Billions of dollars are spent each year in the United States addressing damage to concrete structures caused by corrosion of embedded reinforcing steel. Costs to address damage from corrosion can increase exponentially as damage becomes prevalent and considerable life-cycle cost savings can be achieved through preventative maintenance and proactive mitigation of ongoing corrosion prior to the onset of extensive damage. A variety of techniques are available for protecting structures from deleterious exposures and impeding corrosion once initiated. These sessions will present some of the newer trends and technologies for protecting concrete and mitigating on-going corrosion.

Bridge infrastructure serves as the backbone of the transportation industry, playing an often-overlooked role in the economy until service is disrupted. The sophistication of seismic design practices continues to improve and holds an expanding stake in maximizing service life of bridges in the research and engineering community alike. Multi-shock ground motion effects such as Mainshock-Aftershock earthquake sequences present another design challenge, as aftershocks typically occur within a time period where repairs to the initial damage incurred during the mainshock are not able to be realized. Most of the recent major earthquakes around the world were followed by aftershock events, and showed that structures’ vulnerability to higher levels of damage envisaged during design increases under multiple ground motion effects. Thus, a structure designed for minimal or moderate level damage could undergo severe damage or even collapse under multi-shock sequences.Observations from recent earthquakes have shown that, when subjected to aftershocks, structures can experience greater damage as a result of significant reduction of stiffness and strength in structural components from mainshocks. Development and implementation of innovative analysis and assessment methods, design of bridges considering the MS-AS sequence are expected to improve the bridge seismic resilience and minimize traffic interruption.
Learning Objectives:
(1) Present recent findings regarding the behavior of bridge component and systems under sequential ground motions;
(2) Discuss the new experimental and numerical approaches for bridge analysis and design considering MS-AS ground motions;
(3) Identify suitable ground motion selection techniques, proper intensity measures and demand parameters selection for bridge performance evaluation considering MS-AS sequences;
(4) Summarize new design approaches, performance requirements, and fragility analysis of bridges considering MS-AS ground motions.

Title: Fiber Reinforced Composites – Designer Materials for the Future of Infrastructure
Fiber reinforced composites provide the civil engineer with a palette of options not available with traditional materials due to their light weight, high specific performance attributes, local and global tailorability, ease of placement in the field and relatively high durability. They can be used in applications ranging from the rehabilitation of deteriorating and understrength steel and structural concrete components to the development of new structural systems that can be multifunctional and can integrate form and function far easier than traditional structures. Their tailorability enables the designer to effectively optimize materials and structural systems and could enable the rapid deployment of large scale intelligent structural systems in the future.
All are welcome to register for the lunch. Following the lecture, the results of the student competition will be announced. For additional information on the Student Lunch, please visit www.aciconvention.org.

1:30 PM - 3:30 PM

Moderator: Shahria Alam

The evolution of the seismic design provisions in response to the lessons learned from previous earthquake events has led to the development of new design methodologies such as performance-based design (PBD). A key component of PBD is to lay out the engineering demand parameters identifying the initiation of different damage states (e.g., yielding, spalling, bar fracture, etc.). In this regard, reliable knowledge of structural members’ strength and deformation capacities is required, and it is often obtained through quasi-static cyclic testing programs. The selecting of an appropriate loading protocol is crucial in these programs to achieve.
Learning Objectives:
(1) Existing research and standards on deformation limits and acceptance criteria for different performance levels of reinforced concrete elements and connections;
(2) Performance of different structural components tested under different types of quasi-static cyclic loading;

Structural health monitoring (SHM) and nondestructive testing (NDT) are frequently employed to assess or track the condition of concrete structures. While SHM and NDT are frequently discussed in the same context, and the terms have even been used interchangeably, they refer to different techniques and have their own distinct objectives. However, confusion persists within the industry about what constitutes NDT and what constitutes SHM; in some instances, certain techniques are categorized as both SHM and NDT. Additionally, terms like nondestructive evaluation (NDE), nondestructive inspection (NDI), and structural monitoring, among others, are also used. ACI Committees 228 (Nondestructive Testing of Concrete) and 444 (Structural Health Monitoring) are working to formalize the distinction between SHM and NDT and define terms used in these fields. Ultimately, this will lead to a better understanding and increased adoption of SHM and NDT within the concrete industry.
The primary goal of this forum is to alleviate confusion within the industry about the distinction between SHM and NDT. The forum will define SHM and NDT, explain the relationship between them, and give examples of how they are applied within the concrete industry. The forum will introduce the development of SHM and NDT, discuss the current state of the art, their inter-relations, and provide a vision for future directions in both areas.
Learning Objectives:
(1) Define and give examples of structural health monitoring (SHM);
(2) Define and give examples of nondestructive testing (NDT);
(3) Explain the relationship between SHM and NDT;
(4) Summarize the state of practice of SHM and NDT within the concrete industry.
