Problem in Deflection Limit ( ETABS) Help! - hamzeaziz - 10-03-2010 Hi guys I have a problem with the value of Deflection limit in ETABS for Steel design. As you see below there is a picture of perfrences tab and its is value. In yellow mark all the value are as i need it for deflection limit. But as you see below after analysis and design the limit for deflection control are same for all type of loads, even its equal L / 472 ( 25.4mm) !! So where the problem is ? please someone help me! Thanks RE: Problem in Deflection Limit ( ETABS) Help! - visu - 10-03-2010 Just read the values in your input table, below your yellow cloud of first fig. This govern the design DL limit, abs = 0.0254 Super DL+LL, abs = 0.0254 ..... It is in meter. (25.4mm) You have to modify these values. Regards, Visu RE: Problem in Deflection Limit ( ETABS) Help! - hamzeaziz - 10-03-2010 thanks Another question, there is 3 types of deflection check in view/revise overwrite which are: Ratio , Absolute and Both ,So which is more important Ratio or Absolute deflection ?
