波形钢腹板-双管弦杆-混凝土板组合梁有限元分析

Finite Element Analysis of the Composite Beam with Corrugated Steel Web,Double Steel Tubular Chord and Concrete Slab

利用ABAQUS有限元程序对波形钢腹板-双管弦杆-混凝土板试验梁进行有限元模拟分析,计算结果与试验结果吻合良好,验证了有限元模型的正确性。分别以下弦管内混凝土填充范围、下弦钢管壁厚、波形钢腹板厚度为参数,分析各参数对该组合梁受力性能及结构承载力的影响。

The ABAQUS finite element program was used to establish finite element analysis model of the test beam with corrugated steel web （CSW）,double steel tubular chord （DSTC） and concrete slab （CS）. The calculated results are in good agreement with the experimental results,which verifies the correctness of the finite element model. The following parameters,namely the concrete filling area,the wall thickness of the lower chord steel tube,and the thickness of the corrugated steel web,were respectively used to analyze the influences on the mechanical properties and structural bearing capacity of the composite beam.
