DEVELOPMENT OF SUSTAINABLE SEISMIC STRUCTURES

Seismic sustainability (SS) is the most challenging issue confronting development of resilient citiesin earthquake prone regions of the world. Sustainable seismic design (SSD) with a view to economicsand environmental protection is the most challenging issue confronting structural engineersworldwide. In the present context design implies planning for controlled seismic resistance,environmental protection, construction economy and Post-earthquake Realignment and Repairs,(PERR). In SSD the practicality of PERR is as important as the relevance of the theoreticalassumptions, therefore, the non-lateral resisting items are carefully designed not to partake in seismicresistance, nor hinder the realignment effort. All Earthquake resisting structures (ERS) are designedfor practical, residue-free recentering while their energy dissipating components are detailed to remainrepairable/replaceable after the event. The authors hope this, and related articles will form the basis ofSSD guidelines for earthquake prone resilient cities.
