The Research Of Modeling Test And Calculation Method About Wide Bearing Continuous Beam

With the development of the large-scale structure style about standingpile wharf, wide bearing continuous beams are using in some practice standingpile wharf engineering. But the method about continuous beam which the design and construction norm of standingpile wharf apply, doesn't consider the influence of bearing width on curving force, and choose different calculation span on curving and shearing force, it cause some difficulty on engineering design. To satisfy the need of engineering design, it is necessary to study on the loading characteristic and calculation method about wide bearing continuous beam.Based on the analysis of "wide supporting" method, this article bring forward wide bearing double parameter method, based on FEM and imaginary power theory, educed element append stiffness matrix and the method how to do the internal force about wide bearing continuous beam, and workout the procedure about the "wide support" method, the multi-bearing method which consider node field elasticity and the double parameter method ; combined with the results about modeling test, it compared with plane method's and ANSYS space element method's results; based on internal force distribute rule and influence factor of beam, I educed the simple method under equal loading about wide bearing beam: while α >0.2, the minus curving force can replaced by the bearing brim results which calculated by method of elasticity bearing continuous beam, while α ≤0.2, the minus curving force can reduced by "BEILUN cut peak" value; the positive curving force can reduced by coefficient; the maximal shearing force on bearing can considered by bearing brim value which computed by method of elasticity bearing continuous beam.
