## Secondary moments in prestressed beams with FEA-2

Following the first post in this series, this post compares friction losses in prestressing cables as defined in the Australian Concrete Structures Code (AS 3600), compared with a cable modelled with contact elements in Strand7. The example used is based … Continue reading

## Secondary moments in prestressed beams with FEA

Secondary (or hyperstatic) bending moments occur in prestressed beams that are continuous over internal supports, or have other redundant support conditions. Any eccentric prestress force will cause a beam to deflect, and if these deflections are restrained at internal supports, … Continue reading

## ConbeamU update

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

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

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
