Dr Robert Vollum joined Imperial College as a Lecturer in the early 1990s following a decade of working in industry. He has been a Reader in concrete structures since 2011. Dr Vollum's research interests are wide, encompassing the following topics: long-term deflections of reinforced concrete slabs, beam-column joints, shear in beams, punching shear, numerical modelling of reinforced concrete structures, strut and tie modelling, and control of early age thermal cracking.
He has developed a method for predicting the deflection of slabs that takes construction loading into account. The numerical work was calibrated with data from the in-situ concrete building at BRE Cardington with which he was closely involved. More recently, he led an EPSRC project (EP/D505488/1) which developed a design method for using concrete blinding as struts in cut and cover excavations.
Dr Vollum also represents Concrete Society on BSI Committee for EC2 B/525/2 Structural Use of Concrete. He is a member of the subgroup of B/525/2 which is responsible for developing and maintaining the UK National Annex to EC2. He is also the UK technical expert on TG4 of WG1/CEN/TC 250/SC 2. TG4 is the European committee which is considering revisions to shear, punching and torsion in the next version of EC2 which is due in 2020. He is also a member of fib Task Group 4.2 which evaluates and develops models for ultimate limit states of concrete structures.
