👉Load Distribution Two Way Slab To Beam
💫A two-way slab carries load in both directions (toward beams on all four sides) when the slab aspect ratio (longer side ÷ shorter side) is not large (rough rule: between about 0.5 and 2.0).
📌The slab load is transferred to beams as line loads (kN/m) — think of the slab as many narrow strips that hand their load down to the beams beneath them.
📌Common practical methods to determine the load carried by a particular beam:
🏷1. Tributary-area method (simple, conservative): each beam takes the load from the slab area that is closest to it.
🏷2. Equivalent strip / direct design method (used in code handbooks: ACI, BS, IS/BIS) — account for two-way action and give moment distribution coefficients.
🏷3. FE / plate analysis (most accurate) — used for complex geometry, openings, irregular supports.

This understanding to us interesting.
