Abstract:
The actual value of structures should not be evaluated only based on initial cost, because failure cost and economical losses due to corrosion and natural hazards can be catastrophic. When a long life Performance of a structure is expected, life cycle cost analysis is the best way to assess and compare economic value of different design choices. The main purpose of this work is investigating the effect of shear walls in limit state cost and total cost . Results demonstrate that shear walls can reduce limit state cost up to 70 percent . Furthermore the influence of increasing thickness of shear walls and effect of reducing dead loads in total life cycle cost is discussed. It is shown that using minimum thickness of shear walls and reducing dead loads doesn’t necessarily lead to minimum amount of total cost. Also endurance time method is used to accomplish nonlinear dynamic analysis which considerably decreases the number of time history analyses
