However this was correctly processed for all other codes such as IBC and IS 800.Ī) 05 The routines that design concrete members has been updated to correctly process the forces which result form load cases that include response spectrum definitions which previously did not correctly account for the nature of the internal forces. with other tapered members rather than individually), which could result in an incorrect final design as the memory used to store the results was getting overwritten.Ī) 04 Seismic weights defined in a FLOOR GROUP failed to be processed for NRC, NTC and Turkish codes. Now the check for selecting the bar size will include the spacing check as well as the forces check to determine the most efficient solution.Ī) 03 The design of tapered members to the AISC 360-05/10, IS800-2007 and CSA S16-09/14 codes has been updated to address an issue which occurred when their design was included in a batch command (i.e.

However, this number may then fail on the spacing checks and thus the larger number of smaller bars could meet the requirement. Previously the size of bar was selected based on the minimum area of steel provided which could be a small number of large diameter bars.

(A) Issues addressed in the Analysis/Design engine (11)Ī) 01 The old AISC LRFD design code (pre AISC 360) has been updated to ensure that the design of double channels arranged in a back-back alignment are specifically prevented as these are not covered by the design processes currently available.Ī) 02 The Indian concrete design code IS456 (including IS13920) has been updated to improve the determination of bars required.
