Support Footprint Method Fig. 2.7 Asymmetry building in vertical and horizontal load
2.2 Estimating Overall Forces -Vertical dead loads(5~10kN/m2) -Vertical live loads equivalent dead loads(2~5kN/m2) Horizontal wind load Horizontal earthquake load
2.2 Estimating Overall Forces -Vertical dead loads(5 ～10kN/m²) -Vertical live loads = equivalent dead loads(2 ～5kN/m²) - Horizontal wind load - Horizontal earthquake load
2.2 Estimating Overall Forces Horizontal wind load depends upon Building surface area exposed to the wind Wind load intensity of the area
2.2 Estimating Overall Forces Horizontal wind load depends upon - Building surface area exposed to the wind - Wind load intensity of the area
2.2 Estimating Overall Forces Horizontal earthquake load depends upon -Distribution of mass in building -Height of the building -Earthquake intensity
2.2 Estimating Overall Forces Horizontal earthquake load depends upon -Distribution of mass in building -Height of the building -Earthquake intensity Basic definition
2.2 Estimating Overall Forces Procedure to estimate the loads: -Determine building volume or surface area -Apportion total mass or exposed surface area -Determine the EO or wind effect of each component -Sum component effects to reveal overall effect
