Analysis of Dynamical Behaviors of Steel Deck-Concrete Composite Beams

摘要

The steel deck-concrete composite beam was mainly made of the three constitutes of steel deck, concrete and shearing conjunction, still with little amount of structure reinforcing bars moreover,In this paper the advantage of the steel deck-concrete composite beam was introduced. The hysteretic curve was provided also. The curve of the deck-concrete composite beam under the cyclic loads was more full and tactful. It explained the form of the joint had a better dynamical behaviors than the concrete beam;The energy-consumption ratio and the ductility coefficient of the deck-concrete beam was bigger. It reflected that the joint had better aseismic performances than the concrete beam.These conclusions had great importance for the design of engineering in the areas of earthquakes.
