Notional horizontal force

WebMar 1, 2024 · The most common approaches to consider the effects of initial geometric imperfections in advanced analysis are the modelling of imperfections by directly offsetting the coordinates of the nodes, the reduction of member stiffness, the adoption of notional horizontal forces and the superposition of scaled elastic buckling modes [6]. While the ... WebThe absolute loading at the top two tiers is based on varying tier heights that affect the horizontal force components for each brace. At the remaining levels, the identical BRBF braces and orientations would not result in load imbalances and instead are designed for notional “NOT” loads.
