Sustainable Design Considerations in Earthquake Engineering

Abstract eng:
The primary goal for seismic-resistant design of ordinary structures is to prevent collapse and loss of life. Thanks to extensive experimental, theoretical and computational research, engineers are able to design wide array of structures capable of withstanding numerous cycles of inelastic deformation during strong earthquakes with minimal probability of collapse. However, this approach, while providing a high degree of life safety, is expected to result in substantial structural and nonstructural damage. The economic and social impacts of this anticipated damage could be far-reaching and profound; and likely contrary to the basic principles of sustainable development increasingly advocated by many owners, architects and policymakers. However, a range of quantitative tools, such as performance-based evaluation, and advanced structural system concepts, can easily extend current earthquake engineering design practices consistent with and supportive of emerging trends related to sustainable design. This paper discusses some of the underlying issues and highlights several approaches to achieve structural systems that are more sustainable.
