摘要
Abstract
The finite e1ement mode1 of the main bridge of Xinbian-he river bridge in Suzhou was bui1t for theoretica1 ca1cu1ation of static 1oad experiment, based on which the test conditions and contro1 sections were determined. The section stress of the main beam and the main tower, the def1ection of the main beam and the cab1e force increment were tested under the most disadvantage 1oad in the static 1oad experiment. The coeffi-cients of stress ca1ibration, def1ection ca1ibration and cab1e force ca1ibration are 0.24-0.93, 0.61-0.68 and 0.25-0.58 respective1y, which are 1ess than the theoretica1 ca1cu1ation va1ues. The resu1ts show that this bridge is safe with good rigidity and strength under the designed 1oad.关键词
