It was great help for me, they are for ETAB 9.2.0. Hope they help you. RE: Lateral Analysis In ETABS - fiaz - 11-11-2009 Dear Yasir, Please upload, PowerPoint slides for above as same is not valid.secondly, In Etabs, I have concluded from tutorial that, before assigning a wind load, we required to create dummy area objects at windward and leeward side which have no stiffness. But in CSI’s introductory tutorials, they have also created developed elevation definition at only leeward side. Why they did not create developed elevation definition at windward side. Please explain. Thanks Regards, Fiaz RE: Lateral Analysis In ETABS - Yasir - 11-11-2009 dear fiaz its not by me its from promo8 RE: Lateral Analysis In ETABS - fiaz - 11-11-2009 OK.Thanks Yasir. Regards, Fiaz RE: Lateral Analysis In ETABS - Red Alert - 11-11-2009 Dear Yassir : Lateral Story drift is against seismic Lateral displacment wind load Lateral story drift (UBC) =0.7*R*Ds<0.02 ,( if the model scaled ) where the Ds valus from Etabs output. -if the model not scaled so you should take it =0.7*R(Ds/H)<0.02, where H=story height. -lateral Displacement <H/500 , where H is the height of the building , and the wind speed is 100mph according to ASCE Also dont forget to use the values of cracked section in order to have right checks vertical elememnt =0.7Ig Beams =0.35Ig Slabs=0.25Ig RE: Lateral Analysis In ETABS - gini7998 - 11-18-2009 Hi, I think If columns have relases on each flor under the beam, then all lateral forses will be taken from the shear walls.
