GAS TUNGSTEN ARC WELDING (GTAW) is the quality weld process. It is preferred welding process for stainless steel, low alloy steel, nickel, cobalt, titanium, aluminum, copper, and magnesium. The present work aims to evaluate the effect of Gas Tungsten Arc Welding process parameters on the quality of the weld bead. The process parameters Welding Current, Wire Diameter, Wire Feed Speed, Ratio of w...

The chloride threshold value (Cth), or critical chloride content, is defined as the chloride concentration at the depth of the reinforcement, which initiates the depassivation of steel in concrete. However, very limited information is available regarding the chloride distributions at the interface with the steel. The main objective of this work is to improve the knowledge and understanding abou...

This paper presents an efficient numerical procedure for the rapid design of arbitrary-shaped composite steelconcrete cross-sections that are subjected to biaxial bending and axial force. The design procedure allows cross-sections to be designed by solving directly for the reinforcement required to provide a cross-section with adequate strength. The new numerical procedure developed in this pap...

Rowena Harris’ recent work presents carefully composed constellations of materials and almost-repeated images. These constellations inhabit both physical, tangible space (in the form of sculptural elements and digital prints) and digital realms in the form of a video reel and an e-book. Welded steel lines extend from the gallery floor and walls, providing a formal and physical support structure...

This study developed a macro-sized polyamide (PA) fiber for concrete reinforcement and investigated the influence of the PA fiber on flexural responses in accordance with ASTM standards. PA fibers are advantageous compared to steel fibers that are corrosive and gravitated. The macro-sized PA fiber significantly improved concrete ductility and toughness. Unlike steel fibers, the PA fibers produc...

The microstructural analysis of some reinforcement steel rods used for concrete and their effect on the mechanical properties, carbon equivalent values have been studied. work subjected samples to test specimen preparation as required by standard specification each test. Samples from five different mini mills were investigated hardness, impact strength, composition, microstructure. result obtai...

Abstract:   The use of Concrete beams reinforced with a combination of fiber reinforced polymer (FRP) and steel bars has increased dramatically in recent years, due to improvement in strength and flexural ductility simultaneously. In this paper, we proposed a new equation for estimating the effective moment of inertia of hybrid FRP-steel reinforced concrete (RC) beams on the basis of the...
