Checking Computation for Bracket Structure of Jinqinggang Bridge
In order to ensure the safety of bracket structure during the cast-in-place construction of No.0 and No.1 piece concretes, this paper makes use of probabilistic limit state method to do the checking computation. According to the design drawings of bracket structure of the Jinqinggang bridge and the actual load case, the analytical model is founded by the finite element analysis software MIDAS/CIVIL. The results show that the stresses of all parts of the bracket structure including the concrete local compressive stress and the tensile stress of embedded steel bar are less than the allowed value of corresponding materials, but the deformation of the steel moulding plate is larger than standard allowance value. The weld joint between upper chord and slanting pole with embedded steel plate satisfies the design requirement.
