Engineering Design Coach
Select your discipline for a mock checklist of design checks, failure modes, and applicable standards.
Design checks
- • Flexural capacity φMn ≥ Mu
- • Shear capacity φVn ≥ Vu
- • Lateral-torsional buckling for unbraced length
- • Connection capacity
- • Deflection limits
Failure modes
- • Yielding
- • Lateral-torsional buckling
- • Local flange/web buckling
- • Fatigue at welded details
- • Connection block shear
Missing calculations
- • Effective section properties with measured section loss
- • Fatigue category check for welded retrofit
- • Bracing force demand
Applicable standards
- • ASCE 7
- • AISC 360
- • AASHTO LRFD
- • AWS D1.5
Load cases
- • 1.4D
- • 1.2D + 1.6L
- • 1.2D + 1.0W + 1.0L
- • Pedestrian crowd load
- • Construction staging loads
Safety checks
- • Temporary shoring during retrofit
- • Access and fall protection
- • Load posting during construction
Validation methods
- • Independent hand check
- • Alternate model (frame vs line girder)
- • Comparison to load rating
Serviceability
- • Deflection ≤ L/360
- • Vibration comfort for pedestrians
- • Crack control in deck
Constructability
- • Field welding vs bolted plates
- • Staged closure of the walkway
- • Delivery and lifting access
Sustainability
- • Retrofit versus replacement carbon comparison
- • Reuse of existing substructure
- • Coating system durability
Life-cycle
- • Recoating interval
- • Inspection frequency
- • 50-year present worth of maintenance
