852094
Analysis/Design Engine - The steel design routines that use the details of the yield and ultimate strengths from the material definition, have been updated to ensure that it is now possible to assign different values of FY (FYLD) and FU in a design parameter block, along with members that have these determined from the material definition. This applies to the following design codes, AISC 360-16, IS800 2007 LSD/WSD, AIJ 2002/2005, AISI 2016.Note that this was previously documented as a known Issue.
862709
Analysis/Design Engine - The output for a steel design to the Canadian steel design code CSA S16-14 code has been updated to clarify the details of the units used in the output which is either KNS and MET, if the current length units are defined with a metric unit, or KIPS and FEET if the length unit is in English units. Multiple reports of this guidance previously reported have been reduced to a single instance per CHECK/SELECT command.
865805
Analysis/Design Engine - The determination of the effect of the accidental torsional moment, if the option has been included in the application of a static seismic load (Mi = Qi × edi at floor i), has been updated to address an issue which was determining the moment using a value of Qi^2 instead of Qi.
865842
Analysis/Design Engine - The design for the seismic provisions in an AISC 360-6 code, (i.e. to AISC 341-16), has been corrected as the overstrength factor was incorrectly determined if the properties of the material are defined using the parameters FYLD and FU rather than from a standard grade (i.e. using SGR parameter)
867847
Analysis/Design Engine - The method used to determine the Raleigh Frequency has been updated to ensure that the routine is fully initialised which was otherwise causing the analysis to fail with a message:- ** ERRORS IN SOLVER **
872271
Physical Modelling Workflow - The five dynamic options that were omitted in release 22.10.0.153 have been reinstated. The options are, Calculate Eigen Solution, Eigen Method, Set Number of Modes, Shift Modes and Set Shift Frequency.
872540
Analysis/Design Engine - The routine that reports the forces on plate elements when a response spectrum load case that includes the MISSING MASS option has been updated to prevent the analysis from terminating due to attempting to access invalid memory.
874956
Analysis/Design Engine - The AISC 360-16 design checks on user defined tubes which have been defined with the local Y axis stiffness greater than the local Z (i.e. ZD is defined greater than YD), has been updated to prevent the LTB check to be reported as infinity. Although this is not in line with the STAAD requirements that the local Z axis should be the stronger axis, the member will checked with LTB for the actual weaker axis.
875122
Analysis/Design Engine - The AISC 360-16 design routine to design of members defined as cantilevers (i.e. using the parameter CAN 1) when included in a block that exceeds 1000 members, has been updated to prevent an internal reference failure.
875476
Analysis/Design Engine - The routines used to check angle profiles defined with the reverse angle option (i.e. RA) to the Canadian steel code, CSA S16-09 and CSA S16-14 have been updated to catch an issue that would cause the analysis to terminate. The situation required the member to be checked to multiple load cases such that a load case induced only axial forces and then is followed by a load case which subjected the member to both axial and bending forces.
892818
Analysis/Design Engine - The steel design routine that performs the checks to the CSA S16-19 design code has been updated to ensure that if load cases have been defined in strength/serviceability envelopes, used to determine which type of checks should be performed, and both envelopes defined in a preceding LOAD LIST, then the checks for serviceability are restricted to only those cases that have been classed as such. Previously, serviceability checks were also performed on strength classified load cases which could result in a conservative design.
