Abstract

Abstract

In order to study the buckling performance of webs of castellated steel-concrete composite beams under the combined action of negative bending moment and shear force, two castellated steel-concrete composite beams and one castellated steel beam were designed for static loading test. Based on the test results, the nonlinear finite element model of castellated steel-concrete composite beam with initial geometric imperfections was established. The finite element model was verified, and the effects of parameters, such as opening ratio and web height-thickness ratio, on the buckling performance of castellated steel-concrete composite beams were analyzed. The results showed that concrete slabs on beams could increase the yield load and ultimate load of specimens, and improve the buckling resistance of webs to a certain extent. The web height-thickness ratio had a significant effect on the buckling performance of webs. Reducing the web height-thickness ratio could improve the buckling load of webs and enhance the buckling performance of webs of specimens, The opening ratio had a great influence on the buckling performance of webs, the buckling load of composite beams increased with the decrease of opening ratio. When the height-thickness ratio was below 58, the strength failure of castellated steel-concrete composite beams occurred before the stability failure.
