ConbeamU update

Posted on September 28, 2021 by dougaj4

I recently discovered that the continuous beam function from the ConbeamU spreadsheet was giving incorrect results for cantilevers at the left hand end, if the cantilever had more than one segment and no point loads. The corrected version (Rel 4.16) … Continue reading →

Deflections and Moments in Rectangular Plates

Posted on August 9, 2020 by dougaj4

Following a question here I have compared tabulated coefficients for deflections and bending moments in a rectangular plate with results of a Strand7 analysis using 8 noded plate/shell elements.  The results are summarised below, and in a spreadsheet which also … Continue reading →

Dancing Pendulums Revisited

Posted on April 12, 2020 by dougaj4

I have previously posted on Dynamically Defined Dancing Pendulums, using the Strand7 FEA program to generate the motion of a series of pendulums of varying length.  I have now updated that video using the latest Beta version of the program (Rel … Continue reading →

3D Frame with zero stiffness hinges

Posted on April 9, 2019 by dougaj4

The previous version of 3DFrame allowed for spring releases at beam ends, but if the release stiffness was entered as zero it was treated as a rigid connection for that freedom.  Effectively zero stiffness releases could be modelled by entering … Continue reading →

3DFrame update

Posted on May 31, 2017 by dougaj4

The update to the Glob_to_loc3 and Loc_to_glob3 functions (and associated functions) has now been transferred to the 3DFrame spreadsheet, which will now give correct results when beams are defined in the global negative Z direction.  The revised spreadsheet (including full … Continue reading →
