I have to design connection for sections in steel structure.
And as per our client and applicable codes requirement I have to ensure that while designing connections , apart from maximum end forces coming on members, the connection should also be designed for some minimum percentage of its max. load carrying capacity (i,e axial ,shear and bending). say for example max. axial froce Fx coming on a bracing is 100 KN , but max. axial load (compression) carrying capacity of that bracing for that particular member length is 500 KN and code says connection should be designed for min. 50% of its max. capacity. than i have to design it for 250 KN.
I can find out the max. force coming on a member , but how i can find out the maximum capacity of that type of section in a particular STAAD model , because max. load carrying capacity such as compression and bending varies based on its length for a single section type in a particular model.
So please suggest -
how to find maximum axial , shear and bending moment carrying capacity of a particular section type used in a STAAD model , based on various lengths of members used in a particular model. as axial (compression) and bending moment carrying capacity will vary in a single model based on its length.
Thanks in advance.
First, you should perform a analysis to your model.
Second, click the postprocessing and select Property in Results Setup.
Last, you can get the maximum axial , shear and bending moment carrying capacity of a particular section type in your model.
thanks xingmin.li for quick reply but the procedure u suggested is for finding out the maximum end forces coming on the member due to applied loads , and not the maximum load carrying capacity of that section type in that model , which could be higher than that mentioned in table. what i want is max. load carrying capacity not the max force.
