Download or read book Bridge Traffic Loading written by Eugene OBrien and published by CRC Press. This book was released on 2021-12-03 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field – short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.

Download or read book A Contribution to Moving Force Identification in Bridge Dynamics written by Andrei Firus and published by Springer Nature. This book was released on 2023-03-17 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knowledge of the real forces acting on a structure are of great importance in the condition assessment process of existing structures. In this sense, this work provides a novel approach for identification of dynamic moving forces acting on a bridge structure. It seeks to find the optimal time dependent force values that minimize the difference between the computed and measured displacement and acceleration time histories for a limited number of sensor locations. The work also presents extensive experimental investigations of the developed method on real structures in operation, which consistently show that it can be successfully used on a wide range of applications: from small structures excited by rather low pedestrian forces up to the "heavy category" of a complete train passing a railway bridge. In this context, a set of particularities and limitations arising in the practical application of the method on real structures are also discussed.

Download or read book Sensing Issues in Civil Structural Health Monitoring written by Farhad Ansari and published by Springer Science & Business Media. This book was released on 2005-07-14 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Civil infrastructure systems are generally the most expensive assets in any country, and these systems are deteriorating at an alarming rate. In addition, these systems have a long service life in comparison to most other commercial products. As well, the introduction of intelligent materials and innovative design approaches in these systems is painfully slow due to heavy relianceon traditional construction and maintenance practices, and the conservative nature of design codes. Feedback on the "state of the health" of constructed systems is practically nonexistent. In the quest for lighter, stronger and corrosion-resistant structures, the replacement of ferrous materials by high-strength fibrous ones is being actively pursued in several countries around the world, both with respect to the design of new structures as well as for the rehabilitation and strengthening of existing ones. In North America, active research in the design of new highway bridges is focused on a number of specialty areas, including the replacement of steel reinforcing bars in concrete deck slabs by randomly distributed low-modulus fibers, and the replacement of steel prestressing cables for concrete components by tendons comprising super-strong fibers. Research is also being conducted on using FRPs to repair and strengthen existing structures.

Download or read book Extracellular Matrix in Development written by Douglas W. DeSimone and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells in the developing embryo depend on signals from the extracellular environment to help guide their differentiation. An important mediator in this process is the extracellular matrix – secreted macromolecules that interact to form large protein networks outside the cell. During development, the extracellular matrix serves to separate adjacent cell groups, participates in establishing morphogenic gradients, and, through its ability to interact directly will cell-surface receptors, provides developmental clocks and positional information. This volume discusses how the extracellular matrix influences fundamental developmental processes and how model systems can be used to elucidate ECM function. The topics addressed range from how ECM influences early development as well as repair processes in the adult that recapitulate developmental pathways.

Book excerpt: This document updates and expands the American Association of State Highway and Transportation Officials (AASHTO) User Benefit Analysis for Highways, also known as the Red Book. This AASHTO publication helps state and local transportation planning authorities evaluate the economic benefits of highway improvements. This update incorporates improvements in user-benefit calculation methods and, for the first time, provides guidance for evaluating important non-user impacts of highways. Previous editions of the Red Book provided guidance regarding user benefit measurement only. This update provides a framework for project evaluations that accurately account for both user and non-user benefits. The manual and accompanying CD-ROM provide a valuable resource for people who analyze the benefits and costs of highway projects.

Download or read book Major Powers and the Korean Peninsula written by Titli Basu and published by K W Publishers Pvt Limited. This book was released on 2019 with total page 3741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Korean Peninsula, which constitutes one of the strategic pivots of Northeast Asian security, has remained a contested theatre for major powers. Denuclearisation of the Peninsula is unfolding as one of the most defining challenges in shaping regional security. The end state in the Peninsula and how it is to be realised is debated amongst the stakeholders. This book aims to situate some of the critical issues in the Korean theatre within the competing geopolitical interests, strategic choices and policy debates among the major powers. This volume is an endeavour to bring together leading Indian experts including former Indian ambassadors to the Republic of Korea, senior members from the defence and strategic community to analyse the developing situation in the Korean Peninsula. The Korean Peninsula has remained a contested theatre for the major powers. Brutal wars have been fought involving imperial Japan, Czarist Russia, the Union of the Soviet Socialist Republics (USSR), Qing China, the People's Republic of China, and the United States (US) which left the Peninsula conquered, colonised, and divided, starting with Chosun (Yi) Korea from 1392-1910 to colonial Korea from 1910-45 to divided Korea since 1945.1 Subsequently, the Korean War from 1950-53 defined the character of the Cold War in Northeast Asia. The strategic choices in the Korean theatre have been influenced by the competing geopolitical interests of regional stakeholders. In the post-Cold War era, the Peninsula remained a key variable in shaping the Northeast Asian security architecture since the Democratic People's Republic of Korea or North Korea continued to employ the strategic use of nuclear brinksmanship.
