Abstract: This paper demonstrates the analysis of the deterioration trends of the various types of bridge structural design and/or construction in the entire U.S. National Bridge Inventory, to derive and compare operational structural ...

Abstract: This paper analyzes the raw database of the entire bridge inventory in the United States and derives distinctive bridge type-specific structural performances. The distributions, 15-year histories, and average ages of bridges ...

Abstract: The diagnostic concept of the structural deficiency of bridges is an essential engineering and management consideration with implications of performance. The structural deficiency analysis reflects the constructed system ...

Abstract: This paper evaluates the operational structural performances of the various kinds of bridge construction materials and/or structural designs, considering the deck areas of bridges, rather than their discrete counts. Deck ...

Abstract: Tech 21 is the third all-composite vehicular bridge installed in the United States. The deck has sandwich configuration with a center core made by bonding orthotropic fiberglass and polyester tubes. The three trapezoidal ...

Abstract: Experimental field load-test and finite-element analysis were carried out for the performance assessment of a precast-concrete, modular, three-sided, low-profile, buried, arch bridge system. Finite-element analysis ...

Abstract: Precast-concrete, skewed bridges with integral abutment walls are, typically, designed as simplified plane rigid portal frames, neglecting the degrading effects of the skew angle, the influence of haunches between the ...

Abstract: Results of laboratory tests on four reinforced concrete flat slab‐interior column connections, carrying quasi‐static, cyclic, horizontal loadings are presented. The specimens, at about two‐thirds scale, had reinforcing ...
