摘要：

At present, scholars at home and abroad have conducted more research on conventional steel-concrete composite bridges and conventional oblique bridge, but there is relatively little research on long-span diagonal steel-concrete composite beams that appear in engineering. The article combines specific engineering examples and uses the finite element analysis software Midas Civil to establish a single beam model and a beam grid model for calculation. Through comparative analysis of the two calculation results, it is concluded that using a single beam model to simplify the calculation is biased towards safety, and due to the action of the diaphragm and crossbeam, the torque in the calculation results of the beam grid model is greater than that of a single beam. For structures with long oblique angles, the beam grid model should be used for inspection.
