The United Nations Office for Disaster Risk Reduction reported that the 2011 natural disasters, including earthquake and tsunami struck Japan, resulted in $366 billion direct damages 29,782 fatalities worldwide. Storms floods accounted up to 70% of 302 disasters worldwide 2011, with earthquakes producing greatest number fatalities. Average annual losses States amount about $55 billion. Enhancing community system resilience could lead massive savings through risk reduction expeditious...
Natural disasters in 2011 alone resulted $366 billion (2011 US$) direct damages and 29,782 fatalities worldwide. Storms floods accounted for up to 70% of the 302 natural worldwide, with earthquakes producing greatest number fatalities. Managing these risks rationally requires an appropriate definition resilience associated metrics. This paper provides a that meets set requirements clear relationships reliability risk as key relevant The proposed is intension type, which highest order....
Commonly‐used structural reliability models are reviewed, and the advantages limitations of each method discussed with help a practical example. A pressure vessel is designed against wind loading. This example selected because limit state equation nonlinear speed has an extremely skewed distribution. Although First‐Order Second‐Moment may be sufficient in many problems, risk involved still unknown, even relative sense, unless linear all variables normal. In that Advanced several advantages....
Climate change can accelerate infrastructure deterioration in coastal areas because increased temperature and humidity promote steel corrosion. This study (1) projects corrosion rate changes for reinforced concrete structures 223 counties, (2) assesses the impact of on useful life structures, (3) evaluates direct economic losses due to shortened highway bridges over period 2000-2100. The results show that may decrease by 1.7-2.7% under representative concentration pathway (RCP) 8.5 0.7-1.1%...

ABSTRACT Uncertainty in the basic load and strength variables of a ship structure can significantly affect structural performance safety. Variations strength, effects greatly impact reliability system. Understanding including this variation, or uncertainty, design analysis structures requires use reliability‐based assessment methodologies. For example, is based on nominal values for such as yield stress material, plate thickness, modulus elasticity, etc. The actual these are often different...
This article proposes a quantitative risk assessment and management framework that supports strategic asset-level resource allocation decision making for critical infrastructure key protection. The proposed consists of five phases: scenario identification, consequence criticality assessment, security vulnerability threat likelihood benefit-cost analysis. Key innovations in this methodology include its initial focus on fundamental asset characteristics to generate an exhaustive set plausible...
Abstract As states, cities, tribes, and private interests cope with climate damages seek to increase preparedness resilience, they will need navigate myriad choices options available them. Making these in ways that identify pathways for action support their development objectives require constructive public dialogue, community participation, flexible ongoing access science- experience-based knowledge. In 2016, a Federal Advisory Committee (FAC) was convened recommend how conduct sustained...
The quest to answer the longstanding question of how safe is enough has led an evolution design philosophies. traditional philosophy been based on ensuring that system capacity exceeds demand. This manifested in such methods as allowable stress (ASD) and load resistance factor (LRFD). level safety these commonly calibrated acceptable practice using structural reliability methods. Such approach aims balance life construction costs works relatively well for service loads under which strength...
In the last decade, detection and attribution science that links climate change to extreme weather events has emerged as a growing field of research with an increasing body literature. This paper overviews methods for event (EEA) discusses new insights EEA provides infrastructure adaptation. We found can inform stakeholders about current risk, support vulnerability-based hazard-based adaptations, assist in development cost-effective adaptation strategies, enhance justice equity allocation...
Probabilistic methods are being used increasingly in construction engineering. However, when a parameter is expressed linguistic rather than mathematical terms, classical probability theory fails to incorporate the information. The variables can be translated into measures using fuzzy set and system theory. A management problem, i.e., estimation of duration an activity, solved this In order implement proposed technique, various membership functions need estimated judgment or with assistance...
