I have two steel text books and the steel manual that all refer to Rn for the base metal being FBM*ABM where ABM is the "Cross-sectional area of the base metal". Neither of the text books describe what how to calculate ABM and in the manual Table J2.5 just refers you back to J4 which is where...
I have an addition going next to an existing building. I need to put a wall with a strip footing approx. 4' below an existing spread footing. The size of the spread footing is unknown but its edge distance to the new walls strip footing edge would be anywhere from 1.5-3.5 feet. The building...
I have an 8ft square spread footing supporting approx. 20K. I need to get a wall along side it that will only be two feet away from the spread footings edge and the depth from the bottom edge of the spread footing to the bottom edge of the walls strip footing is four feet. I don't have any...
I have a 4' concrete pier that will have loads of approx. 50K vert. and 2K horizontally and is supported by a 1'-0" thick spread footing. The pier is located inside a concrete wall of equal height on a 8" strip footing. Just curious I need to isolate the footings at all or if I should plan on...
Never mind the part about all the diagonal web members being in the same direction. It is a 100' Howe truss made from two 50' sections, making it a regular good ol' Howe truss. Thanks for you quick responses.
I am modeling some existing existing truss in RISA. I have always thought that truss members should be modeled with pin connections. The existing truss is completely welded. So, should I still model this as pin connected? Also, I only have hand sketches of these trusses and in one of them...
Had an interview with a company today that is employee owned. They mentioned that they would give me projects for a while and then it would be my responsibility to go out and find my own projects. I only have a year experience and I have no idea how to go out and wrangle up engineering jobs...
I'm designing a combined footing w/ a new 1'-0" wide X 2'-0" deep cast in place footing over an existing footing. As min. (0.0018) requires (2) #5 @ 1'-0" for transverse bars. This seems like overkill and I believe the cost will get too high for doweling in (2) bars every foot. Is there...
