2006年9月28日 · Our department is engaged in a debate over use vs utilize. Our editor is arguing that "utilize" should not be our word of choice, while another employee responded: I am inclined to use the word “utilize” whenever I am referring to a tool, or for emphasis.

2016年4月18日 · I agree, for this type of structure, we would detail to AISC360 (Table 15.4-1, OCBF w/ unlimited height). But for sake of argument, say we did detail to OCBF, R = 3.25. I think the correct approach is to utilize Ch15 for the frame design, since it is responding like an OCBF system, and not a nonstructural component.

2002年10月3日 · Consider a standard hole 3/4 inch diameter A325 bolt in shear. Allowable stress for bearing type (N) connection is 9.3 Kips, and for slip critical (F) connection is 7.7 Kips Slip Critical connection are required to be inspected in the field for correct tension with torque testing...

2017年4月13日 · Hello! I have a question regarding factored vs unfactored loads. Sometimes I come across foundation plans that call out a required screw pile capacity as an unfactored load. In Canada, we can calculate a ULS snow load and SLS snow load – the only difference between the 2 being an importance...

2013年6月19日 · The structures all utilize painted galvanized plates. The history has shown that the maint. routines of repainting the plates works well and is far cheaper than special alloys. the plates are typically oversize allowing for a large amount of rust before ever compromised.

2009年4月2日 · I'm trying to find out when to use weir equation or orifice equation for an orifice in an horizontal pipe. Is this relation true? Orifice equation when submerged i.e H >0.5*D H = Head above center line of orifice D = Diameter And is there "any rule" such as this one for a Riser pipe (vertical drain). Thanks in advance!

2009年7月15日 · Both Metric class 10.9 and U.S. spec grade 5 are quenched and tempered for the heat treatment. The 10.9 class will utilize a low alloy steel (with some exceptions) ; the grade 5 is carbon steel. Take a look at SAE J429 and 1199 sometime--this will explain it all.

2007年6月14日 · The systems that I design generally do not exceed 40,000 GPD. These systems have never required any pipe greater than 4" in diameter. I have no use in specifying a whole range of pipe diameters that are "pressure rated" at a constant pressure. Especially when I can specify a material that is far more robust than any readily available SDR product.

2024年12月16日 · We have a 325MW renewable site that was studied with a Y-g 345kv / Delta 34.5kv 350MVA two winding transformer but we are kicking around the idea of changing it to a three winding transformer to reduce the secondary current. If we kept the impedance the same between the primary and the two...

2012年10月13日 · Our subcontractors want use phase array in liue RT, we are wondering the impact cost at the project, and the benefits in early finish at the project. In my opinion we just get improve in safety, we are not working at night shift, so the impact for man power is not a …
