I am a structural engineer designing a government project that requires roof mounted fall protection. The type of anchor being considered is shown in the following link. It mounts with set screws to the seams of a standing seam metal roof...
I am designing a residential structure in SDC D. It is 2 stories. The 1st story is an open carport. 2 story steel HSS columns are used from the foundations to the roof. Wood shear walls are used at the 2nd story. There are NO moment connections at the 2nd story or roof. The base of the...
Does anyone have experience in using a non-load-bearing steel stud wall with strap bracing as a lateral force resisting system?
This system that we are considering is for a two-story building. The perimeter steel studs bypass the second floor. A non-moment-resisting steel frame is used to...
Section 8.11.4 of ACI 318-99 says, "joist construction not meeting the limitations of [monolithic construction and certain rib width, depth, & spacing limitations] shall be designed as slabs and beams. What exactly are the differences between the design of slabs & beams vs. joists? I see in...
I understand that when importing a picture you have to actually type in the filename (rather than browsing for it.) The filename then appears below the picture. How can you hide this filename so that it does not show up on printouts?
I am planning on learning blast design during the next few months and will hopefully attend a one week seminar on TM 5-1300 next month. My question, addressed to the blast design engineers who visit this site (if there are any), is considering that TM 5-1300 was last updated in 1990, what is...

My company will pay for membership in two professional organizations (such as ACI, AISC, ASCE, etc...)and I am trying to decide which ones to join. Which ones seem to be the most beneficial?
I'm most interested in helpful publications regarding building design.
For moment resisting roof beams in a gable frame with a column at the ridge, what is the maximum roof slope that the engineers in this forum would be comfortable with? 2 on 12? 3 on 12? 4 on 12?
This building is also in a moderate seismic zone (seismic category D, FEMA 302) and bolted flange...
I was planning on using steel moment frames in both directions for a one story portion of a building which is in a Seismic Design Category D (FEMA 302). For seismic design, it's important to have a strong column with a weak beam so that the plastic hinge will form in the beam rather than in the...
