Análise dinâmica de uma ponte com protensão no extradorso
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Civil, 2012-03-30)
Searching for more slender structures, economically viable and aesthetically appealing drove and innovation in the bridges. Prestressing, both internal and external, has been used on a large scale due to its efficiency; ...
Wooden bridges with deck of sawn board and round beams: main orientations
(2021-01-01)
The county of Itapeva–SP, Brazil, has a great territorial extension, with many vicinal roads and, consequently, many wooden bridges with some type of problem. This research had the purpose of analysing 34 wooden bridges, ...
E-bridge 3.0: A strategic approach to structural health monitoring of bridges in Costa Rica
(IFIP Advances in Information and Communication Technology, 2016)
The general condition of road infrastructure is a major weakness of the
Costa Rican economy. In particular, a significant percentage of national bridges show
an average or critical condition regarding parts of their ...
Structural Behavior of Barges in High-Energy Collisions against Bridge Piers
(American Society of Civil Engineers, 2016-02)
The collision of barges against bridge piers is an extreme loading condition that usually governs the design of bridges that span navigable waterways. The magnitude and time variation of impact forces depend on several ...
Life-Cycle Cost of Bridges on Seismic Zones for Risk Management
(Instituto Politécnico Nacional, 2016)
Ductile Concrete End-Diaphragms of Slab-on-Girder Concrete Bridges
(2022-01)
In this paper, the results of the proposed ductile precast concrete end-diaphragm beams for the transverse seismic resistance and protection of the substructure of slab-on-girder concrete bridges, tested at the facilities ...
Proposal of an Integrated Index for Prioritization of Bridge Maintenance
(ASCE-AMER SOC CIVIL ENGINEERS, 2010)
The bridge rating used in bridge management systems commonly uses only a structural condition. Factors such as seismic risk, hydraulic vulnerability, and strategic importance are commonly used in an isolated fashion. ...
Effects of Bridges construction on the benthic invertebrates structure of the Delta Paraná River
(Interciencia, 2005-02)
Benthic assessment of lotic environments impacted by bridge and highway construction at the Paraná River Delta is reported. The purpose of the study was to examine the degree of impact of physical disturbances on benthic ...
Molecular modeling of low bandgap diblock co-oligomers with π-bridges for applications in photovoltaics
(2018-09-01)
Recently, the diblock co-oligomers concept, a new design method to obtain conjugated organic compounds for varied applications in photovoltaics was proposed. These materials combines the interesting properties of extended ...
