Cracking and tension field action in composite beams [PDF]
Two aspects of the behaviour of uncased composite 'T' beams of steel and concrete are considered. Flexural cracking in the reinforced concrete slab was studied by subjecting seven 350-mm deep composite beams to hogging bending moment.

Rapid design of steel monosymmetric plate and box girders
, 2010 This thesis deals with the design process for steel plate girders and box girders. The design of plate girders is quite prescriptive. A more fundamental approach is required for the design of box girders.
