摘要
The instability problem of steel-concrete composite beams will occur in the negative bending area, and different codes get different results for beams bearing negative bending moment on stability. In this paper, the MATLAB is used to analyse the parameter sensitivity of span, height-thickness ratio of web, concrete slab reinforcement ratio based on Eurocode 4 and China Code for Design of Steel and Concrete Composite Bridges. Through a large number of data analysis, the influence degree of each parameter on the stability is determined, and the results of the two codes are compared, which provides a basis for the design of the stability in the negative moment zone of steel-concrete composite beams.
