PREDICTIVE METHOD FOR ECONOMIC INDICATORS OF HIGH-RISE FRAME-TUBE STRUCTURES

With the rapid development of high-rise frame-tube office buidings in domestic large and medium-sized cities, it brings the problem about the study of quantities. Traditional structural design can meet the requirements of all kinds of standards, but it wastes materials, which is now taken seriously. Structural optimization design can save materials. This paper carries structural optimization design on eight high-rise frame-tube structures, and proposes a predictive method for concrete and steel-bar dosage of high-rise frame-tube structures after analysis. The predictive method makes it possible to predict the dosage before the structural design without the tedious budget process. The predictive value is economical and reasonable, and it can provide reference for structural design and construction in the future.
