Immediate deflection formula
WitrynaThe short term live load deflection is 125 0.078 0.111 88 liveload Δ= =long term in The ACI code limiting value for the present case is found to be 1/480 times the span, or … Witryna1 lip 2024 · Euler and Bernoulli made assumptions (parallel sections remain parallel, etc), played around with variables and -- poof! -- out came the fundamental beam equation, from which we can then derive the deflections for different boundary conditions. Being theoretical equations, we can be sure that they are, by definition, unit-agnostic.
