Innovative use of steel plates to strengthen flange

This study suggests using steel plates to strengthen large and small circular, rectangular and square reinforced concrete (RC) T-beam flange openings. Steel plates have been used to compensate for the flange concrete that is removed due to the construction of the openings. The used steel plates were mainly under compressive stresses; therefore Strengthening Structures Using Unstressed and is a much quicker operation than steel plate bonding and results in cost savings in plant and time. As a result, the industry is increasingly turning to CFRP plates to strengthen conventional structures in flexure, to cure deflection problems in buildings and to strengthen masonry walls Base plate in bending and anchor bolts in tensionend plate connections. Thick base plates are designed to transfer compression forces into the concrete block and are stiffened by the column and the additional stiffeners when necessary. The anchor bolts are longer compared to the bolts used in end plates due to presence of washer plates and grout, thick base plate and the part embedded in the Design of Simply-Supported Composite Beams for Optional flange plate (a) (b) (c) (d) (e) (f) (g) (h) Note:Optional flange plates similar to that shown in (a) can also be used with (b), (e) and (f). Figure 1.2 Alternative Steel Beam Types Concrete Slab The concrete slab forms the top flange of the composite beam. It must be reinforced with deformed bars or mesh to strengthen it against Study on an Innovative Flange Bolted-Welded ConnectionThe failure mode is due to the slippage of flange bolts as well as the gap development between the two flange plates. The experimental studies enabled improvement of the design of the connection to be used in moment-resisting steel frame structures.
