Section a :-Environmental Engineering 6th Sem Civil/5197/May 2019 Paper

According to IS 800:1984, Maximum Permissible tensile stress in Steel Sections is 0.6× fy.

In IS 800: 1984, Symbol fy represents minimum yield stress in Steel.

For 28mm diameter rivet, the diameter of rivet hole will be 28+2=30mm.

 

Sectional area of “ISLC 150 @ 141.3 N/m” is 1836 mm².

For 75° Fusion Angle the Effective throat thickness of 6mm welds is 2 mm.

Maximum pitch in rivets shall not exceed 30t or 300mm.

Increase in carbon content in steel cause  decrease ductility.

ΣV = 0, ΣH = 0 and ΣM = 0 are called equations of equilibrium.

In plate girder Bearing stiffeners are provided at the support.

Zero bending stress occurs at neutral axis of Beam.

b) State True or False.
