Ok, sounds good i'll take a look. Thanks [thumbsup2]

Thank you all for comments! I agree and most likely would also add roof bracing across the middle of the building, and also on short sides, if i designed it myself. As you pointed out there are several questionable solutions in design, but main focus is on middle columns. In general in situation...

Yes, forgot to mention roof has covered with bearing sheet, but it's not calculated as diaphragm.

@Canwesteng Thanks for comment. Project is already done by third party, we just have discussion in our company. Columns are precast, fixed with four anchor bolts, is it 100% rigid, i'm not sure and it's another topic. Regarding effective length, i also think that there must be 2.0 for all...

Hi all, I recently came across a question about column effective length in unbraced multi-frame system. Building has a vertical wind bracing in all four planes and triangle bracing system in roof only on two opposite sides. Section view which describes situation is something like in attached...

Thank you for response!

For model i made a beam member frame and plywood sheeting. In program there is an option to add translational release between wood stud and plywood sheet as a spring constant. But i have to calculate it somehow... see pic below. And i'm not convinced that this is the right solution...

Challenge is to understand how to add or simulate screws or nails in such a panel, as they are the most important part of panel. I have found information in internet resources how to simulate fastener behavior with springs, but it's to complicated and takes a lot of time to model and define...

Yes, i'm structural engineer and i'm working on this project to find out how to get internal forces end deformations of wood frame shear wall. That is why i want to start with simple 2D panel calculation at first and maybe more complex 3D later. But the goal is not to model perfect 3D panel with...

Hi all! Need some help in wood panel wall model design process. Does anyone tried to make something similar ? For the beginning i'm started with beam frame design and plywood cladding in 2D modeling environment to understand is it possible to design something like that at all... and right way...
