Carbon Fiber Reinforced Beams
The actual area of carbon fiber cloth that should be pasted: A=10 2. 4mm2 The total width of carbon fiber cloth is: B=102. 4/ 0. 167=613.2mm The width of each layer of carbon fiber cloth is: b =61 3. 2/ 3=204 . 4mm 3 layers of carbon fiber cloth with a width of 250mm and a thickness of 0.167mm are selected and pasted to meet the requirements of the equipment room.
An idle teaching building was converted into an office building. Some of the classrooms are now changed to equipment rooms according to functional needs (using a live load of 5.OkN/m2. Original concrete beams: b *h=250mmX550mm, C25 concrete, HPB335 steel bars, and tensile steel bars of 3@25). The shear capacity of the beam meets the requirements, and the original flexural bearing capacity is 20 4. 3kN •m . The flexural bearing capacity of the beam after reinforcement is required to be 260 kN •m.
