The steel shapes selected for inclusion in tables I thru XIV are those produced as or cut from U.S. comm

26、ercial standards. The sizes were chosen based on experience of actual use. 4.1.1 Properties. The properties indicated in tables II thru XIV are for rolled shapes. These are produced by one of the following methods: (a) By cutting off two sides of one flange of an I-beam even with the web, a tee-beam

27、 can be made having the same depth as the original beam (indicated as an I cut to a tee or I-T). (b) By cutting through the middle of the web of an I-beam to make two tees having a depth of one-half that of the original beam (indicated as a T). depths greater than 12 inches) a tee-beam can be made h

28、aving a depth which may vary from a maximum equal to the original depth of the beam to a minimum equal to the width of the flange (indicated as a tee cut from a wide flange or CF W). angle can be made having the same depth as the original channel (indicated as a channel cut to an angle or C-L). (c)

29、By off-center cutting through the web of an I-beam (for nominal (d) By cutting off one flange of a channel even with the web, an Weights and properties have been calculated from the theoretical dimensions which appear in the Manual of Steel Construction. Fillets or rounded edges have not been includ

30、ed in computing the weights and properties of all sections. Weights of all sections are computed on the bases that one cubic inch of steel weighs 0.2833 pounds. 4.2 Effective breadth of plating. The selection of an effective breadth of plating to be assumed acting in association with any shape (tee

31、or angle) is influenced by the yield strength and the modulus of elasticity of the material. This is calculated by the formulaqm t when E is the modulus of elasticity (lb/in2a), Fy is the tensile yield strength (lb/in2a) and t is the thickness of the plate. If the plating and beams have different yi

32、eld strength, the lower value yield strength is used in the formula. 4.2.1 Values. The values of effective breadth of plating in tables VI11 thru XI have been selected as 60t, 50t, 38t, and 35t for tee shapes and tables XII and XIII have been selected as 60t and 50t for angle shapes. These correspon

33、d to the actual values for MS (dot), HTS (50t), HY80 (38t), and HY100 (35t). 4.2.1.1 Tables VI11 thru XIII apply only if the calculated stiffener spac- ing is equal to or greater than the effective breadth of plating. Where stif- fener spacing is less than the nominal effective breadth, equivalent p

34、lating having the required area can be used by selecting an appropriate thickness. This method will result in only negligible error for most cases. . 5 / Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-Zbq 37 m 7777770 0038375 3 m MIL-HDBK-2

In order to avoid unrea- sonable combinations of beams and plates. the following limitations have been imposed on selecting shapes for attachment to plates whose thickness is greater than 0.1875 inches: (a) The neutral axis of
