Urban Vulnerability and Earthquake Risks Incorporating Sustainability

Abstract

Amidst the backdrop of rapid global urbanization, this research delves deep into the nexus of urban vulnerabilities, seismic challenges, and sustainable infrastructure. As cities sprawl, the need to adapt and refine traditional building techniques becomes evident, especially in the quest for seismic resilience and ecological sustainability. The study introduces the innovative 'Sustainable Seismic Design' framework. A core component of the research is the quantitative material evaluation. Materials, notably Engineered Timber and Concrete, are assessed on their seismic resistance—measuring their capacity to withstand seismic forces and dissipate energy during earthquakes. Concurrently, their environmental impact is evaluated, considering factors like energy consumption during production, emissions, and recyclability. Engineered Timber emerges with a commendable 50 % higher environmental score, underscoring its eco-friendly nature compared to Concrete. Further, the research illuminates the often-overlooked geotechnical elements, such as soil characteristics and groundwater dynamics, that can amplify seismic vulnerabilities. The advocacy for green geotechnical strategies is accentuated, with the post-seismic rebuilding endeavors in Christchurch, New Zealand, serving as a practical exemplar of the benefits of this integrative strategy. In essence, the study champions policy adaptations that seamlessly weave sustainability into seismic construction standards and geotechnical practices, setting the stage for urban habitats that are both resilient to earthquakes and champions of green initiatives.
