Hello,
I am working on a multi-story, all concrete structure that I've modeled using plates in RISA 3D. I'm at the point where I need to apply my lateral loading and I'm unsure of the best approach to capture the diaphragm action of the concrete floors. Specifically for seismic, I know I can...
I have a situation where we want to reuse existing precast prestressed piles below our new structure. The thought is that we can just crunch off the concrete on the top x' of the pile, exposing the strands, and splay them out whatever their development length is in order to develop their full...
What are the current thoughts on calculations for horizontal braces that are offset some vertical distance below the main beam top of steel (say 3")?
AISC Steelwise says that the moment induced in the brace due to the eccentricity between the brace centroid and the beam centroid can usually be...
I have a concentrically braced frame, steel, stair tower, with approximate plan dimensions of 24'x9' and an approximate height of 50'. This is an industrial application, where the tower is being used to access a bridge between two tanks for general maintenance. What is an appropriate lateral...
See attached picture. Is there a minimum cover from the top of a footing or slab to the bottom transverse bars of a wall, just above the construction joint?
Thanks in advance!http://files.engineering.com/getfile.aspx?folder=ca782a31-f63c-4e8d-817f-db21d2b3bd6b&file=eng-tips.pdf
Does anyone know of any good (and free!) cast-in-place anchor calculation templates and/or programs? I'm looking for applications in both piers and in slab on grade. Hilti's PROFIS Anchor program seams to leave out some breakout checks and I'm not sure how Powers PDA program holds up.
When you are providing a moment connection for a cantilever beam that is supported by a main supporting beam, what is the reason for providing a beam with a moment connection on the other side of the main supporting beam, in the same location as the cantilever, even though the additional moment...
