2014年5月2日 · Hello everyone. I had a question about Table 3-10 of the AISC Steel Manual 14th edition. I wanted to know what the dashed lines being cut off beyond a certain Lb represented. For example, on 3-134, a W12x19 member does not extend beyond a Lb of ~10.25'. Does this mean if I use a W12x19 with...

2010年11月29日 · The W12x19 may also help as a torsional brace depending on the relative stiffness and conection details with respect to the main beams. I've analysed this problem using handouts and notes from a class on structural stability taught by J.A. Yura. Yura published an article on beam bracing that covered the basics but I haven't bothered to look for ...

2009年5月21日 · The existing steel is being called out with their original designations, i.e. 12B19, 14WF34, 15I42.9, etc. I think we should use the current section calls - W12x19, W14x34, S15x42.9 etc., but am in a very small minority. It was pointed out that this way they (Contractor and detailers) will know it is old steel.

Since steel is bought by the pound, you would use the lightest section possible if height is not a problem. The best choice would be the W12x19. Finally, I have a hard time believing that the roof support dead load is 5#.

2024年3月4日 · Hope you are all good. I'm working on a beam-over-column connection with a 4" wide beam (W12x19). The beam has a 2 1/4" gauge, and I'm considering using 3/4" Ø bolts. Can you advise if this bolt size is suitable for this beam considering only the edge distance which is 7/8"? As J3.4 advises min. edge distance is 1" for 3/4"Ø bolts

2005年5月18日 · Using AISC tables, I get the same result: W12x19 But using tables based upon span, I get a heavier beam. Do I need to satisfy both design methods? I have been designing according to DL+LLr and the moment at the connection to the column. Now I am being asked to meet another design standard. Does the beam have to meet both design methods, or just ...

2007年1月3日 · "Please provide the dimension off line 'x' for the W12x19..." supporting the RTU curb. Fabricators get insolent because they can't "finalize" shop drawings without these dimensions. We'll get the cut sheet from the MEP for a TRANE unit with dimensions and weights of the unit, and we provide support.

1998年12月26日 · A steel erector has asked to review a mezzanine project that involves recently installed composite beam framing where the steel anchor studs were installed along the deck's high flute. We have 3" concrete over 1 1/2"x18 ga composite deck (4 1/2" slab) with 3/4"x4" headed studs. In this situation, the deck is parallel to the supporting W12x19 beam.
