What are the best practices for ensuring a structure is resilient to natural disasters?

To ensure a structure's resilience to natural disasters, best practices include designing for worst-case scenarios, building strong foundations, elevating above flood levels, using impact-resistant materials, designing for redundancy, incorporating green infrastructure, and considering the building's context. Site selection best practices involve assessing potential risks, elevating above base flood levels, using a multi-hazard approach, and considering community planning and resilience. By following these practices, structures can better withstand natural disasters and minimize damage.

Risk assessment and site selection are critical to identify potential hazards and mitigate their impact. Incorporating robust structural design and engineering techniques, such as earthquake-resistant foundations, reinforced materials, and flexible building components, can enhance resilience. Implementing resilient infrastructure systems, including reliable utilities and emergency response plans, further fortifies the structure against disasters. Additionally, ongoing maintenance and monitoring protocols help detect vulnerabilities and ensure the structure remains resilient over time. Lastly, community engagement and education play vital roles in fostering preparedness and resilience at both individual and societal levels.

Resilience to natural disasters is crucial for reducing risks and disaster losses. Best practices for resilience include: *Preparing and planning for adverse events *Accessing risk and vulnerability information *Developing proactive resilience strategies *Promoting community engagement and coalition *Using disaster loss data for a long-term commitment Key components of a resilient nation include reducing disaster risks, managing risks, and building capacity from the community level. Different measures can help manage disaster risks, such as structural and nonstructural measures.

Structural systems should be designed to resist natural hazards, including gravity and lateral loads, and transfer them to the foundation. Wind and seismic loads are related to the building's risk category and location. Wind speeds are calculated based on topography and the openness of the building envelope. Lateral load-resisting systems, such as moment frames, braced frames, and shear walls, should be designed based on the building's membrane type and the areas of the building that are affected. In tornado-prone areas, buildings can provide 'safe rooms' or shelters as areas of refuge.

Durability means selecting quality materials and systems that can withstand wear, decay, and degradation over time. Redundancy involves designing systems that can redistribute loads and absorb energy during extreme events. Maintainability involves selecting materials that are easily replaceable or repairable and designing for regular maintenance and restoration after damaging events. Site selection should consider potential hazards, while material selection should prioritize resilient materials. Structural systems should be designed to withstand gravity and lateral loads, while non-structural elements should be sited and protected from hazards. Climate change and variability should also be considered in design strategies.
