The Load Path Is the Story
If an engineer cannot explain how load moves from roof to slab, beam, column, foundation and ground, the structure is not yet fully understood. Structural design becomes clearer when every force has a credible route.
Scenario: A Slab Is Cracking More Than Expected
Check crack pattern, reinforcement, restraint, shrinkage, loading, deflection and support movement before assuming loss of strength. A crack is evidence; its meaning depends on mechanism and context.
