Abstract
A two-stage energy dissipation type shed tunnel support structure connected by a principle of Dougong and a design method thereof are provided. The two-stage energy dissipation type shed tunnel support structure includes a Dougong joint domain, crossbeams and columns. The Dougong joint domain includes section steel members, wavy-wall cylindrical elastoplastic buffers, U-shaped sliding connecting troughs and high-strength bolts. Multiple layers of the section steel members are orthogonally stacked to form a Dougong shape, the wavy-wall cylindrical elastoplastic buffers are arranged between adjacent layers of the section steel members, and the U-shaped sliding connecting troughs are arranged at upper and lower ends of the wavy-wall cylindrical elastoplastic buffers, which realizes a connection between the wavy-wall cylindrical elastoplastic buffers and a section steel in two orthogonal directions. Under an impact of small energy rockfalls, an elastic deformation of the Dougong joint domain is used to achieve a buffering.
