Crane Runway Girder Design Example (ASD)
Example 14.1.1—Crane Runway Girder Design Example (ASD)
Given:
Use ASCE/SEI 7-16 to design an ASTM A992 W-shape runway girder for a CMAA Class B crane. Assume no reduction in
allowable stress due to fatigue. The design parameters are:
Type of control: cab-operated
Crane capacity = 20 tons (40 kips)
Bridge weight = 57.2 kips
Combined trolley and hoist weight = 10.6 kips
Maximum wheel load (...
