The Engineering Method: The strategy for causing
the best change in a poorly understood situationwithin the available resources.(i.e., if you understand the situation, you're doingtechnician work, not engineering.)

Engineering is it Science (knowledge)? Skill (art)?
Which is more important:
Defining the Problem? Solving the Problem?
For spandrel beams carrying cladding, limitLL deflection to max.
slab constant thickness vs. variablethickness camber : AISC tolerances are all + (no minus)
AISC Journal 1989 article by Ricker
Modern Steel Construction July 2006 article by Downey
difference between fabrication shop camber and OWJ camber
Flatness vs. Levelness

1603.1.5: include irregularities indesign data shown on drawings
1908.1.9: AF&PA wood dowel designvalues are appropriate at sill plates(compliance with Appendix D notrequired)
Gusset plates were undersized actual load (construction stockpiles of paving
materials and trucks) matched calculatedultimate capacity of the failed gussets
actual load (static) was significantly less than therated capacity of the bridge
Proof load test (moving) performed at ratedload less than 5 years earlier only primarymembers were monitored Bridge design approach: connections are
always stronger than the members no need to monitor connections
