It is now taken as a default value of 0.75 in calculating Ta.Ī) 08 The IS 1893 seismic provisions have been enhanced with IS1893 Part 4, 2005Ī) 09 The Eurocode 3 steel design module EN has been enhanced with the Malaysian National Annex. (see section AD.2007-09.1.2 for more details)Ī) 07 The IBC 2006 loading module has been updated to ensure that if an input of 'x' has not been specified, then this was taken as 0 which would create potentially conservative results. Additionally it is now possible to define a different material to the top flange cover plate of a wide Flange user table section using a modular ratio. It is now possible to define cover plates of different dimensions on the top and bottom of the profile by using a TB parameter. The correction was done in the implementation of equation 6.12.2.2.2-1Ī) 05 The Indian steel design code IS800:20007 has been updated to ensure the classification of wide flange sections under pure axial load is reported as slender when the semi-compact limit is exceeded.Ī) 06 The scope of adding cover plates to standard wide flange sections has been enhanced. This has been changed so that it now follows the provisions of section G2(b).Ī) 03 The AIJ steel design module has been updated to ensure that when checking for maximum moments and determining stresses, the values are based on the full value rather than the integer version of the numbers which had been used previously.Ī) 04 The AASHTO LRFD design module has been updated in correcting the calculation of bending moment capacity for tube sections. This has been updated to use a calculated beta-w as per clause 4.3.6.9Ī) 02 The AISC 360-05 design module has been updated for design of rolled wide flange sections when h/Tw > 2.24*sqrt(E/fy), Cv was set to 1.0, Phi = 0.9 and Omega = 1.67. The calculation of beta-w was taken as 1.0 for all section classifications.
(A) Issues addressed in the Analysis/Design engine (18)Ī) 01 The BS5950-1:2000 design module has been updated for the design of double angle sections.
