ENCE 455 Design of Steel Structures

VIII. Simple Shear Connection

C. C. Fu, Ph.D., P.E.

Civil and Environmental Engineering Department

University of Maryland

review bolts and welds
Review Bolts and Welds

Design bolt bearing strength (Le ≥ 1.5d, s ≥ 3d)

Design bolt shear strength – no threads in shear planes

Design bolt shear strength – threads in shear planes

Design bolt tensile strength

Design strength of the weld

  • Rn = 0.707wL(Fw)= 0.707wL(0.75[0.6FEXX])=0.32wLFEXX
