Available in PDF, EPUB and Kindle. Book excerpt: Due to significant economic growth in the last few decades, increasing traffic loads impose tremendous demand on bridge structures. This, coupled with ongoing deterioration of bridges, introduces a unique challenge to bridge engineers in maintaining service of these infrastructure assets without disruption to vital economic and social activities. This requires innovative solutions and optimized methodologies to achieve safe and efficient operation of bridge structures. Bridge engineering practitioners, researchers, owners, and contractors from all over the world presented on modern techniques in design, inspection, monitoring and rehabilitation of bridge structures, at the Sixth New York City Bridge Conference held New York City on July 25-26, 2011. This book contains a select number of papers presented at the conference. This group of papers provides a state-of-the-art in bridge engineering and is of interest to any reader in the field.

Book Synopsis Seismic Assessment, Behavior and Retrofit of Heritage Buildings and Monuments by : Ioannis N. Psycharis
Download or read book Seismic Assessment, Behavior and Retrofit of Heritage Buildings and Monuments written by Ioannis N. Psycharis and published by Springer. This book was released on 2015-05-05 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assembles, identifies and highlights the most recent developments in Rehabilitation and retrofitting of historical and heritage structures. This is an issue of paramount importance in countries with great built cultural heritage that also suffer from high seismicity, such as the countries of the eastern Mediterranean basin. Heritage structures range from traditional residential constructions to monumental structures, ancient temples, towers, castles, etc. It is generally recognized that these structures present particular difficulties in seismic response calculation through computer simulation due to the complexity of the structural system which is, generally, inhomogeneous, with several contact problems, gaps/joints, nonlinearities and brittleness in material constituents. This book contains selected papers from the ECCOMAS Thematic Conferences on Computational Methods in Structural Dynamics & Earthquake Engineering (COMPDYN) that were held in Corfu, Greece in 2011 and Kos, Greece in 2013. The Conferences brought together the scientific communities of Computational Mechanics, Structural Dynamics and Earthquake Engineering in an effort to facilitate the exchange of ideas in topics of mutual interest and to serve as a platform for establishing links between research groups with complementary activities.

Book Synopsis A Pre-tensioned Bent System for Accelerated Bridge Construction in Seismic Regions by : Ólafur Sveinn Haraldsson
Download or read book A Pre-tensioned Bent System for Accelerated Bridge Construction in Seismic Regions written by Ólafur Sveinn Haraldsson and published by . This book was released on 2015 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all bridge bents (intermediate supports) are constructed of cast-in-place reinforced concrete. Such bridges have served the nation well in the past, but to meet current design expectations, they need to be improved in three areas: 1) speed of construction, 2) seismic resiliency, and 3) durability. Building on previous research at the University of Washington (Hieber et al. 2005, Wacker et al. 2005, Pang et al. 2010, and Haraldsson et al. 2013), a new pre-tensioned bent system has been developed to address these needs. The system consists of 1) precast technology that reduces construction time, 2) unbonded pre-tensioning that minimizes post-earthquake displacements, and 3) high-performance materials that extend the bridge's life-span. Davis et al. (2012) tested a version of the system using conventional concrete in the plastic hinge regions. They found that pre-tensioning improved the system's re-centering capabilities but led to earlier bar buckling and bar fracture than in previously tested RC columns. In order to delay bar buckling and bar fracture, the system was modified to include Hybrid Fiber Reinforced Concrete (HyFRC) in the plastic hinge regions. This composite concrete has been shown to exhibit superior durability and cracking resistance (Ostertag et al. 2007). The effect of the HyFRC on the pre-tensioned bent system was investigated both with quasi-static and dynamic tests. The quasi-static tests showed that using HyFRC in the plastic hinge region increased column ductility; in all cases the column maintained more than 80% of its strength up to a drift ratio of 10%. The HyFRC also delayed spalling of the concrete, but it did not significantly increase the drift ratios at the onset of bar buckling and bar fracture. The shake-table tests of a cantilever column, which was designed to re-center up to a drift ratio of 3.0%, showed that the new system had lower expected residual drifts than columns constructed with conventional cast-in place methods. The pre-tensioned column had a residual drift of 0.23% after experiencing a peak drift ratio of 5.5%. In contrast, the companion reference column, constructed using cast-in-place technology, had a residual drift ratio of 0.83% after experiencing a peak drift ratio of 5.7%. A numerical model in OpenSees was developed and calibrated with a set of 34 RC quasi-static, cyclic tests. This model was calibrated using a concrete constitutive model that takes into account concrete early reloading, developed as part of this research, and used commonly used steel constitutive models; Giuffre-Menegotto-Pinto's (Steel02) model, and Moehle and Kunnath's (ReinforcingSteel) model. The simulations showed improved accuracy in comparison to previous research (e.g., Berry and Eberhard 2007), and showed that the response of the system was affected more by the chosen steel model than by the concrete model. The results of these simulations were used to make predictions of the response of five columns tested on the UC Berkeley shake table. These simulations showed that models built using the proposed strategy predict peak displacements quite accurately, especially at the yield and design level, but do not accurately capture residual displacements.
