Giant Concrete Filled Steel Tubular Column Construction Technology of Cold-zone for Ice-snow Complex in Ganlu Mountain Literary and Creation City
The area,height,vertical and horizontal dimensions of the steel roof in the cold-zone for Ice-snow Complex in Ganlu Mountain Literary and Creation City are large,and the lower part is a large space barrier-free ski area,the design and construction of its vertical support structure are particularly important.Through the comparison and selection of different schemes,a reasonable scheme of elevated frame column is put forward,and the parameters and structure of concrete filled steel tubular column are determined by IDEA StatiCa finite element software.The ring beam joints connected to the concrete beam,the upper and lower chord joints connected to the steel roof,and the column foot joints connected to the foundation are detailed designed to solve the problem of complex joint structure,and a set of perfect construction technology of giant concrete filled steel tubular columns is formed,which has a good application effect in practical engineering.
