Regarding the web plates installed on a beam splice, does anyone know why a diamond shape would be used in lieu of a standard rectangular plate? I have seen this on older structures and some erectors have mentioned this.
I need to design a concrete foundation for a motor, belt driving a line shaft. What do I need to calculate the forces from the motor/line shaft so I can design the foundation?
What are the implications from switching from a Tube Steel member, and using steel plate to build the section as a weldment assembly (other than the lower yield stress).
I have a short 8"x12"x1/2" TS column that is 5' tall, with one beam tying into it. Originally it was designed to support rolls of material basically resting on the top, with minimal lateral forces. However, there is now a need to push the load sideways on this column,introducing a signifcant...
There is a timber floor (3" thick by 6" wide)spanning 8' between support beams. There is 1" plank flooring running transverse to the 3" timbers. How do I calculate the available floor loading, accounting for the 1" transverse plank flooring.
I have the same question for a 3"x6" timber floor...
I have designed a steel pipe to be used as a support beam to support roll goods for material handling. The pipe spans 6 feet between support brackets, and therefore is over the allowable 50 lb weight limit for one employee to lift. I would like to look at designing an aluminum pipe to replace...
I need to evaluate an older steel structure, and wanted to know if anyone knew of a good site to get the properties of steel beams as the grades have changed throughout the century.
I have a lifting beam that is detailed in the attached sketch (5/8" thick flat steel plate, 4'-1" long, 4" high, with 1 Lug Plate in the center). I to determine what the load rating would be on this. Any help with calculating this would be great.
I am looking at an existing brick masonry arch that is cracking at the center of the arch. Can anyone provide some references or help with calculations on evaluating the existing arch? If so, I can provide some detail on the arch in question.
We placed a 6 1/4" Slab on Metal Deck a couple months ago, and now there are small cracks above every support beam (which are 3'-9" on center). I have attached a drawing showing the resteel layout that was specified. Any insight to why this may be cracking would be greatly appreciated.
I have a concerete slab that has fork truck traffic on it, which has settled in one section. The settled section shows some brick and debris (fill material), however the remainder of the borings show Dry Brown Fine Sand, Little Silt down 15'. Should I be concerned with the Dry Brown Fine Sand...
Does anyone know a general rule of thumb to what the effect of heat is on A36 Structural Steel? What temperature does it start to carbonize, and what temperature does it begin to fail?
