18、 based on minimum shade air temperatures of 5 c and 15 c respectively, are given in Table 2 and Table 3 for the most common conditions of use (see Table 2, footnote A for limitations). The maximum thicknesses are derived from requirements given in BS en 1993-1-10, including its national Annex, and t
19、he extension of the range of reference temperatures in Table 1 of this Published Document. NOTE The minimum temperatures in Tables 2 and 3 are expected to cover the majority of future steel building locations in the UK. For more specific data on minimum shade air temperature distributions in the UK,
20、 see NA to BS EN 199115. In cases where lower temperatures apply, the use of JR subgrade in external applications may be restricted (see NA to BS EN 1993110:2005, Table NA.3). The procedure for use of Tables 2 and 3 is as follows: identify potential notch inducing details on member/component a) bein
21、g checked and classify in terms of T RDvalue (see nA to BS en 1993-1-10:2005, NA.2.1.1.2). c alculate the maximum tensile stresses at the details concerned in b) terms of ed /f y (t) according to selected steel grades and element thickness. Select relevant column in Table 2 for each detail according
22、 to c) T RDand ed /f y (t) values (each column corresponds to a particular value of adjustment to the reference temperature). c heck the conditions assumed in Table 2, footnote A. in the event d) that any of the four parameters are not equal to zero for any detail, move from the relevant column to a
23、 new column to the right. The number of column moves should be one for each 10 c adjustment of T that is required. using the detail which relates to the column which is furthest to e) the right for the member/component being checked, select the lowest c harpy subgrade, appropriate to the intended st
24、eel grade, that has a permissible thickness equal to or exceeding that of the member/component element thickness at the controlling detail. in borderline cases it is valid to interpolate between values of f) ed /f y (t) and thickness in adjacent columns to determine the limiting thickness. EXAMPLE T
25、ransverse welded stiffener detail in internal beam 762 267 197UB to BS EN 100252:2004, Grade 275 with ed= 190 N/mm 2 . Conditions in Table 2, Note 1 apply. Flange thickness = 25.4 mm f y (t) = 265 N/mm 2 ed /f y (t) = 0.72 Therefore T RD= 0 C and ed /f y (t) 0.5 (see Table 2). Use seventh column in
26、Table 2. Maximum permissible thickness for S275 JR = 40 mm. Therefore JR subgrade is acceptable.PuBliSheD DocumenT BSI 2009 3 PD 6695-1-10:2009 Table 2 Maximum thicknesses for internal steelwork in buildings for T md= 5 C A) Detail type Tensile stress level, Ed /f y (t) appropriate to stress level a
