The problem is now solved though the font in the main window (bolted shape form) had to be changed problems in saving load table values in files with some special number formats now solved other minor bugs resolved and minor enhancements implemented version 15.02.01.06 released on August 12th, 2015 French language option added Round and rectangular tubolars as columns added in several modules br9 module can now take as braces also round and rectangular tubes, I shaped members and 4 angles elastic calculation method for welds according to AISC slightly modified in case of double fillets in some situations the import from Sap2000 was not taking the correct end joint on the beam, now corrected width of member HEA120 corrected in the database from 110mm to 120mm version 15.02.02.01 released on August 24th, 2015 in br9 module (bug introduced in version 15.02.01.06 ) results might not display under certain conditions: now solved version 15.02.03.05 released on October 30th, 2015 formula for checking tying force modified to include bending moment effect too some numeric formulas added in repors also according to other standards (previously only AISC and CSA) through plates and double sided options added also for RHS, CHS RHS sections now possible in module cb8 (base plates) Formula 9-30b in AISC manual used to calculate prying action in SCS according to ASD uses in SCS now 1.67 as Omega instead of 1.5 as in previous releases other minor bugs resolved and minor enhancements implemented version 15.02.04.01 released on November 9th, 2015 French translation improved other minor bugs resolved and minor enhancements implemented version 16.00.00.12 released on February 7th, 2016 Base plate calculations for the EC method when external bolt distance is larger than column width now improved General options choices that influence design are now visible in the single modules and can be overwritten import from Sap2000 version 18 now available in module br9 the position of bolts of lug angles in the sketch was not correct under certain circumstances (bug introduced with versions 15.02.0106) in module br9 the sign of weld eccentricities have been revised in some instances (it might change some results comparing to previously saved files) in module br9 the eccentricities (if any) of UFM method now considered in more correct way (some calcs in previous versions might change) block shear of angle shapes that are flipped or in a butterfly/quadruple configuration now corrected (if angles are flipped and bolts are not symmetrical block shear calcs in previous versions might be slightly unconservative) in module br9 now it's possible to offset the brace from its axis. Now also the eccentricity of the secondary member and the bolt group are taken from the axis of the brace (axial action will therefore add bending moment if eccentricity is different from zero; it might change some results comparing to previously saved files) plate buckling according to AISC now it's less conservative (Qs = 1 as per table E1.1 of the specs, that is now ch. E7 is not taken into account for plates and only ch. E3 is considered) in the General options is possible to set the formulas (visible when the mouse is over them) in numeric form instead of literal other minor bugs resolved and minor enhancements implemented version 16.00.01.08 released on April 10th, 2016 import and export from Tekla of moment connections (module em3) is now possible now it's possible to input plates and channels as secondary members in modudules fp1, fp2, qs5, qs6 now it's also possible to input plates as secondary members in modudules xl1 and xl2 moment connections according to EC were calculated with alternative method (method 2) even though the option is not selected (bug introduced in version 16.00.00.12) prying acion calculation according to AISC now enhanced (previous version results were slightly more conservative when shear was present) to consider only the available tensile strenght of bolts (that is tensile strenght of bolts is reduced considering the strength taken by shear) in module kx3 calculations, now the gusset plate area is included when checking shear and axial force of the secondary member in the vertical connection in module kx3 the gusset plate can be calculated separately (this allows to input a different bolt configuration for the vertical connection) in module kx3 the column can now be selected as pipe or RHS other minor bugs resolved and minor enhancements implemented version 16.00.01.09 released on April 11th, 2016 a couple of bugs resolved in module kx3 version 16.00.02.11 released on May 26th, 2016 from the initial bolt shaped form it is now possible to open (click 'i' in the top right corner then 'report utility') a form where a group of files can be specified in order to have SCS automatically generate the reports the Sap2000 import macro now translates the units in Sap into the units of SCS, therefore it does not change the units in SCS as it used to do before; then the forces are added to the empty fields of the force input table of SCS (previously the existing combinations in SCS were deleted) block shear resistance calculation for beams improved when a reinforcing