Abstract

Abstract

An innovative structure with perforated steel plates integrated into the main girder flanges of traditional simply-supported-to-continuous composite girder bridges was proposed to address the issue of their concrete decks in the negative moment regions being prone to cracking. Through static tests and finite element simulation, the mechanical behavior and crack development law in the negative moment regions of the novel structural form were studied systematically. Based on test results and parametric analysis data, the corresponding calculation method of bending capacity was established. A calculation formula of the bending capacity was proposed for the middle bearing section in this novel structure simply-supported-to-continuous composite girder. Test results show that the ultimate bearing capacity of perforated steel plate components is increased by 71% compared with that of ordinary components. The mid-span slip of perforated steel plate components is smaller than that of ordinary components under the same load. A certain amount of retraction of mid-span slip occurs during unloading, suggesting that perforated steel plates contribute to enhancing ductility of the structure. During the negative moment loading process, the perforated steel plate components show a slower crack development rate and fewer cracks than ordinary components. By comparing the theoretical and test results, the calculation formula can be used to predict the ultimate bearing capacity of simply-supported-to-continuous composite girders with perforated steel plate components. The perforated steel plate significantly enhances the ultimate bearing capacity and crack resistance in the negative moment region, while also improving ductility of the structure to a certain extent. Reference can be provided by this study for the design of similar structures in the future.
