Book Description
An experimental and theoretical study was conducted to define and explain the general inelastic deformational behaviour of reinforced concrete voided slabs under symmetrical and unsymmetrical cases of loading up to failure. In the experimental phase of this work, six voided reinforced concrete slabs were tested. The varying parameters for these tested slabs were the void-depth ratio and the percentage of the longitudinal and the transverse reinforcement. In the theoretical phase of the study, a nonlinear finite element analysis was conducted for reinforced concrete voided slabs. In this analysis, a layered rectangular element was developed in order to account for the varied material properties within an element. Each layer may have different properties, corresponding to its state of stress or strain, its material, or its geometry. The theoretical phase of this study, was also undertaken to test the validity of orthotropic plate theory in analyzing voided reinforced concrete slabs, especially after cracking of concrete. The results of this experimental-theoretical study were combined with other available information to formulate some recommendations concerning the design, construction, analysis and economy of this type of bridge. For the covering abstract of the Conference see IRRD Abstract No. 807839.

Book Description
Bridge Maintenance, Safety, Management, Life-Cycle Sustainability and Innovations contains lectures and papers presented at the Tenth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2020), held in Sapporo, Hokkaido, Japan, April 11–15, 2021. This volume consists of a book of extended abstracts and a USB card containing the full papers of 571 contributions presented at IABMAS 2020, including the T.Y. Lin Lecture, 9 Keynote Lectures, and 561 technical papers from 40 countries. The contributions presented at IABMAS 2020 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of maintenance, safety, management, life-cycle sustainability and technological innovations of bridges. Major topics include: advanced bridge design, construction and maintenance approaches, safety, reliability and risk evaluation, life-cycle management, life-cycle sustainability, standardization, analytical models, bridge management systems, service life prediction, maintenance and management strategies, structural health monitoring, non-destructive testing and field testing, safety, resilience, robustness and redundancy, durability enhancement, repair and rehabilitation, fatigue and corrosion, extreme loads, and application of information and computer technology and artificial intelligence for bridges, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of making more rational decisions on maintenance, safety, management, life-cycle sustainability and technological innovations of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including engineers, researchers, academics and students from all areas of bridge engineering.

Book Description
This work provides a detailed and up-to-the-minute survey of the various stability problems that can affect suspension bridges. In order to deduce some experimental data and rules on the behavior of suspension bridges, a number of historical events are first described, in the course of which several questions concerning their stability naturally arise. The book then surveys conventional mathematical models for suspension bridges and suggests new nonlinear alternatives, which can potentially supply answers to some stability questions. New explanations are also provided, based on the nonlinear structural behavior of bridges. All the models and responses presented in the book employ the theory of differential equations and dynamical systems in the broader sense, demonstrating that methods from nonlinear analysis can allow us to determine the thresholds of instability.
