Recently construction of high-rise buildings is increasing in cities to maximize the usage of land in Korea. Since structural<br/> frame work in high-rise buildings have the largest component of duration and cost, accelerating schedule and reducing<br/> construction cost are important factors in the structural frame work. Therefore, the duration and construction cost trade-off are<br/> necessary to complete a structural frame economically. Accelerating schedule is more important than reducing construction cost<br/> in Korea because duration of high-rise buildings have large risk in finance. For accelerating schedule, the cycle time of<br/> structure work is shortened by these two methods: (1) forms are stripped early without cracking the concrete and increasing<br/> the deflection of slabs or girders by using the higher strength concrete than the designed one; (2) the number of form sets is<br/> increased. Although using the higher strength concrete and increasing the number of form sets result in increasing the direct<br/> construction cost, the budget cost is decreased by shortening the cycle time of structural frame work.
