Developments in nanomaterial technology have generated a strong research interest the construction industry aiming at enhancing properties of concrete. Many studies explored use engineered such as nano-silica, carbon nanotubes (CNT) and nanofibers cementitious composites. Recently, focused on Graphene Oxide (GO). is single atomic layer thick two-dimensional form graphite GO oxidized graphene wh...

The sustainable development goal (SDG) 14 of the 2030 Agenda for Sustainable Development aims at protection, conservation, and management coastal ecosystems resources, including by strengthening their resilience, to avoid significant adverse impacts. Coastal/marine structures are exposed aggressive environmental conditions, such as chloride laden environment. Deterioration reinforced concrete l...

a constitutive model based on two–dimensional unstructured galerkin finite volume method (gfvm) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. the developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...

Background Longitudinal barriers are systems that consist of three basic elements: end treatments, length of need sections, and transitions. Each element needs to be designed and evaluated to assure that safety requirements are met. This applies to transitions for portable concrete barriers (PCB). The specific design features of PCBs and their associated size and mass complicate the design for ...
