ارزیابی جایگزین های مجدد ساختمان از منظر پایداری

Buildings primarily provide shelter and acceptable comfort for its intended occupiers and they should also provide adequate protection in case of hazards. Unfortunately, in case of seismic events it is observed that in many cases earthquakes caused considerable damage to residential and commercial buildings, public facilities and infrastructures with substantial casualties due to inadequate engineering and faulty in construction practices. In this study, a reinforced concrete residential building that collapsed in 1999 Kocaeli Turkey Earthquake (MW 7.4) is focused and investigated using current seismic code. Afterwards, building is virtually retrofitted considering architectural plan and using common retrofitting methods for satisfying current seismic code requirements. These retrofit alternatives are then evaluated from structural, cost and environmental aspects and outcomes are discussed. Since structural components that are used in retrofitting the building consumes natural resources and responsible for energy consumption, sustainability criteria should be directly included in the retrofitting requirements. Consequently, structural engineers are able to use natural resources efficiently and reduce the environmental impacts in retrofitting.
