The flexural strengthening of reinforced concrete (RC) beams by bonding external composite materials has proved to be an effective and convenient technique. Several works, focus on mechanical behaviour continuous beam with two spans strengthened materials, were reported in literature. This paper presents the capacity RC three or repaired carbon glass fibre polymer (CFRP GFRP) sheets. Experiment...

This paper presents the flexural capacity of reinforced concrete beams designed with high-strength steel bars. Reinforced bars fy = 550 MPa are to have flexuralstrength like bar 420 MPa. According ACI 318M-19, (fy =550 MPa) allowed use as reinforcing steel, which previously unpermitted. study was conductedto represent possibility using reinforcement. There five sample thatdesign various diamete...

A large wall with vertical cracks at mid-span, varying in width of up to 3 mm wide, had been declared capable of resisting a postulated seismic load. It was not straightforward to subsequently confirm, analytically, what influence the crack had on the wall’s capacity for lateral loading. It was assumed that it was likely that the horizontal reinforcement had yielded across the crack and thus th...

During flight, many insect wings undergo dramatic deformations that are controlled largely by the architecture of the wing. The pattern of supporting veins in wings varies widely among insect orders and families, but the functional significance of phylogenetic trends in wing venation remains unknown, and measurements of the mechanical properties of wings are rare. In this study, we address the ...
