| Abstract: | Based on the analogy orthotropic plate principle,traverse distribution function under the design load is theoretically deduced and the piecewise function to fitting curves is used.This computation method has greatly improved not only the computational efficiency but also the precision.Furthermore,the deduced transverse distribution expression is also available to be applied in the modular programming,which has laid a foundation work for the engineering software analysis. |
