Abstract

To investigate the anti-explosion performance of steel beam-slab protective door under underwater explosion impact, a three-dimensional numerical model for the steel beam-slab protective door under underwater impact load was established, and the effects of constraint conditions, height and thickness of the flat web in the skeleton beam, width and thickness of the flange plate on its anti-explosion performance were analyzed. The calculation results demonstrate that the frame beam at the edge of the protective door is the most vulnerable component in terms of anti-explosion performance. It is susceptible to various failure modes, including buckling deformation of local frame beam, overall flexural failure, compression-bending failure, and warping failure of frame beams on both sides; the variation in constraint conditions has a notable influence on the anti-explosion performance of the structure; increasing the height and thickness of the flat web results in a reduction of approximately 20% in the peak displacement of the structure. But simply increasing the width and thickness of the flange plate has a limited impact on the structural resistance to explosions.
