Over the past 10 years, Extradosed bridges have become an attractive structural type around the world, due to the good results obtained with the first bridges constructed in Japan. This new typology, generally recognized as an intermediate solution between cable stayed bridges and cantilever constructed prestressed box-girder bridges, because these...

A large-scale, two-span bridge model constructed by assembling precast elements was tested under a series of bi-axial ground motions simulated on a shake table at the Earthquake Engineering Laboratory at the University of Nevada, Reno. The response of the bridge was estimated before the tests using a three-dimensional computational model developed...
Article
Shake-table studies were conducted on a large-scale, two-span accelerated bridge construction (ABC) bridge model that incorporated 38 precast concrete elements and six emulative ABC connection types. The studies were aimed to assess the seismic performance of the bridge model and the six ABC connections under biaxial horizontal ground motions simul...
Article
A prerequisite to the implementation of accelerated bridge construction (ABC) in moderate and high seismic regions is reliable data proving that bridges constructed by assembling precast elements can emulate the seismic performance of cast-in-place bridges. Previous seismic studies have not provided sufficient information about the interaction of c...
Article
The need for sustainable building materials has progressively increased the interest in the use of vegetable fibers as reinforcements in cementitious matrix composites. These fibers are renewable, inexpensive, and offer other advantages, such as lightness, stiffness, biodegradability, and high impact resistance. This review presents research conduc...

Intermediate diaphragms (ID) in bridges with precast girders are intended to improve load distribution among girders. Despite this, their efficacy has been doubted recently due to the complex construction tasks needed to join them to the girders. Accordingly, this work aimed to determine the effect of the number of IDs on the distribution of vertic...

Past studies have demonstrated that the vertical earthquake component can substantially affect the seismic performance of bridges and buildings. This component is typically ignored or, when included in the design, is estimated as two-thirds of the horizontal seismic design earthquake. This paper presents the characterization of the acceleration amp...

La construcción de los puentes viga cajón se ha incrementado en años recientes en Colombia. Algunos estudios previos para estos puentes han mostrado que la omisión en el análisis estructural del proceso constructivo, las propiedades reológicas de los materiales y las condiciones medioambientales pueden generar efectos significativos en los resultad...
Article
The rupture of a cable in cable-supported bridges is an accidental condition that should be considered during the design phase due the impact that this situation could have on the structural safety of the bridge and users. For that reason, design guidelines suggest carrying out a pseudo-static analysis where the failing cable is replaced by a load...
Conference Paper
Balanced cantilever box-girder bridges may be more seismically vulnerable during construction than after completion due to the higher flexibility and lower redundancy of the uncompleted structure. To estimate the seismic response of these bridges during construction, the Colombian bridge design Code defines a spectral linear-elastic, force-based ap...
Conference Paper
The Colombian bridge design code was updated in 2014 after almost 20 years of using the previous version published in 1995, referred to as CCP-95. Several updates were included in the current code (CCP-14), with the most important being the change in the design philosophy (from LRF to LRFD method) and the update of the live load and seismic hazard....

La aplicación del Reglamento Colombiano de Construcción Sismo Resistente implica que se defina la capacidad de disipación de energía (CDE) de la estructura en función de la tipología y la amenaza sísmica del sitio. En esta investigación se determinaron los efectos de elegir una CDE superior a la mínima permitida, en regiones de sismicidad intermedi...

Las propiedades mecánicas de los materiales pueden determinase a partir del estudio de sus respuestas frente a cargas externas. Estas permiten describir o predecir el comportamiento y resistencia de elementos que hacen parte de sistemas, por ello es de vital importancia determinarlas con el fin de emplear dichos materiales en los diferentes problem...
Conference Paper
Full-text available
La construcción acelerada de puentes (CAP) ha sido ampliamente utilizada en proyectos de infraestructura vial, en especial en los Estados Unidos. Este método resuelve los problemas asociados con los tiempos relativamente largos de la construcción convencional (vaciado en sitio), puesto que se emplean elementos o componentes prefabricados que son co...

Dentro de las metodologías de construcción más utilizadas para puentes de viga cajón sobresale el método de voladizos sucesivos. En este método, la superestructura es construida de manera progresiva y cuasisimétrica respecto de las pilas usando dovelas hormigonadas in-situ. El proceso se basa en carros de avance apoyados en dovelas predecesoras que...

This paper shows the importance of performing an asynchronous dynamic analysis for some bridge types. First, the existence and damage caused by the asynchronous seismic excitation are explored. Then, the general mathematic expression that describes the movement of structures under non-uniform seismic excitation in its supports and the asynchronous...

COMPARACIÓN DE LA RESPUESTA DE UN PUENTE EXTRADOSADO CON LUZ CENTRAL DE 200 m BAJO EXCITACIÓN SÍSMICA ASÍNCRONA Y EXCITACIÓN SÍSMICA UNIFORME
Conference Paper
Full-text available
The seisms travel through the soil with apparent wave velocity that is determined by the type of soil in which it is transmitted. The seismic wave attacks structural support with a time delay if a finite speed is considered, this phenomenon is known as asynchronous seismic excitation (asynchronous analysis). If the speed is assumed to be infinite,...

Since their appearance in 1994, extradosed bridges have played an important role in road and railway projects, competing (in medium span lengths) with cables-stayed and prestressed box girder bridges. At a regional level, extradosed bridges have been implemented more frequently in Asia, but recent projects developed in Europe and America show a gro...
