ABSTRACT
ABSTRACT In this study, authors investigated a fatigue life prediction method for RC slabs considering effects of support condition and stepped incremental load based on experimental data of traveling wheel-type loading test. At first, to properly predict the fatigue life of RC slabs under constant cyclic loading test, a coefficient which represents influence of support condition was introduced to previous prediction method that authors had proposed. The modified method can cover three types of support conditions; simply support along longitudinal direction and elastic support along transverse direction, simple support along longitudinal direction and free ends along transverse direction, and simple support along all directions. Besides considering fatigue damage caused by preceding loading block as reduction of shear strength due to cyclic loading, a new evaluation method for stepped incremental loading test was proposed.
