Introduction: Ferrocement is a low-cost material that can be utilized as replacement for expensive fiber-reinforced polymer (FRP), which generally used retrofitting structural and non-structural reinforced concrete members. The objective of this paper to investigate the effectiveness wire mesh in flexural members such beams. It also investigated capacity beams, are with partial or complete regu...

composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. in this paper, after modeling couple beams with and without steel plates with f.e methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

The feasibility of predicting the fracture behavior of surface cracks from shallow cracked bend specimens was investigated. The material studied was a high-strength steel stress relief embrittled to various levels of Charpy-V notch impact toughness. Material toughness was quantified in terms of the J-intergral at total specimen failure (-/„,,), using both deeply notched and shallow-notched bend...

This study was conducted to examine the structural behavior of concrete beams reinforced with local steel bars available in Ghana. The prepared from conventional materials ordinary Portland-limestone cement, pit sand and granitic stones. Steel sizes 12mm, 10mm, 8mm different millers used reinforce were tested stress-strain relationship bars. main reinforcing comprised 12mm high tensile mild pro...

One of the key damage observations in modern reinforced concrete (RC) frame buildings, damaged following 2010/2011 Canterbury and 2016 Kaikoura earthquakes, was localised cracking at beam-column interface capacity-designed beams. The beams due to curtailed longitudinal bars interface. Following these observations, without experimental data justify desirable seismic performance, controlled by we...

Abstract. Prandtl’s membrane analogy for cylindrical bars under torsion is extended to beams with multi-material cross section of any geometry. It was demonstrated that the problem governed by equations formally analogue those describing deformation an inflated membrane, differently tensioned in regions corresponding cross-section domains hosting different materials. The allows evaluate not onl...

Reinforced Steel bars used in concrete constructions are particularly susceptible to corrosion since they don't have enough resistance, which decreases durability and long-term performance. The main cause of steel bar is moisture interaction, results rust, causes cracks spalling, affects FRP bars, several benefits over such as strong resistance corrosion, higher tensile strength than a 1/4th th...

Abstract The numerical study of the hybrid reinforced concrete beam using GFRP bars has been explored in this research. Finite element software ABAQUS had used for investigation. In present research, use as a replacement to steel reinforcing longitudinal reinforcement is attempted. Further, RC by and rebars transverse compared with conventional beam. beams are tested three-point bending simulat...

The Dirc, a novel type of Cherenkov ring imaging device, is the primary hadronic particle identification system for the BABAR detector at the asymmetric B-factory Pep-II at SLAC. It is based on total internal reflection and uses long, rectangular bars made from synthetic fused silica as Cherenkov radiators and light guides. BABAR began taking data with colliding beams in late spring 1999. This ...

Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...
