The purpose of this study is to examine economical efficiency of high-strength concrete application in high-rise RC buildings. Use of high-strength concrete will increase material cost. On the other hand, member size will be reduced due to increased sistance capacity of member, leading to increase of floor area. In this study, three types of plan layout are used: plan with core-wall only, symmetric plan with column and core-wall, and asymmetric plan with column and core-wall. And six types of concrete strength combination are applied to 30, 40, and 50-story buildings. The concrete strength has changed three times through the height of buildings: two times at the lower half of building height, and one time at the upper half. The economic efficiency of each model is compared by estimating financial value of increased usable floor area and increase of material cost. The results of this study can be summarized as follows: 1) Simple plan with wall only model which is not modeling whole building frame showed different behavior with other models. Therefore, it can not be a substitute for realistic modeling of a building. 2) Among six types of concrete strength changes a type with high strength concrete applied in the upper half of stories of building was most efficient. In this study, only effect due to reduced member size is accounted into the estimation of financial merit for application of high strength concrete. Further study that includes construction cost such as formwork, labor may be needed to find out more realistic benefit of high strength concrete application in high-rise buildings.
