Study on Rational Design Method of Composite Segment

Abstract

Composite segment is the steel structure, which is filled with high flowability concrete. The cross section of segment can be made small because its stiffness is bigger than that of RC structure and others. Steel shell and concrete are combined by the stud bolts welded on the inner surface of the shell. Some loading tests were carried out to verify the structural advantages of the segment and examine the propriety of reinforced concrete theory and three dimentional finite element method. This paper shows the rational design method of composite segment.
