Evaluation of Behavior of Hybrid Beam Combining Steel Inverted T-Section and RC Flange

This paper deals with flexural investigation of a type of steel-concrete composite beam structure able to provide an adequate bond between steel and concrete elements through the application of a simple steel reinforcement shear connector design, steel reinforcing bars bent into L-shapes. The cross sections involve inverted steel T-beam being embedded within reinforced concrete (RC) flange of the slab. The paper concentrates on elastic and elastic-plastic behaviour of steel inverted T-beam entrenched within a reinforced concrete flange at the top. In addition, shear connection was investigated in detail. Finally, some suggested designing equations and curves simulating the elastic, elastoplastic and full plastic experimental moments were developed. The plastic theoretical study results coincides with the experimental behaviour of the developed model.

Obok inicjacji korozji zbrojenia chlorki degradują również matrycę cementową. W artykule uwagę skupiono na procesie i warunkach wiązania. Jest to ważne, bo jony Cl, związane z matrycą cementową, mogą stanowić rezerwuar jonów wolnych przy powierzchni rozdziału stal-beton.

By the steel corrosion initiation, chlorides degrade also cement matrix. The attention is focused on binding process and binding conditions in this work. It is important, because Cl bound with cement matrix can present the reservoir of ?l ions free by concrete-steel interfacial transition zone.
