Fracture Analysis of Crack Propagation on the Diaphragm of Steel Bridge Structures

Truyen, Tran The / Hieu, Nguyen Duc / Tung, Bui Thanh / Quoc, Doan Bao / Anh, Nguyen Thuong

The crack failure occurring on the steel diaphragm of Vam Cong Bridge during construction stage in Viet Nam has raised issues that it is necessary to deeply understand the behavior of steel structures in the construction process along with the boundary conditions of structures and especially pre-defects within steel materials. Fracture theory should be applied to analyze the brittle failures in this case which it is totally different from conventional failure at plasticity state. The investigation analyzes the fracture mechanism of a typical steel diaphragm structure that is similar to the diaphragm member of main span in the Vam Cong Bridge. Initial cracks within steel material being used for the diaphragm will be considered. The result would contribute to clarify the reasons of the brittle failure in steel bridge beams as well as crack patterns with different boundary conditions.
