Dynamic ultimate capacity analysis of rectangular girder under hammer impact.

The dynamic failure and ultimate capacity analysis of rectangular girder under bending moment has not been fully studied. In this paper, a rectangular girder scaled from actual ship deck structure is selected as the study objective to analyze the dynamic failure and ultimate flexure capacity. The dynamic response under hammer drop impact is studied, and then two criteria of dynamic ultimate flexure capacity of the girder are proposed based on the bending moment in section and permanent deformation. The novelty of this paper is the proposed evaluation criterion of dynamic ultimate capacity. [ABSTRACT FROM AUTHOR]
