Advanced Analysis Software for Steel Frames

Abstract

The manuscript shows an advanced analysis software of steel frames under static loadings. Input and output processes are programed using C++ and FORTRAN. A visual graphic interface for the advanced analysis software is coded for modeling easily and showing the result performance of analyzing structures. The proposed software uses stability functions (SF) to predict the second-order effects on the structures. The plastic hinge approach (PHA) and the fiber plasticity approach (FPA) are integrated in the advanced analysis software. The Generalized Displacement Control Algorithm (GDCA) is utilized for capturing the behavior of frames. A steel 3D frame is analyzed aim to validate the accuracy and time efficiency of developed software.
