The need for repair and strengthening of deteriorated, damaged and substandard infrastructures has become an important challenge worldwide. The demand for increasingly heavier truck loads is forcing bridge owners to upgrade existing structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted to investigate the feasibility of using di...

The Adomian Decomposition Method (ADM) is employed in this paper to investigate the free vibrations of the uniform cracked Euler-Bernoulli beams. The proposed ADM method can be used to analyze the vibration of beams consisting of an arbitrary number of cracks through a recursive way. Based on the ADM and employing some simple mathematical operations, the natural frequencies and the correspondin...

This paper aims to numerically investigate the structural behavior of reinforced high-strength concrete (HSC) beams retrofitted by Carbon Fiber Reinforced Polymer (CFRP) sheets after cracking. Six pre-cracked HSC with CFRP having identical reinforcement are tested four-point loading until failure using Abaqus software, besides two others without as control beams. attached on three beam sides in...

The purpose of this research was to investigate the creep behaviour of the heterogeneous Timber-UHPFRC beams. New developments have been done to further improve the structural performance, such as strengthening of the timber (glulam) beam by bonding composite material combine with an ultra-high performance fibre reinforced concrete (UHPFRC) internally reinforced with or without carbon fibre rei...

Fiber Reinforced Polymer (FRP) bars are anisotropic in nature and have high tensile strength the fiber direction. The use of High-Strength Concrete (HSC) allows for better high-strength properties FRP bars. mechanical can yield to large crack widths deflections. As a result, design concrete elements reinforced with materials is often governed by Serviceability Limit States (SLS). This study inv...
