I have increased the reinforcement in my Hollow reinforced masonry retaining wall. Why is the moment resistance decreasing?

Question I have increased the reinforcement in my Hollow reinforced masonry retaining wall. Why is the moment resistance decreasing? Answer The Moment resistance for a Hollow reinforced retaining wall is calculated as the lesser of Asr,prov x fyd x z , where Asr,prov is the reinforcement provided to the wall, fyd is the Design yield strength And; 0.3 x fd x d2 , where fd is the design compressive strength of the masonry and d is the depth to the tension reinforcement. This would indicate that increasing the reinforcement should increase the moment resistance in the wall for the first term.

When I try to use the User Interface command, the Manage User Interface dialog appears, but clicking any button freezes the program. How can I resolve this?

Question When I try to use the User Interface command, the Manage User Interfaces dialog appears, but clicking any button appears to freeze the program. How can I resolve this?   Answer To allow us to rectify the issue we need to stop the Tedds Interface Designer process. Run Task Manager (right click the Windows taskbar and select Task Manager). In the Processes tab, Locate Tedds Interface Designer (32bit), select it and then click End task.   We have discovered that there is a conflict between the Tedds Interface Designer and the Revit Accelerator process. To resolve, we need to select the

When I attempt to run the Tedds Batch Design calculation, Tedds keeps taking the windows focus. How do I prevent this from happening?

Question When I attempt to run the Tedds Batch Design calculation and then switch to another program i.e. email client to work on something else, Tedds keep taking the windows focus so I cannot do anything else. How do I prevent this from happening? Answer Within Tedds for Word, you can access the Tedds ribbon tab > More > Tedds Options    Within Tedds Options, you can then turn off the Progress log window by setting the Calculating > Progress to None, so that the Progress log does not take the focus at the end of every batch design iteration.

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 error message "Failed to get the active instance of Word" or "An error has occurred whilst calculating, the document cannot be updated" 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 system then various features may not work. These include the following: Calculating in Tedds for Word does not work Executing

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.

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

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
