Abstract

Stud shear connectors in composite steel and concrete construction under impact J.M. Louw, A. van Dyk, A.K. Roux Institute of Structural Engineering, University of Stellenbosch, 7600, Stellenbosch, South Africa ABSTRACT The first results are reported of impact tests on stud shear connectors in composite steel and concrete construction with and without steel decks. The dynamic factor defined as the ratio of dynamic to static shear strength is compared at various stress rates to the factors for concrete and steel under axial stress computed as recommended by the CEB At high stress rates this factor exceeds that for axial stress in steel and in concrete. At these rates at least, the concrete apparently does not contribute to the dynamic strength. INTRODUCTION Control rooms in chemical plants are often framed in composite steel and concrete construction and required to be able to withstand a possible accidental exterior explosive force of a certain magnitude.
