WebChapter 4 sets out the load combinations for both simple and moment resisting frames. Information is given on the sway sensitivity of frames, frame imperfections and the use of the equivalent horizontal force (EHF) (a general approach that replaces imperfections with a system of notional horizontal forces). WebFeb 16, 2015 · Or does robot automatically caluclate some form of notional horizontal force even under pure gravity loading. Any help much appreciated. Darren. Solved: Hi, I've got an eight storey structure and under just self-weight, when I look at 'Exact deformation for bars' I notice a great deal of sway. WebIn BRE Digest 437, it is stated that lateral stability checks should be carried out based on a notional horizontal force (NHF) of 2% of the sum of the dead and vertical imposed loads assumed to act at decking level. For structures designed to BS 5950-1, the Digest states that the NHF should be increased by the relevant partial load factors. green badminton racket
