Thanks so much. I am waiting your commments at weekend. As you say because of walls, reinforced walls join to the modes at last modes like 38-39th modes.
I am sharing etabs model at attached file. As you can see from model, i am analyzing a structure consist of panels up to 8 m level and steel columns from 8 meter to 13 meter. When you look modal participating ratios you can see that at first modes all x and y direction is zero. And at x side, it...
hi everyone
i am trying to model a column, i shared the Picture at the attachment. does anyone has an idea how to model this column at sap2000? i have to columns upn300 and they are connected with plates (150x10 mm) from 2 sides. and at the up of it the column (upn240) distance decreasing...
i shared the model. Can anyone look my model if something wrong in it? I have some questions about my model
i am using turkish earthquake codes. after looking periods y direction period is greater then x direction. is there something wrong at it?
also can you look the releases at the members...
i have a question. i want to use a 5/6 mm checkered plate under 238 kg/m2 dead load + self weight of checkered plate and 200 kg/m2 live load. it is at pinned from 4 edges long span is 1800 mm short span is 1000 mm. yield stress is 2400 kg/cm2. can i use it under this loads? i didnt find any...
I am modelling a steel structure roof and defining purlins with M22&M33 release. After analysis ETABS analyse this purlins not as a composite beam. How can fix it? And do a steel design except composite design?
But when i modeled the roof with composite beam with concrete after composite beam analysis; at composite beam design menu i am looking to the reports and it says my cover N/A, dont see my metal deck options there. I think because of the roof's %2 slope program dont realize it as a composite...
hi. i am designing two floor steel factory. At mezanine floor using composite beam with 8 cm concrete. And planing to put energy panels at roof. i have several questions.
1. Roof has a %2 slope. starts with 7.5 meters and finishes at 8.00 meter. How can we use rigid diaphragm? ETABS warning is...
