The mechanical characteristics and the Brinell hardness of the steel, for the two main elements, were determined in advance. In particular, the following was measured: - The steel of the hanger bars was A105 grade, with a nominal yield strength of 355 MPa and a tensile strength of 510 MPa...
5. Bridge Safety Evaluation Based on Sensing Information Based on the response information, theoretical calculation analysis, mathematics, and mechanics, the safety evaluation of structures can be achieved via the changing characteristics indexes of the structure itself, its response, and trends.
