Shear strengthening of RC beams with high performance jacket

摘要: The possibility of strengthening RC elements for increasing the bearing capacity under shear actions is an important issue in retrofitting field. In existing structures, made ’60s and ’70s, reinforcement often not sufficient to satisfy prescription current codes. Hence, xc0020retrofitting these structures it necessary increase capacity. A possible use low thickness high performance jackets purposes analyzed herein. are with a fiber reinforced concrete, or without additional 2mm diameter steel-wire mesh. Two different concrete investigated: self leveling rheology, that can be cast reduced thickness, thixotropic material placed molds. The were used reinforcing 3m long beams. tested up failure comparison between obtained results presented
