Description

technical field [0001] The invention relates to the technical field of bridge engineering structure simulation simulation, in particular to a MIDAS rapid modeling method based on MATLAB. Background technique [0002] As a special design software for bridges, Midas Civil combines various specifications at home and abroad, and the interface design is interactive, which is suitable for the overall calculation of bridges of various bridge types. Midas Civil is widely used in engineering design, but it is rarely used by scientific researchers. There are two main reasons: first, Midas Civil entity simulation and detailed analysis functions are weak, and it is basically a calculation software for linear elastic small deformation beam elements. Only a small amount of non-linear corrections that may be used in the design are added; second, the parameter analysis method is commonly used in scientific research work, and the modification of Midas Civil software is relatively complicated...
