Research on Structural Performance and Economic Cost Analysis of Steel Plate Wall Core Tube and Concrete Core Tube
This article studies a novel composite core tube system using steel plate columns at the corners of the core section,which can a-chieve better structural performance and constructability.And the proposed core tube was used for nonlinear section analysis and three-dimen-sional structural analysis of the prototype core tube section and the super high-rise building,respectively.The results show that compared with traditional RC core tubes,the use of angle steel plate columns provides better structural bearing capacity,which makes the wall thickness thin-ner,uses fewer steel bars,shortens construction time,and can reduce economic costs.
