Beam Specification Load Requirements Results and analysis
Length = 4.8 meter, Clear Span length is 4.5 meter. Dimension = 350 mm (Overall Depth) x 250 mm (wide), Grade of Concrete = M 30, Grade of Steel = Fe 500, Code design = IS 456
Explosive Load (Pressure) = 100 Kg, 0.065 MPa for detonated in 10 m distance act at center of Beam
Deflection = 1.468 mm, FOS = 2.5, Singly Reinforced Cross Sections. 20 mm diameter of bars used at 2-numbers in bottom sides. Figure 10 Figure 11 Doubly Reinforced Cross sections. 10 mm diameter of bars used at 10-Number in top and bottom sides. Shear Reinforcement = 8 mm diameter @ 9-numbers of links, 230 mm c/c distance.
Explosive Load (Pressure) = 150 Kg, 0.0975 MPa for detonated in 10 m distance act at center of Beam
Deflection = 2.446 mm, FOS = 2.5, Singly Reinforced Cross Sections. 20 mm diameter of bars used at 3-numbers in bottom sides. Doubly Reinforced Cross sections. 12 mm diameter of bars used at 12-Number in top and bottom sides. Shear Reinforcement = 8 mm diameter @ 9-numbers of links, 230 mm c/c distance.
Explosive load above 150 to 500 Kg, detonated with 5m distance act at center of beam Increased depth of beam 400 to 450 mm, and provided pre tention or post tensioning wire ducts. And following the special case additive material. Increased the grade of concrete.
