Steel Beam Supporting Masonry
Steel Beam Supporting Masonry
(OP)
Hey all,
For a 13' steel beam subject to dead and snow loads, the following are the load combinations considered for strength and serviceability:
Strength:
1.2D+1.6S
Serviceability:
1S (Live Load Deflection)
1.5D (Long Term Creep Deflection)
Deflection is limited to L/600 or 0.26"
Does this seem like an appropriate approach?

I was thinking that I saw the 1.5DL for long term creep in the masonry code (ACI530-05) or on a forum here. Would that only apply to masonry lintels then. Is there a long term dead load factor greater than 1 that should be checked for a steel beam supporting masonry then? Thanks in advance!

I would use 1.0*D for creep of a steel beam because the magnitude of creep is negligible. For masonry, 1.5D or more may be warranted.
