2Frame: Web Software for Application in Non-Linear Geometric Analysis of 2-Dimensional Frames

Resumo

This work presents the development of a web software tool for the linear and nonlinear geometric structural analysis of plane frames. The software leverages matrix methods, specifically the Direct Stiffness Method, and incorporates the Two Circle Iterative Method to account for geometric nonlinearity, alongside principles from solid mechanics. The user-friendly interface allows for easy modeling of frames and input of material parameters, facilitating the determination of stiffness matrices and internal forces. The accuracy and reliability of the software are demonstrated through comparative analysis with data obtained from solved examples in existing literature. Results indicate close agreement, validating the efficacy of the developed tool for nonlinear geometric structural analysis of plane frames. This software stands as a valuable resource for education, research, and professional practice in the field of structural engineering, targeting both undergraduate and graduate students as well as structural professionals in need of nonlinear analysis.
