Introduction

Reinforced concrete slabs rigidly connected with steel girders have been used to form the basic superstructure of large numbers of deck bridges for many decades. This is due to the fact that the composite construction method offers the bridge engineers a great variety of solutions for different types of problems. A typical composite cross section of a highway bridge is shown in Fig. 1. A series of parallel steel girders are rigidly connected with a reinforced concrete slab through shear connectors. The shear connectors installed are mostly welded studs allowing use of the deck as part of the top flange ( deck plate girders). The longitudinal bending of the composite T-girders, at sagging bending areas, results in tension in steel and compression in concrete. The simultaneous operation of both of these materials generates the composite action which is the most important feature for the...
