Abstract In order to investigate the fracture properties of low carbon steel after seawater immersion and reloading, Q235 steel were made into a series of rectangle cross-section beams with prefabricated crack, and the specimens were divided a few group according to the history of its loading or reloading before and after soaking in room temperature seawater. The fracture behavior of specimen was analyzed in different test conditions, and their bearing capacity was compared with each other for loading before and after soaking. The length of plastic zone of specimen which was soaked in seawater for short-term after loaded into plastic zone became shorter and the material was more brittle.
