The deflection of concrete beams reinforced with GFRP bars is higher than those which are reinforced with steel bars. The purpose of this paper is to propose a new equation for estimating the effective moment of inertia in FRP-reinforced concrete beams. This will be accomplished by using experimental results and the genetic algorithm approach. Genetic algorithm is used for optimizing the error ...

This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...

This study presents a new procedure based on Artificial Neural Network (ANN) for identification of double cracks in Functionally Graded Beams (FGBs). A cantilever beam is modeled using Finite Element Method (FEM) for analyzing a double-cracked FGB and evaluation of its first four natural frequencies for different cracks depths and locations. The obtained FEM results are verified against availab...

This study undertaken on a nine-year-old cracked concrete panel further investigates the impact of cracks corrosion performance conventional steel reinforcement in marine-exposed to explain observed monitoring data. The present data covers seven 1.80 m long (12.6 m) reinforcing bars embedded good quality (w/b = 0.40 and cover >75 mm). Each bar was crossed by two horizontal (surface crack widths...

A study of the mechanisms of cracking-induced mistuning in bladed disks is presented in this paper. An analytical model for a bladed disk was formulated using lumped-mass-beams, and a cracked blade was represented by a beam with a through-crack at the root. Local stiffness reduction due to cracking was incorporated using a flexibility matrix method. The dynamic characteristics of the bladed dis...
