CSI.Bridge.2016.v18.1.0.1227 Changes from v18.0.0 (Released 2015-10-30) Miscellaneous Enhancements Implemented * Incident Description 85446 The version number has been changed to v18.0.1 for a new minor update. User Interface and Display Incidents Resolved * Incident Description * 85432 An incident was resolved in which the 64-bit version of the program could take a minute or more to launch on certain machines. This is a result of Microsoft's JIT (just-in-time) compiler and not a bug in the software. Not all systems are equally affected, and newer versions of the Windows (8.1 and 10) tend to be less affected, especially if Windows Updates are current. A new tool, CSiNativeImageGen is available to 'precompile' the software after installation, prior to use. In most cases this should resolve the slow startup time, as well as speed up the displaying of forms. CSiNativeImageGen is available in the installation folder and must be Run As Administrator. Information on the use of this optional tool is provided within CSiNativeImageGen itself using t he Help command, and by searching the CSI Knowledge Base at wiki.csiamerica.com for 'native image generation'. Loading Incidents Resolved * Incident Description * 85382 85534 An incident was resolved in which the assignment of area loads to frames was actually being assigned as area uniform loads instead of area loads to frames. The analysis results would reflect the area uniform loads, and usually no load was lost. 85607 An incident was resolved where the diaphragm widths in X and Y directions were flipped when calculating the torsion due to specified additional eccentricity for response spectrum cases. Frame Design Incidents Resolved * Incident Description * 85333 85386 An incident was resolved in which the steel frame design results could be incorrect and/or the rightclick design details were not able to be viewed when using the 64-bit version on certain machines. When results were available they could appear reasonable even if they were not correct. All steel CSiBridge 2016 v18.0.1 2015-11-12 Page 2 * Incident Description frame design codes could be affected. This only affected v18.0.0, 64-bit. The 32-bit version was not affected. * 85387 An incident was resolved in which the Eurocode 3-2005 steel frame design was incorrect for box sections. Models with box sections designed in v18.0.0 should be redesigned. No other versions were affected. * 85520 An incident was resolved for AISC 360-10 steel frame design in which the compression capacity of box, pipe, rectangle, circle, general, and section designer sections was being taken equal to the tension capacity, ignoring the compression capacity due to flexural buckling. This error could overestimate the compression capacity of these type of sections. This only affected models designed in v18.0.0. Results Display and Output Incidents Resolved * Incident Description 85453 An incident was resolved in which the graphical display of results on a limited selection of the model was taking extra time to display. This was a performance issue only and did not affect results. 85587 An incident was resolved in which the date on the report cover page was not correct. Data Files Incidents Resolved * Incident Description * 85367 An incident was resolved in which trying to import frame section properties from a *.pro library file would generate an abnormal termination when the *.pro file was located in a folder without write
