Abstract：
This paper introduces the whole life cycle and the meaning of the whole life cycle cost and economic benefits, cost analysis, and analysis process and analysis method, a high-rise building engineering example has carried on the brief analysis, by comparing the three different structure scheme than the maximum displacement of vibration mode of the periodic table and found that although all design parameters of the three kinds of scheme can satisfy the requirements of specification, but considering the seismic performance requirements and dosage of steel consumption, standard layer reinforced whole life construction costs, such as requirements, finally decided to adopt steel reinforced concrete frame-reinforced concrete core tube structure as the final design plan.
