Shear Stress Diagram
Cross section of beam

7.3.3 Shear Stress for ‘I’ section of beam

Example 6

A simply supported beam of 5 m span is having 200 mm
symmetrical I section with flange 200 x 25 mm

and web of 150 x 25 mm if it carries uniformly
25 mm
distributed loads of 5 kN/m. Calculate

i. shear stress at connection of flange and web

ii. maximum shear stress. 150 mm
25 mm

iii. draw shear stress distribution diagram
