Lets say you have two intersecting beams bolted flange to flange, where the upper beam is supporting the lower beam. You check prying for both beams, and both have resulting prying forces due to their thin flanges... Would the prying forces for both beams be additive to bolt tension? Or would...
My employer wants to support a catwalk end with a caged ladder.
On past projects requiring ladders for maintenance access, I have always independently supported catwalks/platforms and attached the ladder to the catwalk such that the ladder itself is not supporting the catwalk or platform.

Application: Fully Pre-tensioned Bolts subject to tensile cyclical loads. I am looking specifically at AISC 360-10 today since that is the edition I have at the office (I have 360-15 at home), although I think 360-15 is similar.
Appendix 3, section 3.4, states "For joints in which the...
I'm looking for opinions on whether or not bolted tension members that see cyclic load can use snug tight bolts (bearing type connection). In this case, lets consider an angle tension hanger with a bolted connection (bolts in shear) that supports a piece of equipment that sees some cyclic load...
I have a situation where I am being asked to remove (or relocate) several column posts from a mezzanine in an industrial plant setting. The mezzanine is made up of posts from the floor at about 25 foot spacing in both directions. The Building Columns are at 50 foot spacing in both directions...
Does anyone have any experience calculating prying action on beam clamps, such as the below example? In this case assume the flange of the WT below is stiff enough to prevent prying. Could you provide some guidance on how to determine prying force to add to initial bolt tension? I'm assuming...
Would you consider the channel at midspan of the attached angle beam to laterally brace the angle?
My initial thought was "No", because the vertical leg of the angle is in compression and the channel is welded to the horizontal tension leg of the angle. On the other hand, I do think channel...
IN THE ATTACHED DIAGRAM, ASSUMING THE PLATES ARE CONTINUOUS IN AND OUT OF THE PAGE, WILL THE PLATES BEHAVE LIKE A COMBINED SECTION?

Is anyone else experiencing much longer model run times with the latest update of RISA 3D?
I just updated from 16.03 to 16.04
I had a model that ran fine using 16.03 in less than a minute. Now with 16.04 the exact same model gets stuck in a seemingly endless loop of solving for P-Delta...
My situation is an S6x12.5 monorail that spans too far without some sort of reinforcing (24'-5") simple span without any lateral bracing between supports. My supervisor (not a licensed engineer) wants me to weld a W8x18 or similar larger beam to the top of the S6x12.5.
My question is how...
