Abstract
Construction records of two high-rise RC buildings were analyzed in detail for rationalization of construction of similar buildings. 1) Based on the actual period of time for each works, the prediction formula of the total duration of construction works for each floor of buildings was established. 2) Employment of members that have a non-structural portion such as PCF should be avoided because it is undesirable from the point of view of both the cost and the global environment. 3) Adoption of the pre-cast concrete members as joint panels of perimeter columns and beams will be the most effective way to reduce the total duration of the construction of high-rise RC buildings with high strength concrete. 4) When the different specified strengths of concrete were used, the effectiveness of adoption of pre-cast concrete members will vary from the place of the adoption. 5) It was confirmed that the adoption of the pre-cast joint panel members could be effective from calculation of the total construction time of the two buildings.
