Implementation of Data Conversion Interface Between Midas and DUT2014 Structural Model

摘要

DUT2014 is a computational program developed by our team for the elastic-plastic time history analysis of super high-rise building structures. The integrated platform code is open source, which has all the materials and elements for the structural analysis of super high-rise buildings. Moreover, the integrated platform has a new element state transition algorithm (STP), which greatly improves the computational efficiency of elastic-plastic time history analysis. Midas is a finite element analysis software, which has good elastic analysis function and non-linear analysis function, and it has good pre-processing function. Preprocessing of DUT2014 is a command stream format in text format, and its modeling function is relatively cumbersome. In order to realize the customization of DUT2014 modeling function, this paper decided to develop an interface program to transform Midas model data file to DUT2014 model data file. This paper establishes an interface program for converting Midas structured data model file into DUT2014 structured data model file by using Microsoft Visual C++ programming program. In order to verify the correctness of structural data model transformation, this paper will use interface program to transform three different scale structures, and then verify the accuracy of the interface by comparing the quality information, modal calculation results, elastic time history response and elastic-plastic time history response of the model before and after transformation.
