Question

What percent of factored load is notional horizontal force?

(a) 0.5%

(b) 1%

(c) 10%

(d) 20%

I had been asked this question in quiz.

I would like to ask this question from Methods and Assumptions of Analysis topic in section Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer 1

Right choice is (a) 0.5%

The explanation: Notional horizontal force = 0.5% of factored dead load + vertical imposed load at that level. Notional horizontal force are applied to analyse a frame subjected to gravity loads, considering sway stability of frame.
