RISUltimate Analysis of Monolithic and Segmental Externally Prestressed Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: A numerical model for the ultimate analysis of externally prestressed concrete bridges has been developed. The proposed model can analyze simply supported or continuous, monolithic or segmental bridges, with external ...
Tradition and Innovation in Teaching Structural Design in Civil Engineering
Publisher: American Society of Civil Engineers
Abstract: This paper briefly reviews the history of structural engineering education: The dawn, development, and consolidation of traditional education systems, as well as their fall into decline in the contemporary technological ...
Improving the Wind Stability of Suspension Bridges during Construction
Publisher: American Society of Civil Engineers
Abstract: The wind stability of suspension bridges in the construction phase can often be more problematic than in the final state. In this paper, numerical wind stability analyses are performed for the erection process of both ...
Structural Damage Identification from Dynamic‐Test Data
Publisher: American Society of Civil Engineers
Abstract: The paper deals with a methodology for the use of dynamic response as an inspection and surveillance tool for concrete structures (mainly bridges). The method is based upon a finite‐element analysis for identification of ...
Closure to “Structural Damage Identification from Dynamic‐Test Data” by Juan R. Casas and Angel C. Aparicio

Improving Suspension Bridge Wind Stability with Aerodynamic Appendages
Publisher: American Society of Civil Engineers
Abstract: The influence of aerodynamic appendages on the wind stability of box-girder suspension bridges is examined, with special reference to the stability of bridges with very long spans (above 2,000 m). Aerodynamic appendages ...
Preliminary Design of Prestressed Concrete Stress Ribbon Bridge
Publisher: American Society of Civil Engineers
Abstract: A stress ribbon bridge is a very slender structure in which the deck hangs in a suspended cablelike form. The structural response of this kind of structure is complex because of the combined effects of geometric nonlinearity, ...
Externally Prestressed High Strength Concrete Viaduct
Publisher: American Society of Civil Engineers
Abstract: This paper presents an externally prestressed high strength concrete viaduct designed and erected in Spain. This viaduct, a three-span (41 + 50 + 41 m) continuous beam, has been designed and built with a 60-MPa strength ...
Structural Behavior of Inferior-Deck Spatial Arch Bridges with Imposed Curvature
Publisher: American Society of Civil Engineers
Abstract: Spatial arch bridges have significant out-of-plane behavior that must be controlled even under vertical loads. In some designs, the centerline of the arch may not lie within a plane. This study focuses on the structural ...
Biomimetic Treatments on Dental Implants for Immediate Loading Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Commercially pure titanium (cp Ti) dental implants have been widely and successfully used with high rates of clinical success in normal situations. However, there is still a lack of reliable ...
