EC3 axial calculation results expanded to show more detail. You can now manually select grade S460 hollow sections for BS and EC, and minor RHS sections for EC.
EC3 lateral torsional buckling calculations improved, now more accurate and efficient. EC3 interaction factors introduced into the utilisation check for combined bending and axial compression, conservative values used currently. Fixed an issue where EC3 axial buckling capacity results would differ from the utilisation values shown in step 2 for a minority of column loadcases. EC3 minor axis designs amended, now only available for RHS members. Tidied some small formatting glitches on the EC3 CHS shear, moment, and lateral buckling calculation sheet. Minor background updates and speed boosts.
Updated deflection calculations for two simply supported asymmetric point load loadcases.
Updated timber EC5 deflection calculations to ignore the floor vibration check when the 'Variable action EC' is set to 'Storage', 'Traffic' or 'Roofs'. Resolved an occasional issue where inadequate sections were showing a PASS instead of FAIL result on the printed calculation pages only.
Editing the Project, Element and Engineer boxes in step 3 is now improved.
Fixed a small bug causing imposed load values to carry over to column loadcases. Updated simply supported asymmetric point load deflection formula text, calculated values are unaffected.
Fixed an occasional error for column loadcases.
Fixed small bug for one propped cantilever loadcase affecting only the dimension input, not the design.

iPhone web app updated for all free access pages, free design app now provides all features of the desktop version including print and email features of the mobile safari browser.
Once added to the home page, the iPhone web app will load in full screen mode similar to a native app, printing will require exiting to the mobile safari browser.
FAQ page added.
Free design results printing updated across all browsers, note that IE8 will sometimes require printing from the Print Preview in order to print more than one page, this is an IE8 bug.
Also note that printing from Firefox can sometimes produce only one page where more are available, this is a Firefox bug. Printing from Chrome and Safari are recommended at this time.
Printed results are now kept on our server for a period of time, simply note the print-out url address for future reference, results will be removed from the server periodically.
Free design page minor bug corrected, required dimensions and loading units now update correctly.
Shear buckling check in EC3 updated. Shear effect on EC3 moment resistance updated. Compression buckling check for EC3 columns added. Axial load effect on moment resistance of EC3 I, H and rectangular hollow columns added. BS timber self weight effects removed from column designs. BS timber minimum bearing length of 35mm added.

Step 2 selection table now provides all available working sections. Steel: All adequate weights of each section size now shown in table, where previously only the lightest adequate weight was shown. Timber: All adequate grades of each section size now shown in table, where previously only the lowest adequate grade was shown.
Membership prices reduced. Updated to accommodate IE9 browser. fb likebox added.
Column loadcases in Steel to BS & EC added: Simple Columns,Encastre Columns,Cantilever Columns,Propped Cantilever Columns.
Further background preparation and test code for release 4.1 - column loadcases: Step 1 GUI disables timber floor and IL selections for columns.
