ENHANCED TECHNIQUES FOR UNDERSTANDING PORTLAND CEMENT CONCRETE PAVEMENT BEHAVIOR. FINAL REPORT

The FEACONS V AND INPLANE II programs have been combined into a single program called COMBO. Systematic and formal software engineering techniques have made COMBO more efficient and easier to expand. The size of the executable file of COMBO has been reduced by 50% and the execution time is 30% faster using the COMBO program. COMBO uses dynamic storage for mesh-dependent size arrays which allows any size mesh to be analyzed without changing the program. Plate bending displacements produced by a FEACONS analysis are saved in memory and can be directly transferred to be used in an INPLANE analysis in the same run of COMBO. Plate bending displacements can also be saved in files to be used in an INPLANE in future runs of COMBO. The plot program CPLOT was developed to allow post processing of the results from a FEACONS analysis. CPLOT runs on an MS-DOS microcomputer. COMBO runs on a minicomputer. COMBO produces a database file for CPLOT that must be transferred from the minicomputer to the microcomputer. CPLOT plots deflected shapes, deflection contours, and principal stress contours superimposed on the un-deflected model of the slabs. Other graphics capabilities include changing the viewing direction, choosing load conditions, and windowing.
