One of the benefits of using strain gage recordings to evaluate movable bridge imbalance is that it provides a measurement of the dynamic friction of the system during bridge operations. Experience demonstrates that there are significant variations in movable bridge system friction from bridge-to-bridge and sometimes from test-to-test.
In this paper, engineers Ryan Kanagy and Ralph Giernacky present an analysis of dynamic friction from movable bridge strain gage recordings to illustrate variations in dynamic friction and to provide a comparison of the measured friction with the AASHTO prescribed calculated dynamic friction used when sizing prime movers for movable bridges.
Presented at the HEAVY MOVABLE STRUCTURES, INC. 20th Biennial Movable Bridge Symposium.
