The Quantity Variations of the High-Strength Reinforcing Bars on the Underground Parking in a Rigid-Frame Building

摘要

It is dealt with the quantity variations of high-strength reinforcing bars in the underground parking spaces. The purpose of this study is to investigate the quantity variations of the high-strength reinforcing bars on the underground parking spaces in a rigid-structure building. Recently, constructing high-rise buildings and long-span structure in the architecture, engineering, and construction industry (AEC industry). However, there are a number of difficulties such as excessive reinforcing bars arrangement, failure of concrete quality management, unnecessary quantity take-off and so forth, when these types of structures and buildings are formed utilising normal strength reinforcing bars and concrete. As skyscrapers and long-span structures are getting more common in the AEC industry, it is widely applied high strength reinforcing bars, cement and supplementary materials to sustain durability and stability. The test results indicate that it would be possible to achieve the reduction of reinforcing bars arrangement and lowering the amount of bar arrangement when the high-strength rebars were applied to the underground parking spaces in a rigid-frame structure. Moreover, the reduced amount of bar arrangement will make it possible to improve workability and constructability of reinforced concrete structures.
