Dynamic Behaviour of Composite Floors

摘要

As part of an on-going experimental and analytical research effort to evaluate the fatigue strength of composite slabs, 18 Bond-lok composite slabs have been tested statically and dynamically in bending. Special interest has been paid to bond failure between the concrete and steel deck. The effect of both small and large amplitude loadings on fatigue strength and deformation characteristics has been examined. Based on the fatigue strength results, a guide for the design of composite slabs subjected to fatigue loading has been provided. The information is provided in the form of modified Goodman diagrams and algebraic expressions that can be utilised for design.
