Purpose. The authors aim to determine the features of the operation of a steel-reinforced concrete span structure with beams reinforced with an I-beam, with their pre-stressing using the bending of a steel I-beam. Methodology. To manufacture a steel-reinforced concrete span structure, it was proposed to reinforce an I-beam with a camber, which is then leveled with the help of applied external loads. For practical convenience, the vertical external forces are replaced by horizontal forces that keep the metal I-beam in a deformed state and in this state it is concreted. After the concrete streng

When constructing tunnels in mountainous areas, the drilling and blasting method is the most commonly used because of its economy.

Therefore, when using the drilling and blasting method for ordinary reinforced concrete double-line tunnels, vibration phenomena will occur and cause cracks in the first-line tunnels, which will have adverse effects on the durability and safety of the tunnel. As a response, scholars have proposed the use of steel fiber-reinforced concrete as tunnel lining. In this paper,

Steel-reinforced concrete structures at the present stage of development of the construction industry are widely used in industrial buildings with heavy loads on floors, civil high-rise buildings and various engineering structures. The article presents the results of using a nonlinear calculation method to calculate the parameters of the stress-strain state (normal stresses and relative deformations at any stage of work under load, strength and deformability) of bent steel-reinforced concrete elements, provided that rigid steel profiles and reinforced concrete work together.

Abstract:
Corrosion in steel can be detrimental in any steel rebar reinforced concrete as well as in the case of steel fibre reinforced concrete. The process of corrosion occurring in steel fibre incorporated concrete subjected to corrosive environment was systematically evaluated in this study. Concrete specimens were prepared with steel fibre inclusions at 1.5%Vf(volume fraction) of concrete and were added in slag based concrete (containing manufactured sand) and replaced with cement at 20%, 40%, and 60% of total binder. Accelerated corrosion studies were carried out using alternate wetting and drying

Abstract: Steel Fibre Reinforced Concrete (SFRC) has emerged as a promising composite material that significantly enhances the mechanical properties of conventional concrete. By integrating discrete steel fibres within the cementitious matrix, SFRC exhibits improved tensile strength, toughness, and crack resistance, addressing many of the inherent weaknesses found in plain concrete. This paper investigates the influence of fibre content, aspect ratio, and distribution on the structural behavior of SFRC under various loading conditions.
