Buckling of Double-T Construction Elements for Bridges in Case of Complicated Loading

The Baltic Journal of Road and Bridge Engineering, 2009
This paper analyzes the stability of double-T elements with complicated loading under bending moment and extra torsional moment. In case of simple bending, long elements and elements of small cross-section are under bending and torsion moments.

Optimization Study on Longitudinal Joints in Quasi-Rectangular Shield Tunnels

Applied Sciences, 2021
There are large bending moments in quasi-rectangular shield tunnels due to their deviation from the circular shape, and as for other types of shield tunnels, the longitudinal joints are the most critical parts in the lining structure. A new type of joint
