“…One of the authors has thus far conducted a numerical analysis-based study using nonlinear finite element analysis (code: COM3D) based on the elasto-plasticity/failure constitutive laws of concrete together with a smeared crack model, in order to clarify the failure mechanisms of composite slabs that have relatively 'rigid' shear connectors 7), 8), 9) . These studies accurately reproduced the shapes of steel members using the solid elements and the initial bond and friction at the interface element between the bottom steel plate/shaped steel and the concrete material.…”

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.

As bridge deck slabs experience the direct impact of repeated concentrated wheel loads, they are more susceptible to fatigue‐related damage than other bridge components. In this context, a fatigue life prediction method for reinforced concrete (RC) bridge decks has been developed based on failure mechanisms of RC slabs tested under moving wheel loads. Initially, the formulas encompassed shear strength and S–N equations, accommodating variations in environmental and support conditions, are proposed to facilitate the fatigue life prediction of slabs exposed to constant moving wheel load. Subsequently, a model for shear strength degradation formulated using experimental findings on beam‐like elements is utilized in predicting the fatigue life of slabs subjected to stepwise moving wheel loads. The validity of the proposed method was established by comparing its results with previous experimental data. Notably, compared with the existing prediction equation, the proposed method exhibited more accurate fatigue life prediction results.
