I have a basic question.
My understanding is that one of the ways that simple shear connections accommodate rotations is through localize yielding, for example at bolt holes.
My understanding is also that cyclic loading that is sufficient in magnitude to cause yielding will cause crack growth...
I am trying to figure out how to design a beam to absorb the impact from a falling object. A conveyor carries 13,000 lb. parts over an industrial enclosure that we are building. The customer wants the roof beams to protect the people inside if a part falls from the conveyor. The fall distance is...
I need help finding published examples of fatigue checks for built up members.
We have an HSS16x8x3/8" serving as a crane runway. Using HSS in this application was a terrible idea ... no need to tell me that. The cranes run on polyurethane coated wheels which are not as wide as the flat surface...
I am trying to understand when 3rd party inspections are required by IBC. 1705.2.1 says that "special inspections ... shall be in accordance with the quality assurance inspection requirements of AISC 360." AISC 360 defines quality control being provided by the fabricator and erector, while...
I have a welded knee brace. The knee brace and a beam above it make up a bracket that supports the runway for an automated crane system in an industrial plating machine.
The axial force through the knee brace resolves into compression and shear at the face of the column. Loading on the weld...
The AISC code is pretty clear about what factors of safety are included for strength checks. Does anyone know if the fatigue threshold stress range in Appendix 3 includes any safety factor? If not, how much safety factor is appropriate if your objective is unlimited fatigue life?
I am working...
I'm working on a structure to support a programmed hoist system. This is a light industrial structure in a seismic design category B location. The framing utilizes tension-only braced frames in one direction, moment frames in the other direction, and all column bases are assumed pinned for...
Folks,
I'm a long time reader, first time poster looking for help with torsion. I have a HSS girder that connects 2 HSS columns in an industrial structure. The columns continue up past the girder. The girder supports WF beams on 1 side of it. There is grating clipped to the WF beams (no deck or...
