These realistic assessments become the performance goals and they are next compared to the capability of the existing built environment when subjected to the expected major hazard events. The gaps between the goals and the existing conditions represent barriers to recovery.

Emerging structural engineering technologies can advance community resilience planning before and after hazard events occur. Before hazard events occur, design professionals play a leading role in the process of defining the hazards, developing appropriate design standards, determining the existing vulnerabilities within the built environment, and identifying cost-effective community wide mitigation opportunities.

It will target health related improvements to the community that will also provide economic benefit to local residents and business. It will track health data for the community in order to measure baseline health conditions, target pockets of disparity, and measure the improvement of health factors over time.

Degradation and failure are often attributed to material sources related to fatigue, damage, chemical or biological interactions, and environmental factors. Advanced technologies to develop resilient infrastructure include structural sensing and innovations in construction materials.

During a case study with a natural volcanic ash, we found that a more resilient material can be engineered through 30% substitution of additive material for Portland cement that resulted in no decrease in mechanical performance, but with an embodied energy savings of 9% per kg of material. As an example application for the Al-Hamra tower, an 80-story building that is the world's tallest sculpted concrete structure in Kuwait consisting of 490,000 metric tons of concrete, this would result in a huge embodied energy savings within the structure.

Feng Department of Civil Engineering and Engineering Mechanics Data Science Institute Columbia University ABSTRACT With recent technological breakthroughs, making bridges smart is no longer a dream. This talk will first review the lessons that I have learned from bridge structural health monitoring research over the last two decades.

Clearly this is a major issue as the risks are rising because densification exposes larger populations to hazard events (e.g., earthquakes, hurricanes, terrorist activities) with infrastructure failures coming at higher costs.

Recent initiatives to develop robust systemlevel asset management tools using service life modeling have identified needs for improving our understanding of deterioration of critical infrastructure such as airfields, bridges, locks, and dams. To inform asset management and enable decision making, fundamental science to understand deterioration, the current state of distress, and to predict future deterioration is needed.

CITY AS TERRESTRIAL CRUSTACEAN: STRUCTURAL ENGINEERING AND RESILIENT CITIES P.R. Brown ABSTRACT This paper responds to a specific question raised regarding: "How are cities thinking about the role of technologies and structural engineering for future resilience?

Resilient infrastructure systems must have performance goals which are consistent with community resilience objectives, for normal operations and following extreme events. For extreme events, the performance goals should match what the local communities find acceptable performance they are willing to pay for.

The LADWP has taken an approach to implement pilot studies for available seismic resilient pipe and lining systems to investigate their application toward developing a SRPN while encouraging the development and importing of new seismic pipe technologies to create a national and international self-sustainable resilient pipe marketplace. Related resilient pipe guidelines and standards for design, testing, and installation practices are under development through a collaborative effort between water agencies, pipe suppliers, the American Society of Civil Engineers, and the pipe testing experience developed by Cornell University.

All this said, there remain challenges in data sharing between public and private entities, with cybersecurity and denial of service, and in having benefits unevenly flow to affluent and distressed populations. This talk will cover the changes, opportunities, and challenges of the digital world as it adds and subtracts resiliency from our communities.
