Per Tveit is Docent Emeritus at Agder University, Grimstad, Norway.  He graduated from The Technical University of Norway in Trondheim in 1955. He was awarded his dr. ing. from the same institution in 1964.

He has worked in private firms for 5 years. The rest of his professional life he has been in institutions of higher learning in Norway, Denmark and the USA. This gave more time for research.

When working on his master’s thesis he came up with the idea of the network arch. The network arch is defined as an arch bridge where some hangers cross each other at least twice. It has been the main theme of his research ever since.

In the early sixties he was allowed to build network arches in Steinkjer and Bolstadstraumen in Norway. They have lived up to his predictions and expectations.

The idea has spread. Recently network arches have been built in about 27 countries. Some of the places that network arches have been built can be found on this map that the author is still working on: www.tinyurl.com/nettverkbogekart

Per Tveit has travelled around the globe 4 times and has given lectures on network arches in 50 countries.
