Continually increasing demands on infrastructures mean that maintenance and renewal require timely, appropriate action that maximizes benefits while minimizing cost. To be as well informed as possible, decision-makers must have an optimal understanding of an infrastructure’s condition—what it is now, and what it is expected to be in the future. Written by two highly respected engineers, the second volume, Infrastructure Health in Civil Engineering: Applications and Management, integrates the decision making concept into theoretical and practical issues. It covers: State-of-the-art practice and future directions Use of probability and statistics in areas including structural modeling Specific practical applications, including retrofitting and rehabilitation in response to earthquake damage, corrosion, fatigue, and bridge security Use of IHCE for management and maintenance of different types of structures using pre-stressed and reinforced concrete, and fiber-reinforced polymers (FRPs) Numerous practical case studies, as well as coverage of the latest techniques in the use of sensors for damage detection and load testing Built to correspond to the ideas presented in its companion volume, Theory and Components, this is an invaluable guide to optimized, cost-saving methods that will help readers meet safety specifications for new projects, as well as the aging infrastructure at great risk of failure.

TRB's Transit Cooperative Research Program (TCRP) Report 144: Sharing the Costs of Human Services Transportation, Volume 1: The Transportation Services Cost Sharing Toolkit and Volume 2: Research Report explore issues and potential solutions for identifying and sharing the cost of providing transportation services for access to community-based human services programs. Collectively, the two volumes examine current practices and offer strategies for collecting necessary data, addressing administrative and policy-related issues, and establishing cost allocation procedures. Volume 1: The Transportation Services Cost Sharing Toolkit leads the user through the process of setting up the necessary cost accounting system, identifying the data requirements and the measurement parameters, and describing procedures for applying the model. This volume concludes with instructions for using the actual Cost Sharing Model. Volume 2: The Research Report summarizes all of the study components that contributed to formation of the Toolkit. It includes an extended evaluation of current experience and describes the regulatory environment that frames transportation service delivery requirements. An executive summary of the report is included with the printed report. The report includes the Cost Sharing Model along with instructions for setup and application on a CD-ROM, which is packaged with the reports.

This report provides recommendations to revise the AASHTO LRFD Bridge Design Specifications relating to the distribution of live load to buried structures. The report details the development of simplified design equations (SDEs) for structural response based on three-dimensional (3D) analysis of 830 buried culverts. In addition, the report provides guidelines for conducting 2D and 3D modeling for design situations with conditions not covered by the SDEs. The material in this report will be of immediate interest to roadway and bridge designers.
