Test on composite beam to improve Eurocode 4
The Steel Construction Institute (SCI) along with a number of universities, including the University of Bradford, has won an EU project aimed at developing more realistic and economically efficient shear connection rules for modern long span construction.
A key part of the project is to test composite beams with degrees of shear connection that are lower than currently permitted by Eurocode 4. With this objective, a 15m span composite cellular beam will be load-tested at Bradford University in October. It has a ratio of bottom to top flange areas of 2.5 and has regular 425mm deep openings with an elongated opening at mid-span.
This is said to be the longest composite beam test ever carried out. Shear connectors are placed at 300mm intervals along the beam in the ribs of the profiled decking and the calculated degree of shear connection is 33%.
SCI will organise a seminar at Bradford to coincide with the test, and delegates will be able to witness the final load test. The Seminar is on the afternoon of 15 October. Members wishing to take part in the Seminar are invited to contact Prof Mark Lawson at firstname.lastname@example.org.
