Detailing for Weldability
Overdetailing of weld sizes and joint configurations can cause unnecessary fabrication and in-service problems and higher costs. Some designers believe
Detailing for Earthquakes
Bridges must be designed so that catastrophic collapse cannot occur from seismic forces. Damage to a structure, even to the
Detailing for Buckling
Prevention of buckling is important in bridge design, because of the potential for collapse. Three forms of buckling must be considered
Design Parameters for Tension Members
To prevent undue vibration of tension members, AISC specifications for ASD and LRFD suggest that the slenderness ratio L/ r be
Design Parameters for Rolled Beams and Plate Girders
