For the load combination of 0.9D + or - 1W, why do we take the negative as the critical value for design , even though there are higher positive values?<br />
<br />
For example in etabs, for combination 3 the Pu= 6000 and in the upper combination Pu= 3000 but ETABS chose the 0.9D - 1W as the design combination.Structural Eng.http://civilengineeringbible.com/QA/?qa=261/combination-negative-critical-design-though-higher-positiveTue, 22 May 2018 01:27:54 +0000how i can i learn steel structure manual design .need some book reference
