WebFor example, we can create load combinations as follows. Ultimate load combination 1.4 Dead Load + 1.6 Live Load Service Load Combination 1.0 Dead Load + 1.0 Live Load When earth pressure and dead load is considered, we create following load combination 1.4 Dead Load + 1.2 Earth Pressure WebNotional loads (NL) are automatically derived from the factored loadcases within the current combination. They are applied in the analysis as a horizontal force at each beam column …

WebSome examples of where a primary load case would be used are: All dead load on a structure. The reducible live load on an office building. The easterly wind load. ... Notional Loads. A number of design codes require that a notional load be considered. Typically, this is defined lateral load equal to a percentage of the gravity loads. Webthe magnitude of the notional load on each floor is 0.002 times the vertical load applied on that floor. If the ratio of second-order drift to first-order drift (a ratio reasonably approxi-mated by the B 2 multiplier) is greater than 1.5, notional loads must be included in all load combinations. If the ratio is less than 1.5, notional
