HI how the cold formed steel design is different from the Hot rolled steel design? is design of cold formed steel structure on SAP2000 ok or some other software should be used? any other good software for CFS design? how do we apply temperature on the CFS structure.i have CFS model is sap2000...

Hi, I have a building foundation at three levels z=3,z=-18 and z=-26.5, how do i export these base reactions as .f2k format for the foundation analysis in safe.i tried exporting them, when i put elevation level -26.5 sap gives reactions at -18 but i couldn't able to get the reactions at z=-26.5...

thanx @minochord how to apply these forces in SAP2000.

after analysis go to Display>Show forces/stresses>frames the pop down appears select the load combination, and direction in which you require displacement and select show values at the end, scrolling pointer will show you the displacements.

thanx @darthsoilsguy2 and @CELinOttawa ,thanx, no apologies sir in our area most of housing societies has the practice of concrete OHWT so that its concrete. i will consider the option of steel tank on RC columns.

AWWA D100 is for steel tanks

Thanx All of you for responding @JAE: i have seniors with me at my company. here i posted it to have second opinion, to have latest issues/research/problems that might encounter on the way.Also opening this question may benefit other freshers. in my company practice is to use SAP2000 , any...

Hi I have to design a OHWT of capacity 60,000 gal (imperial). shape is octagonal on six RC columns height of the base of tank is 60',dia at 60 Elev. 23',dia at 60+5 Elev. is 37' and with this dia it goes straight up for 9',top is coned with an height of 9'. soil BC is 2tsf.how to start the...

Hi, how to make a column have fixed support, is longitudinal bars bending pattern at foundation level effect the fixity condition, mean if bars are bent inside and if bars are bent outside or bars are not bent at all they are erected without bending what will be the difference in behavior.

@avscorreia: I have two versions of SAP2000 v14.2.4 Advanced and v15.0.0 Ultimate ,the above mention "Load transfer Options" couldn't be found in these two versions.

@BAretired: thank you for your response id try as L beam

@KootK: wall is there around the periphery in between columns but it is just at lower ground(basement) in upper two stories there is no wall between columns. this wall is not shear wall but basement wall which will retain the soil just.

kindly check the link below to check columns sections http://wiki-edupunk.blogspot.com/2014/08/beams-columns-plans-and-column-sections.html

sure, here it goes, i had problem uploading to a free space. http://wiki-edupunk.blogspot.com/2014/08/blog-post_31.html

thanx KootK actually they have also cast a reinforced basement wall all around the columns periphery when design was revised it was failing in beam capacity ratio I suggested increasing column sizes but contractor have to do lot of chipping and drilling, and anchoring chemical so the need more...
