The environmental risks associated with construction activities are being monitored, especially given the global construction boom, in which the United Arab Emirates is a major participant. Construction activities near Gulf water cause variations in the ecosystem, yet whilst the Environmental Protection Agency (EPA) has given much attention to envi...

This work discusses the reliability of computer simulations and analysis in evaluating the structural performance of reinforced concrete beams under dynamic loads through multiple computer models. The computer simulation using Finite Element Modeling allows for predicting the behavior and failure modes of reinforced concrete beams under impact load...

This work explores the behavior of self-compacted concrete produced with fly ash as cement supplementary material and basalt fibers. A combination of desert dune sand and finely crushed aggregates were used as fine aggregates; the dune sand served as sustainable material as it is a regional material and does not need further pre-processing before u...

This article presents some of the results of an experimental study that evaluated water absorption characteristics and rate of strength development of geopolymer mortar where the binder consists of alkali-activated slag or slag with 25% fly ash replacement. Samples were cured in air at 22 ± 2 °C and 70% RH. From 1 to 7 days of curing, the increase...

Dapped-end beams (DEBs), commonly known as half joint beams, are broadly used in bridge constructions. The reduction of the depth at the supports of the beam makes it a critical shear area and vulnerable to damage. Being used primarily on bridges, dapped-end beams are susceptible to dynamic impact loading, which is more brutal than static load case...

Reinforced concrete Dapped End Beams (DEB), also known as half-joints, are used in bridges and many other pre-cast constructions to reduce end depth and increase lateral stability. Dapped end beams are expected to experience dynamic loads when used in bridges, the available past studies on the behavior and damage assessment of DEBs are mainly for s...

The behavior of a reinforced concrete dapped-end beam under dynamic load is expected to vary from its behavior under static load. Although, many studies have been conducted on the performance of reinforced concrete rectangular beams under different types of dynamic loading, but in-depth investigations on the preformation of half- joints or dapped-e...
