The Analysis Of Calculational Method And Model Experiment About Standingpile Wharf Bent With Big Pile Cap

The standingpile wharf is one of the three major structure forms of the quay, it has been applied quite extensive in our country. With the changes of the use demand and natural conditions of the quay, the structure of the quay had happened greater changes relative to the past. At the same time, the count of pile in the nodal place of the crossbeam is increasing correspondingly, the size of pile cap become heavy gradually in nodal place, the bearing width in longeron and crossbeam is strengthened gradually too. Therefore for crane grider and crossbeam, have met new problem that how to calculate internal force of the beam while meeting the wide bearing.The design and construction norm of standingpile wharf (JTJ267-98) calculate longeron and crossbeam by continuous beam with the elastic support. But it can't consider the influence of the wide bearing. With the increase of the width and the rigidity of bearing, the actual internal force of beam and standardize result of calculation have heavy difference, bring to engineering design difficult, necessary to go on special research about his computing technology.In order to draw a correct conclusion about internal force distributing of crane grider and crossbeam in the wide bearing structure, and offer the scientific basis for design for the future and the revision of norm. At the foundation of combining "the model experiment study of beam with wide bearing " subject, this paper has carry on deeper research to this kind of structure through the level method, Ansys finite element simulation and model test. Find through the analysis of this thesis: The result of considering pile cap with elastic joint panels, the result of calculation of Ansys finite element about wide bearing and the result of the test are identical. To the wide bearing structure, The computing technology of the finite element of Ansys and considering pile cap with elastic joint panels is desirable. Finally it has analyzed the project instance by the method of Ansys finite element and continuous beam with the elastic support, besides, have drawn some useful conclusions that can offer the reference for similar project and the revision of norm.
