This Week's Featured Presentation

Overview of ACI 301
by Michelle L. Wilson, Portland Cement Association

Session details

Construction Documents Using ACI 301 to Comply with ACI 318 Chapter 26 (ACI Fall 2016 Convention, Philadelphia, PA)
This session addresses how to use ACI 301, “Specifications for Structural Concrete,” to comply with ACI 318, Chapter 26, “Construction Documents.”

Upcoming Presentations

October 23 – 29

Effect of Fly Ash and Silica Fume on Time to Corrosion Initiation for Specimens Exposed Long-Term to Seawater
by Francisco Presuel-Moreno, Florida Atlantic University

Session details

Chloride Limits and Thresholds for Concrete Containing Supplementary Cementitious Materials (SCMs) (ACI Fall 2016 Convention, Philadelphia, PA)
ACI uses cement content alone as the basis for allowable chloride limits for new construction. With the heightened use of SCMs and performance specifications for cement, there is need to evaluate using total cementitious materials content as the basis for allowable chloride limits in new construction and for chloride thresholds. These allowable and critical chloride values, along with other important factors, can significantly impact the service life of reinforced concrete structures. The purpose of these sessions is to inform the audience of recent research in these areas so that recommendations on the allowable and critical chloride values can be evaluated and validated. This session will be useful for researchers, engineers, consultants, and those developing standards and specifications.

October 30 – November 5

Risk Acceptance Criteria in Safety Evaluation and Design of Existing Concrete Structures
by Ming Liu, Naval Facilities Engineering Command

Session details

Evaluation of Concrete Structures (ACI Fall 2016 Convention, Philadelphia, PA)
The structural evaluation process of existing concrete structures involves the understanding of existing capacity, safety, and future expected life. Although there are some codes and guidelines to help engineers to obtain this information, the acceptable criterion is the target reliability index, which is rarely used or defined in current codes. The objective of the proposed session is to present the challenges and solutions using more rational reliability approaches in evaluating concrete structures. Papers on evaluation methods, prediction models, reliability analysis, and code calibration will be presented.
