Simplified Life Cycle Cost Estimation of Low-Rise Steel Buildings Using Fundamental Period

In the current study, a simplified seismic life cycle cost (LCC) estimation procedure is proposed utilizing mean values of structure’s main input variables. The variables building are used for constructing relationship between structural fundamental period (T) and an average LCC (LCCavg). Using actual properties related to damage probability, T–LCCavg obtain final (LCCfin). equivalent single degree freedom (ESDOF) model SAC-FEMA framework utilized probability calculation. dispersion measure in demand approximately calculated based on plus one standard deviation hazard response spectrum, and, then, verified through nonlinear time history (NLTH) analyses original structure. Five three-story steel buildings as case studies verification method. analysis results indicate that provides reasonable estimations low-rise dominated by mode vibration.