plate is welded (now the vertical area between bolts include the reinforcing plate thickness) some bugs resolved when displaying numeric formulas after changing standard a bug for weak axis moment calculation in module em3 (moment connection) found, affecting checks and warning displays in some particular conditions other minor bugs resolved and minor enhancements implemented version 16.00.02.13 released on May 27th, 2016 a bug in the multiple report generation now solved version 16.01.00.00 released on June 22nd, 2016 the splice module (SP4) had an error in calculating the force acting on flange bolts because of the applied moment (error introduced in version 16.00): it was considering it zero independently on the moment other minor bugs resolved and minor enhancements implemented version 16.01.01.01 released on July 25th, 2016 the Sap2000 and Staad import of base plate loads was only importing one joint even though multiple joints were selected (only in module .cb8) in modules em3 and ap7, the option "Axial force modifies Mmaj" was not working correctly. This option is turned on by default, though not visible, when the selected method is "Aisc design guides" so calculations with this method where axial tension is present in addition to moment may be incorrect (uncoservative results) added some sections: Indian ISWB and ISHB, Metric channels C and MC (mostly used in Canada), corrected HEA120 width that in some DB was 110mm instead of 120mm added Australian bolt class 8.8 other minor bugs resolved and minor enhancements implemented version 16.02.00.00 released on September 24th, 2016 AS4100 standard now available for comments Load import from Etabs 2016 added Tekla import - export available also for module we1 It now targets Tekla Structure 2016 version staggered bolt feature added in module sp4 in module sp4 some plate block shear values might have been slightly incorrect in previous versions other minor bugs resolved and minor enhancements implemented version 16.03.00.02 released on December 7th, 2016 .Net framework 4.5 now targeted AS4100 officially added as a standard when the selected method for bolt tension was "AISC, Neutral Axis thru Center of Gravity", an unconservative error was introduced in version 16.00.01; the bug is now solved Calculation of the critical moment of members for buckling resistance now corrected; this may have brough some (slightly) unconservative results related to member bending resistance in some situations (if buckling is governing) Some shear lag coefficients (beta 2 and beta 3 in Eurocode, coefficient for effective net area in CSA S16) modified and now the corresponding check might be more conservative Gost-sto-20-93 Russian profiles added in the database BS #42 method to calculate base plates (module .cb8) now integrates also the pin model method presented in #41. The limit between pin connection and moment connection has been imposed as the critical eccentricity as defined in #22 EC #00 method to calculate base plates (module .cb8) now gives a higher concrete compression when there is an eccentricity given by a moment BS #41/#42 and AISC DG #22 methods base plates (module .cb8) now give a higher tension value in anchors when the conditions are no compression and little eccentricity import from Sap2000 v19 added For Snip calculations, now it is possible to choose between standard #70 (SNIP II-23-81, 1981) and #71 (SP16.13330.2011, 2011) other minor bugs resolved and minor enhancements implemented version 17.00.00.00 released on Febraury 2nd, 2017 Algerian standard DTR-BC-2.44 officially added as a standard Japanese standard SSSCS, JSCE

load import now solved (module cb8 had errors when importing multiple joints; other modules might experience bugs if the option 'each joint will have its own combinations' was selected and some joints had compression while other tension) (bugs introduced in version 17.01.00.07) other minor bugs resolved and minor enhancements implemented version 17.03.00.00 released on July 28th, 2017 in module ap7 now round tubolar (round HSS) connections are available tie force check throug warning/error in the message box now available in xl2, fp2 and qs6 tie force check by means of DG 29 method now

(restarting SCS and Tekla) from one Tekla version to another In moment connections designed according to Eurocode and similar standards, now the column web transverse tension resistance adds up the web resistance with the transverse stiffener resistance (previously only the latter ones were considered when present) Some changes applied to the resistance of base plates according to EC method when anchor bolts are working in prevalent tension (previous results were more conservative) It is possible to generate resistance domains for most of the connections; moment resisting connections like moment end plates, base plates, apex and welded connections will generate 3D domain (V, N, M) while shear connections 2D domains (V, N) Moment connections calculated according to EC can now be classified in the "Stiffness" result tab as rigid, semi-rigid or nominally pinned weak axis shear formula corrected (previous incorrect formula was giving more conservative results) other minor bugs
