The RIME Group presented 4 papers in ACI Fall 2014 Convention in D.C.

Date: 10/26/2014

Dr. Hani Nassif has moderated 6 sessions with Dr. Nakin Suksawang at Florida Institute of Technology (nsuksawang@fit.edu) during (ACI 2014 Fall Convention.) in Washington D.C on October 26-30, 2014.

This two-day (6 sessions) Symposium on Structural Health Monitoring of Concrete Structures (Part 1a, b, c: Durability & Part 2a, b, c: Serviceability), which will be attended by international partners from Korea, Brazil, and China, is also co-sponsored by the ACI committees: 209-creep and shrinkage, 222-Corrosion, 342-Bridge Evaluation, Joint ACI-ASCE 343-Concrete Bridges, 435-Deflection, and 348-Structural Safety.

Brief description: Structural health monitoring (SHM) provides significant advantage in developing a comprehensive and realistic approach for the qualitative assessment and evaluation of concrete structures. The information obtained from monitoring can provide engineers, owners, contractors, and concrete suppliers to improve their maintenance activities, increase the safety, verify hypotheses, reduce uncertainty, and to widen the knowledge concerning the structure being monitored. The aims of this symposium are: (1) to pull together the knowledge on the assessment of concrete durability and serviceability using SHM technologies; and (2) to present new development in the SHM technologies, their performances, and their applications. Part Ia, b, and c will cover various aspect of concrete durability such as corrosion monitoring, service life prediction, and the monitoring of environmental degradation of concrete structures. Part 2a, b, and c will cover cracking, deflection, fatigue, and serviceability limits in codes. In both parts the prognosis using SHM will be emphasized. The symposium is organized as an holistic overview and includes all aspects of monitoring.

Desired outcome: Awareness will be raised on established SHM technologies for evaluating concrete durability and serviceability. Various SHM technologies such as traditional strain gauges and discrete fiber optic sensors, as well other emerging technologies such as distributed fiber optic sensors, sensing sheets, self-sensing materials, novel algorithms for data analysis, and novel methods for prognostication and decision making based on SHM will be presented. A symposium publication in the form of ACI SP as a compendium of reviewed papers will also be published.
