基于XFEM的渡槽单向地震动作用下裂纹开展分析
Analysis of crack growth of aqueduct under effect of single dimensional earthquake force based on XFEM
摘要
Abstract
Taking bent-type aqueduct as study object,the paper established a linear elastic calculating model with two-dimensional aqueduct of rubber bearings based on ABAQUS platform with XFEM.It calcuated the growth and extension of cracks and the equivalent stress of aqueduct structures during dynamic circulating process under different seismic waves,and analyzed the range of cracks and the damage degree of aqueduct structures.The results show that XFEM can better simulate the crack dehiscence and expansion of aqueduct structure.Both the joints between beam and column,and the bottom of column are the weak parts of anti-seismic of aqueduct structure.关键词
