Composite beams - Shear connection part 3
To explain the design of shear connection in continuous composite beams, with special emphasis on hogging moment regions.
The aim of the lecture is to explain simply the basis of designing full and partial shear connection in continuous composite beams, mainly dealing with the connector distribution in hogging moment regions. The greatest care must be taken regarding the validity of plastic cross-section behaviour. For critical cross-sections in Class 1, a general method is developed and illustrated by examples. For critical cross-sections in Class 2, an outline is given using a simplified method.
This lecture describes the design of shear connection in continuous composite beams. This is discussed mainly with regard to a practical method for determining the connector distribution along the shear span in the hogging moment region. The use of partial shear connection in a continuous beam is considered. This is a complicated topic which must be related to the validity of plastic theory and take into account the increased risk of local flange buckling at internal supports.Read more
