Shear Resistance of Glulam Beams with Cracks
A reduction of the shear resistance was introduced with the crack factor kcr in Eurocode 5. The factor 0.67 corresponds to cracks that have a depth of 1/3 of the beam width, which rarely occurs under normal conditions. The glulam industry in Sweden has not observed any problems or shear failures due to cracks with previously used shear values. Hence the design requirements do not seem reasonabl...
متن کاملMoment-resisting connections in glulam beams
This paper describes an experimental investigation into the use of steel bars bonded into glulam timber beams with epoxy resins in order to provide moment-resisting joints between glulam beams and steel supports. The objective of this research was to provide information about the bending and shear strength of such connections. Past research has investigated the use of steel rods epoxy bonded in...
متن کاملBehavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets
In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...
متن کاملAnalytical 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 کاملExperimental and Analytical Study on Reinforced Concrete Beams in Bending Strengthened with FRP
The performance of the interface between fiber reinforced polymer (FRP) composites and concrete is one of the key factors affecting the behavior of strengthened reinforced concrete (RC) structures. Existing laboratory research has shown that RC beams strengthened with FRP sheets usually fail because of either debonding of the impregnated fabric from the concrete substrate or fracture of the FRP...
