Özet

Seismic structural design of X-braced steel buildings using life cycle cost analysis aims to reveal the most appropriate structural solution for both satisfying economic aspects and earthquake resistant design code requirements among a number of variant solutions accounting architectural concerns. In this study, five storey X-braced steel building with three different X-bracing configurations is designed using various base shear values and the total cost of each design of three configurations is calculated for different earthquake intensities. Initial costs and the cost of the expected damages caused by future earthquakes are determined for each X-bracing configuration. The maximum interstorey drift ratio is selected as seismic performance parameter for satisfying earthquake code demands and evaluated through nonlinear static analysis. The optimum X-bracing configuration is determined by using the balance between the initial cost and the lifetime earthquake damage cost.
