| Abstract: | The space finite element calculation model is set up for the truss double-guiding-beam erector based on the engineering cases.The international advanced finite element program-MIDAS especially for the bridges is used for the static calculation and analysis of the guiding beam,separately calculating the structural stresses and displacements in various testing conditions,and analyzing and comparing the measured results.Based on the above,the article appraises and evaluates the bearing capacity of the erector ... |
