Concrete Floor Steel External Reinforcing Plate

With reference to the code for design of strengthening concrete structure the bearing capacity formula of the rc frame beams strengthened by using the exterior wrapping u shaped steel plate is briefly derived.

Concrete floor steel external reinforcing plate.

The perfect bond between surface steel plate and concrete is assumed. Strengthening concrete beams for shear forces by means of attaching steel plates to the external surfaces could provide a practical solution to the program of upgrading concrete bridges for carrying heavier loads. By the method of sticking steel plate for reinforced concrete columns. Based on practical frame structures constructional methods of the reinforced concrete rc frame beam strengthened by using an exterior wrapping u shaped steel plate are introduced.

Concrete and surface steel plates that compose the sc panel are found to be elastic. The third beam is reinforced with external sticky steel plate and the second storey column knocks off the surface plastering and after the steel jacketing reinforcement it is repainted. External steel plate systems for reinforced concrete column beam. The local stress at the tire contact area is too high and we need to add steel plate on the floor to distribute the loads.

Heavy wheel loads on concrete slab on grade when moving equipment into position during the construction phase. The stiffness of the sc panel in this part is given from the sum of the stiffness of concrete and surface steel plate. The third floor slab which is too serious decides to be demolished and re cast concrete plate.
