Summary | The growth of the construction industry led to the publication of guidelines and codes that govern the analysis and the design of structures ensuring the safety of users against various types of actions. Nevertheless, issues concerning the actual cost of each structure, including the occasional cost for repairing seismically induced damage have not been fully integrated in the analysis and design procedure. Moreover, given the need to decrease the energy consumption and the carbon footprint of human activities, it is necessary to examine structural cost in life cycle terms. This implies that the cost estimation should include the initial construction cost, the expected repair cost due to earthquake damage, the energy consumption cost and also the decommissioning cost. The present work aims at investigating the life cycle cost for multi-storey steel structures. The results of non-linear time history analyses are utilized in order to calculate the earthquake damage repair cost as per FEMA P-58, and the estimated cost is combined with the annual energy consumption cost calculated according to the ANSI/ASHRAE 140 standard.
