Why are bending check results for rectangular columns different between Tedds and Tekla Structural Designer?

Question Why are bending check results for rectangular columns different between Tedds and Tekla Structural Designer? I notice for example the NA depth is different. What method does Tedds use vs Tekla Structural Designer? Answer The method specified in equation 5.39 of EC2, which is used in Tedds, is a simplified approach with limited application, whereas Tekla Structural Designer uses a general and more accurate approach determined from first principles which can be applied to a wide range of cross sections. In Tekla Structural Designer the method of checking whether the reinforcement in

I cannot calculate within Tedds - The message "Failed to get the active instance of Word" is displayed

Question When running any of the calculation commands, an error is reported which prevents me from calculating. How can I resolve this? Answer This issue often occurs as a result of upgrading from a 32bit version of Office to a 64bit version. However, the problem can also manifest itself in several different ways, because there are several different areas of the software which rely on the Microsoft Word integration working correctly and if it has become corrupted on a users system then various features may not work. These include the following: Calculating in Tedds for Word does not work

When using the Snow Loading (EN1991-1-3) calculation and inputting Snow loading - "Site Details" what does the Zone refer to?

Question When using the Snow Loading (EN1991-1-3) calculation and inputting Snow loading - Site Details, what does the Zone refer to? There are no tooltips or references to assist.    Answer After inputting the Location, an Altitude and Zone are automatically calculated for you. Note these can be user adjusted. The Altitiude and Zone are used in the calculation for the Characteristic ground snow load sk.   Reference needs to be made to the UK National Annex and Clause NA.2.8. The Zone is then determined from Figure NA.1 Characteristic ground snow load map

How do I change the precision of the results in Tedds?

Question How do I change the precision of the results in Tedds? Answer Calculations written and included in the system library by the Tedds team are typically written with a specified result precision i.e. =?F3 where F denotes Fixed format with 3 decimal places. It is not possible to over-ride these values. Further infomation on "Results fields" can be found in the Help system. For calculations written by yourself or where result precision has not been set, then the precision of the result in Tedds is determined by a setting found in the Tedds options.

Why is a reduction factor (RF) applied to all columns in Tekla Structural Designer and not the Tekla Tedds "RC column design to EC1992" calculation?

Question Why is a reduction factor (RF) applied to all columns in Tekla Structural Designer and not the Tekla Tedds "RC column design to EC1992" calculation?   Answer Tekla Tedds uses a different and more approximate biaxial bending check method to that of Tekla Structural Designer, meaning that a 10% reduction of the concrete strength is not applied in the Tedds software for rectangular sections. Note that the 10% reduction (displayed in Tekla Structural Designer results as a reduction factor RF = 0.9, see screenshot above) comes from the following Clause and rationale: EC2 section 3.1.7(3

Is there a difference between the main bars and the additional bars in the beam "RC 2D Analysis and Design calculation"?

Question Is there a difference between the main bars and the additional bars in the beam "RC 2D Analysis and Design calculation"? Answer The bottom reinforcement for the central zone of the beam is taken from the bottom bars in the first zone. This then cannot be edited for the central span, ie. if 2 x H16 are specified for the bottom bars in the first zone, this will be carried into the central zone and will not be editable.   If we then increase the number of bars in zone 1 to 4 x H16, this value will now be carried into the design of the bottom bars for the central panel.   If we wanted

I cannot launch Tedds - Error 3 or Error 5 is reported within the Status page of the License Manager. How can I resolve this?

Question Tekla Tedds appears to "hang" when attempting to launch and Error 3 or Error 5 is displayed within the Status page of the License Manager. How can I resolve this? Answer The Sentinel RMS License Manager Service has stopped on the server – check that this service is running on the server. Run a ping test of 8000 bytes from the client machine to the server to confirm that communication is possible - a ping test will not be blocked by the same hardware/software that is blocking the License Service.

Commuter licenses - Incorrect number of In Use licenses

Why does my Commuter In Use count show a number larger than the number of license we have preventing any other user from claiming a license? Background information If a server license has been commuted, restarting the Sentinel RMS License Manager service on the server (or rebooting the server) may increase the number of licenses that have been checked out, preventing any other user from claiming a license. The issue is not a corruption of the underlying license data but how the Sentinel RMS service interprets this data. The fault lies with the service in the lsrvnt.exe. Prevention In normal

I cannot activate my Tekla Tedds PAK - The message "The product activation key you have entered is not a local computer locked license product activation key" is displayed. How can I resolve this?

Question I have installed Tekla Tedds but when I try to activate my Product Activation Key (PAK) the message "The product activation key you have entered is not a local computer locked license product activation key" is displayed.  Answer If the PAK code you have received begins with "42334" or "52334" then this is a Server (network) license. This means that the license can be activated (and used) on one machine (this machine will become the 'license server'), and any other machine connected to your network can also use the license (see further below for information on how to do this).

Question When attempting to launch Tedds the License Manager launches instead, stating Error 25 within the Status page. Answer Upgrade the Tekla License Service on the License Server. This can be downloaded from our website here and must be installed onto the License Server with the following options (include the third option if Tedds is also used on the license server):   Due to significant changes to the current version of the Tekla License Service, this upgrade is required on the license server to enable the use of Tedds 2017 (or any product downloaded after March 2017).

I cannot launch Tedds when connecting over a VPN. What changes can I make to resolve this?

Question When I try to launch Tedds when connecting across a VPN, the License Manager launches instead, displaying errors. This issue does not occur when connecting over my local network. What changes can I make to resolve this? Answer When I attempt to use Tedds across a VPN, connection issues between the server and client machines may occur, preventing Tedds from launching.  A common cause of this can be the firewall on the server and/or the client machine(s) blocking the License Service and possibly Tedds/Structural Designer due to IP packet encryption across the VPN.

Since installing Tekla Tedds 2017 Windows seems to sometimes restart unexpectedly - are they connected?

We have had isolated reports, that under some specific circumstances, that after installing Tekla Tedds 2017 some Windows 7 machines are experiencing an intermittent issue whereby the machine reboots shortly after the first boot of the day. Diagnosis Unfortunately the reboot is a failure of Windows at the lowest level and therefore there is no information logged in the Event log or captured by a MiniDump. We have managed to track down the issue to be related to a Compatibility update for Windows 7 deployed by a Microsoft Update. The update creates a scheduled task which performs diagnostics
