You will learn step by step how to calculate the main variables to ensure the safety and efficiency of your structure, covering topics such as distributed load, bending moment, allowable stress, and much more. If you work with structural projects or are studying steel structures, this video will help you better understand the behavior and application of W/I steel profiles in your projects. Watch until the end to get valuable tips and information that can optimize your work!

SLAB LOAD: Assuming a slab of 4.00m x 5.00m and 0.15m high. Self-weight: 4.00m x 5.00m x 0.15m x 25kN/m³ = 75kN Subfloor: 4.00m x 5.00m x 0.05m x 21kN/m³ = 21kN Flooring: 4.00m x 5.00m x 0.02m x 20kN/m² = 8kN Variable load: 4.00m x 5.00m x 1.50kN/m² = 30kN Total load (Q) = 134kN Distributed load (q) = 134kN ÷ (4.00m x 5.00m) = 6.70kN/m² q1 = q x (l ÷ 4) x (2 – l ÷ L) q1 = 6.70 x (4.00 ÷ 4) x (2 – 4.00 ÷ 5.00) q1 = 8.04 kN/m (In the direction of the smaller span) q2 = q x (l ÷ 4) q2 = 6.70 kN/m (In the direction of the larger span) MASONRY Masonry load = wall height x weight Masonry load = 2.70 m x 1.9 kN/m² = 5.13 kN/m CONSIDERING THE SELF-WEIGHT OF THE BEAM Add 5% 8.04 kN/m + 5.13 kN/m = 13.17 kN/m 13.17 + 5% = 13.83 kN/m MAXIMUM BENDING MOMENT M = (q . l²) ÷ 8 M = (13.83 . 5²) ÷ 8 M = 43.22kN.m Md = 43.22. 1.4 = 60.51kN.m RESISTANT MODULE Wx = (K . Md) ÷ σe Wx = (1.60.510) ÷ 250 Wx = 242.04cm³ CHOSEN PROFILE Profile W 200 x 26.6
