Description

The evaluation of new and existing concrete structures relies on structural reliability and safety assessment and analysis approaches to understand their existing capacity, safety, and future expected life. ASCE/SEI 7 provides basic guidelines to help engineers to obtain this information with a well-defined target reliability index for new structures. However, the process for existing structures evaluation is undefined. The objective of the proposed session is to present the challenges and remedies engineers have in evaluating concrete structures that can be easily understood by the practitioner. Presentation on evaluation methods, prediction models, reliability analysis, reliability index and code calibration will be presented. Engineers and Researchers should attend.

Learning Objectives

• Discuss a reliability-based assessment to develop serviceability limit states as it applies to concrete bridge infrastructure.

• Explain reliability of modeling dead, live, wind, snow, and flood loading and load combinations referencing ASCE/SEI 7 in terms of safety margins used in design of concrete structures and assessment of existing concrete structures.

• Describe a sound statistical approach to obtain representative sampling and evaluation methods of existing concrete structures with different confidence levels.

• Discuss structural reliability basics and their application on analyzing structural performance, such as load and resistance factors used in structural analysis based on uncertainties of load components and uncertainties, resistance capacity to minimize target reliability index, or acceptable minimum safety margin.
