| 要旨 | This study analytically investigates the effect of damage on loads distribution behavior of curved RC deck slab using linear finite element analyses. The idealized damage consists of the degradation of concrete properties and the removal of spalled concrete in slab. The live-load distribution factors are clarified using the beam-line and load fraction methodologies and are compared to AASHTO design equations. Results indicated that the spalled concrete damage significantly affects the live-load distribution factors for girders, while the deteriorated concrete properties show no effect. |
