摘要
Abstract
This study focuses on a practical utility tunnel which is built under the road and includes beam and column construction in Zhengzhou city,in which the mechanical property of the whole structure and related members have been analyzed using finite element software ABAQUS,and various load combinations have been considered.The results show that the whole structural deformation and deflection of related members are small,which can satisfy serviceability requirements.The maximum tensile stress of several concrete exceeds the standard value of axial tensile strength,which indicates cracking of concrete.The connection of the top slab and frame column is in the most unfavorable loading state under the load case 1-1 and 2.The compressive stress of the frame column concrete is greater than the design strength,which implies that original connection cannot satisfy design requirements.The maximum stress of steel is less than the design value.According to the analysis results,this study suggested enlarging the haunched plate size at the connection of top slab and frame column to ensure the safety of the utility tunnel,which will provide references to the design and construction of such utility tunnels.关键词
