Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Example 1

An ultrahigh-toughness concrete section steel combined structure is shown in fig. 1-6 and comprises a vertical column 100 and a cross beam 107, wherein the vertical column 100 and the cross beam 107 are fixedly connected through a connecting piece 109, the vertical column 100 is composed of a section steel column 101 and a stud 102, the cross beam 107 is composed of an i-shaped steel 104 and the stud 102, the stud 102 is connected to the surfaces of the section steel column 101 and the i-shaped steel 104, the i-shaped steel 104 is arched, a steel cable 108 is fixedly connected to the lower surface of the i-shaped steel 104, and steel fiber concrete 103 is poured on the vertical column 100 and the cross beam 107.

The studs 102 are evenly distributed on the surfaces of the upright 100 and the cross beam 107.
