2022年5月27日 · AISC requires the use of hc/tw to check the compactness of a web subject to flexure for singly symmetric I-shapes per Case 16 of Table B4.1b. See below. hc can be greater than h. hc increases when Sxt > Sxc and decreases when Sxc > Sxt.

2024年1月9日 · AISC's Appendix 6, Section 6.3, the commentary says this: Beam bracing must control twist of the section, but need not prevent lateral displacement. Both lateral bracing, such as a steel joists attached to the compression flange of a simply supported beam, and torsional bracing, such as a...

2022年5月27日 · Over the last two years, I developed a steel beam-column design aid according to AISC 360-22 for my M.S. civil engineering non-thesis project. The design aid (built in Excel) can be used to analyze and design shapes with original, reduced/corroded, and reinforced/built-up section properties...

2012年9月11日 · Regarding the Load Level for Notional Loads: Notional loads are applied as a percentage of the design loads. So, if you are using factored load combination (i.e. 1.2DL + 1.6LL) the notional load can already be considered to be facto

2023年12月18日 · This is from AISC 360-16 "Single angles with continuous lateral-torsional restraint along the length are permitted to be designed on the basis of geometric axis (x, y) bending. Single angles without continuous lateral-torsional restraint along the length shall be designed using the provisions for principal axis bending except where the ...

2018年1月15日 · I am using AISC 360-05 for the design of a tee in flexure, as per Chapter F9. I understand sections F9.1 and F9.2 but am having trouble confirming what F9.3 does / doesn't cover. Firstly, "Sxc is the elastic section modulus referred to the compression flange".

2022年2月10日 · Also: When reading the Section E7 (local buckling) of AISC 360-10, it says: " Fe = elastic buckling stress, calculated using Equations E3-4 and E4-4 for doubly symmetric members, Equations E3-4 and E4-5 for singly symmetric mem- bers, and Equation E4-6 for unsymmetric members, except for single angles with b/t ≤ 20, where Fe is calculated ...

2022年1月24日 · Plan on reviewing AISC 360: chapter E (Compression), chapter F (Flexure), chapter J (Connections) and any and all chapters and appendix related to stability. For AISC 341 – B (General Design), D(connection), E (Moment-Frame), and especially F (braced frame/shear wall). Unfortunately, parts of documents that have been altered, have not been ...

2014年7月14日 · I believe a building or non-building structure can be designed according to the provisions in AISC 260 in seismic design category D if the R value is less than 2.5? I can only find references that indicate Seismic Cat D-F require detailing per …

2010年1月12日 · In reading AISC 360-05 (13th Edition) I'm a bit confused on Chapter J: Design of Connections, section J2.4 Weld Strength.
