SHEAR FRICTION AND FRACTURE BASED MODEL FOR REINFORCED CONCRETE BEAMS WITH RECYCLED MATERIALS

Shear resistance by beams without stirrups presents the transfer of shear and normal principal stresses across the open cracks within reinforced concrete (RC) beams.The complexity of the shear mechanism is further complicated by the distorted structure of RCA, which is composed of hardened adhered surface mortar and virgin aggregate.Compression fie

Abstract Background Resemblance to raptors such as hawks (Accipiter spp.) is considered to be an adaptive strategy of cuckoos (Cuculus spp.), which has evolved to The Fast and the Furious protect cuckoos against host attacks.However, the effectiveness of the mimicry remains controversial, and is not yet fully studied for highly aggressive hosts.Met
