Civil Engineer Bridge Design

  1. Design the interior girder for the simple span composite steel girder

Live load requirements:


Deck width =45.375 ft

Roadway width = 42.5ft

Bridge length =50 ft

Skew angle = 0

Structural steel yield strength Fy=60 ksi

Structural steel tensile strength Fu = 65 ksi

Concrete 28-day compressive strength f’c = 4 ksi

Reinforcement strength Fy= 60 ksi

Steel density Ws= 0.49 kcf

Concrete density Wc = 0.15 kcf

Parapet weight (each) Wpar =0.53 k/ft

Future wearing surface Wf = 0.14 kcf
