Abel Selaocoe

Last Saturday I saw cellist Abel Selaocoe perform with the Australian Chamber Orchestra, performing a mixture of classical works and his own unique compositions. He captured the audience and at the end of the performance received an ovation the like of which I have never seen before.

From his web site: https://www.abelselaocoe.com/

South African cellist Abel Selaocoe is one of the most captivating performers on the world stage today. With an irresistible energy, he has taken the world by storm since bursting onto the scene in 2021 with his BBC Proms debut. Whether with symphony orchestras, in iconic club venues or at major mainstream festivals, Abel combines virtuosic cello and vocal performance with improvisation and sweeps audiences along in captivating shows which blaze with creation, sending audiences home on a high.

Abel grew up in Sebokeng, where he first began learning cello with his brother at the African Cultural Organisation of South Africa (ACOSA) in Soweto. Abel’s affinity for the cello became quickly apparent and he continued his studies on scholarship at St John’s College before moving to the UK where he found a musical home at the Royal Northern College of Music in Manchester. In Manchester, he met the musicians who are now his most regular collaborators, and this has led to the formation of his bands, Chesaba and the Bantu Ensemble.

New Links

My Blogroll (bottom of the right-hand column) is badly in need of updating, but the link below has a list of 60 currently active Excel blogs and websites:

60 Best Excel Blogs and Websites in 2025

Those at the top of the list include several long running but still active sites, as well as several that I had not heard of before.

And scrolling down to number 26 we find none other than Newton Excel Bach 🙂

ULS Design Functions-biax 0.08

I have just uploaded a new version ULS Design Functions-biax, which can be downloaded (together with the uni-axial version) from:

ULS Design Functions.zip

The main changes are added code parameters from Eurocode 2:

Detailed output for a specified load and neutral axis angle is as in previous versions:

There are also functions that will generate various interaction diagrams:

For more details and examples see: Biaxial Bending Update.

3DFrame-NLGeom

The VBA version of the 3DFrame spreadsheet has now been updated to allow geometric non-linear effects to be included. The new version can be downloaded from:

3DFrame.zip

For more details of the VBA 3DFrame see 3DFrame update, and for the Python version, which also includes non-linear materials analysis and combination of multiple load cases see 3DFrame-py-comb.

The input for the new 3DFrame-NLGeom spreadsheet allows for setting the maximum number of load iterations and the relative displacement tolerance.

The output format is the same as previous VBA versions, except the number of iterations and maximum displacement error are now shown.

In the screenshots below bending moment and deflection results for a portal frame with very high vertical and horizontal loads are compared with Strand7 results, also allowing for geometric non-linear effects, with linear elastic material properties. The results are in very close agreement for all cases.
