EMI Session #2: Objective Resilience Part 2

Session Moderator: Mohammed Ettouney, Ph.D., P.E., Dist.M.ASCE

Presentation #1: Speaker - John Campbell, PhD, PE; 
National Ready Mixed Concrete Association

Abstract:

Resilience is the ability to resist and recover from adverse events, and concrete is ideally suited to producing resilient structures. With proper selection of materials and attention to detailing, concrete facilities can be designed to resist all hazards, such as seismic, blast, flood, fire, and high wind, and achieve practically any level of desired performance. Basic information is presented in this chapter for improving the resilience of concrete structures, and references are provided to direct the user to more detailed guidance. In addition, a discussion of the meaning of resilience, the aspects that must be considered, the relationship between sustainability and resilience, and one possible quantifiable measure of resilience are presented. Moving beyond hazard design, the use of concrete to meet resilience objectives in terms of adaptation and repair is discussed. Finally, a summary of recent developments in the concrete industry and best practices is presented.

Learning Objective(s):

  • Understand the definition of resilience in the context of building and infrastructure design.
  • Identify the ways in which concrete construction adds to resilience.
  • Obtain knowledge on recent advances in concrete technology that enhance resilience.

 

Presentation #2: Sustainable and Resilient Structural Engineering, Mechanics, and Materials (SR‐SEMM)

Sustainability and resilience of the built environment are major concerns in infrastructure planning and development. Climate change and depletion of natural resources have shifted the engineering paradigm toward environmental resilience, social equity, and techno‐economic sufficiency of infrastructure development. However, the long history of neglecting built infrastructure and exploiting the natural environment have created major challenges for engineers to prioritize social and environmental justice while balancing capital, operation and maintenance expenditures. Engineering professional entities have developed guidelines, specifications, and codes to facilitate decision making processes and measuring the effectiveness of innovative engineering solutions for overcoming such challenges. However, implementation and deployment of such solutions in the built environment are above and beyond conceptual frameworks as they require application of innovative materials and techniques in design and construction of structures supporting engineering systems. The field of sustainable and resilient structural engineering, mechanics, and materials (SR‐SEMM) incorporate cross‐disciplinary concerns with natural resources, as well as objective approaches to mitigate climate‐related disasters. This presentation introduces fundamental motivations, key concepts, and a brief review of selected applications of SR‐SEMM, from lightweight materials to seismic isolation systems for sustainable and resilient infrastructure. Discussions include technical, environmental and societal performance of applications using common practices and guidelines for assessing safety, sustainability, and resilience in a wide range of civil engineering domains such as buildings, roadways, embankments and marine environments. Outcomes provide a roadmap for professionals in planning, management, design, and construction to adopt SR‐SEMM solutions in practice.

Learning Objectives:

  • Identify and explain three principles of sustainability and resilience and apply them to selected SR‐SEMM solutions in civil engineering projects following ISI Envision Framework and UN SDGs.
  • Analyze five domains of sustainable and four domains of resilient performances for selected SR‐ SEMM solutions in complex civil engineering projects following ISI Envision and EMI ORC MOP.
  • Comprehend, analyze, develop, and assess PCR, EPD, and LCA documents for selected SR‐SEMM practices across three Net Zero concepts following EPA’s Initiative and ASCE COS Standard.
