the distribution of reinforcing bars, their anchorage into concrete, and the usage of shear keys. This study investigates the structural performance of steel pile caps strengthened with newly proposed perfobond shear connectors s...
متن کاملBehavior of steel monopoles strengthened with high-modulus CFRP materials
This paper introduces a strengthening technique for steel monopole towers using high-modulus carbon fiber reinforced polymer (CFRP) materials. The technique is based on a theoretical and analytical investigation including testing large scale steel monopole towers strengthened with different CFRP materials and connection details. Based on the research findings, design aspects and installation pr...
متن کاملAnalysis of Concrete Bridge Girders Strengthened with Cfrp Laminates under Service and Extreme Loading Conditions
Externally bonded carbon fiber reinforced polymer (CFRP) laminates are a feasible and economical alternative to traditional methods for strengthening and stiffening deficient reinforced concrete and prestressed concrete girders as shown in Fig. (1). Although extensive research has already been undertaken to investigate the behavior of CFRP strengthened bridge girders, the majority of work condu...
متن کاملEffects of Horizontal Deficiency Location on the Structural Behaviors of Steel SHS Short Columns Strengthened using CFRP
Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...
