A not so easy problem
A seemingly simple problem was posted in my Quora feed: or to put it more mathematically, what three positive integers satisfy the equation: It turns out the answer is not so simple. A full and detailed derivation can be found … Continue reading
ULS Design Functions 2.16
The ULS Design Spreadsheet has now been updated to Version 2.16, which can be downloaded from: ULS Design Functions The main new feature is the option to design for prestress loads applied to circular tanks. Due to axi-symmetric effects, when … Continue reading
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

Using ConbeamU
This post was prompted by a thread at Eng-Tips: https://www.eng-tips.com/viewthread.cfm?qid=501339 The beam analysis functions in the ConbeamU spreadsheet allow for the use of any SI units, or any non-SI units found in the long list included with the spreadsheet. I … 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
