Corrosion of reinforcement is a major problem affecting a large number of reinforced concrete structures. At present, most reliability-based design studies of reinforced concrete structures do not consider the effects of corrosion. In this paper, we present a reliability-based approach to the design of reinforced concrete bridge girders that are under corrosion attack. Both reserve and residual...

This paper proposes the use of neural network(NN-) based pavement structural analysis tools as surrogates for the flexible pavement response analysis in the new mechanistic empirical pavement design guide (MEPDG) developed for the American State Highway and Transportation Officials (AASHTO). Some of the recent successful applications of NN-based structural analysis models for predicting critica...

Transportation agencies’ motor vehicle count programs tend to be well established and robust with clear guidelines to collect short-term count data, to analyze data, develop annual average daily traffic (AADT) adjustment factors, and to estimate AADT volumes. In contrast, bicycle and pedestrian traffic monitoring is an area of work for most transportation agencies. In most agencies, there are a...

Simplified code provisions can be used for the analysis and design of straight slab bridges. However, several studies question appropriateness simplified procedures skewed geometries. This paper provides practical insights to designer regarding effects skewness in reinforced concrete bridges by evaluating how more refined impact magnitudes resulting reinforcement layouts. The methods this study...

Belitic calcium sulfoaluminate (BCSA) cement is a sustainable alternative to Portland that offers rapid setting characteristics could accelerate throughput in precast concrete operations. BCSA cements have lower carbon footprint, embodied energy, and natural resource consumption than cement. However, these benefits are not often utilized structural members due lack of specifications perceived l...

En la actualidad existen diferentes opciones para incrementar resistencia última de vigas esbeltas sujetas a cargas concentradas. Algunas estas alternativas incluyen el uso rigidizadores transversales cercanamente espaciados y utilización longitudinales. Sin embargo, estudios recientes han demostrado que también mejora mediante tipo delta, los cuales consisten en dos láminas soldadas entre alma...
