“…Fatigue simulation for composite deck under moving loads 3.1 Fatigue simulation: damaging process (1) Model profiles and procedure of moving load in analysis Using the interface element described above, the direct path-integral scheme, which was summarized in the previous section, is directly applied to the fatigue simulation of steel-concrete composite slabs under high cycle moving loads. The composite deck model investigated here faithfully follows the experimental study reported by Sakurai et al (2005) (see Fig. 10).…”

This paper investigates the failure mode and the damage mechanism of steel-concrete composite slabs under high cycle fatigue loads by using three-dimensional nonlinear finite element analysis. The applicability of the simulation system, which was originally developed for reinforced concrete slabs, is extended to the steel-concrete composites with the proposed interface element, and experimentally verified with fatigue loading tests for bridge decks. The computed midspan deflection of composite slabs shows a fair agreement with data obtained from the experiment, and the horizontally induced cracking observed in reality is properly reproduced by the computational simulation. Finally, the authors predict the ultimate state at which the upper concrete layer separated by horizontal cracks fails in compression fatigue, and the corresponding S-N diagram is computationally predicted for the future discussion.

Bridge Association, Engineering Committee, Subcommittee on Bridge Slab Engineering (Nishi-shinbashi 1-6-11, Minato-ku, Tokyo 105-0003, Japan) This paper shows the failure mechanism of steel-concrete composite bridge deck having studs and ribs subjected to repetitive moving loads. Three-dimensional nonlinear FE analysis was used. First, the property of interface element between steel and concrete was identified by sensitivity analyses. Next, the progress of strains of concrete and steel elements obtained in simulation were examined throughout all the loading programs of wheel running tests. In particular, special attention was devoted to the development of horizontal cracks inside the concrete. Furthermore, static analysis was performed to highlight the difference in the failure process given by the fixed point load and the one caused by the moving load. Considering a particular failure mechanism of the deck under moving load, setting a proper limit states and control level for engineering practice was strongly required.
