Web9. Verify the beam for instantaneous and final deflection criteria. Deflections include: Instantaneous deflection: It can be calculated with the load from the characteristic load combinations found in Step 5. Standard beam deflection formulas for common support types and loading conditions are shown in Figure 8. WebAug 17, 2024 · The max deflection of the rafter is 36mm under live load, which passes the limit check for the rafter itself. However, if I look at the 2m long purlins of the roof that span from wall to the mid span of rafter. The deflection of the purlin will be 0 at one end (wall) and 36mm at another, which is L/55. Is this acceptable? franklin cigar and tobacco franklin la

Δ = P L3 / (48 E I) where. Δ = deflection (sag) at midspan (where concentrated load acts) P = the concentrated load. L = rafter span (length) WebBeam deflection is when a beam bends or sags under its own weight or due to applied loads. Basically, it's the amount of displacement or bending that a beam experiences when subjected to a load. Think of it like a diving board. When you stand on the end of the diving board, it bends and dips down. That's beam deflection in action! franklin church of christ texas
