Damage due to earthquake is commonly related to substantial direct and indirect losses, highlighting the need for damage detection and retrofit prioritization based on the results of the seismic risk assessment of the road network. In this context, numerous methodologies have been developed for the seismic vulnerability assessment of bridges for different levels of seismic hazard using fragilit...

Bridge decks deteriorate over time as a result of freezing-and-thawing, heavy use, and water penetration resulting in internal defects. Ground penetrating radar (GPR) can be used as a non-destructive method for detecting such defects. Unfortunately, reflections from closely spaced objects overlap which prevents the accurate estimation of the round-trip travel time of GPR waves to the closely sp...

This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...

Seismic behavior and performance of the new Self- Anchored Suspension (SAS) Bridge San Francisco Bay System is studied using response data recorded during October 14, 2019, Mw4.6 Pleasant Hill earthquake. The bridge went into service within last decade as a replacement for older truss that spanned between Yerba Buena Island East Bay. During 19, 1989, M6.9 Loma Prieta earthquake, which occurred ...
