Analytical Solutions for the Flexural Behavior of Metal Beams Strengthened with Prestressed Unbonded CFRP Plates
Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...
متن کاملNon - linear analysis of externally prestressed concrete beams
In an external prestressing system, there is no strain compatibility between the cable and the concrete at every cross-section, the increment of cable strain must be evaluated by taking into account the whole structure, rather than performing the calculation at each section, independently. In this study, a method for the calculation of cable strain, which is based on the deformation compatibili...
متن کاملSize Effect of Shear Failure in Prestressed Concrete Beams
It is shown that the size effect predicted by dimensional analysis of fracture mechanics of failures due to progressive distributed microcracking agrees with the test data existing in the literature better than the presently used strength (ultimate load) criterion, which exhibits no size effect, and better than the linear i!lastic fracture mechanics criterion, which exhibits much too strong a s...
متن کاملFlexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections
The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...
