Description
The only course you will need to learn the direct stiffness method for Beam, 2D Frame, 2D Truss, and 3D Truss linear static analysis.This course aims to introduce and push your understanding further to the direct stiffness method for linear static analysis so that you are ready to go to the next step, which is making your own computer programs to do structural analysis. The course also shows you when and how you can do complex analysis in just a few minutes instead of hours without the help of software and/or programs using hand calculations.In this course, you will learn about these techniques and how and when you can bypass some of the common use and rules to do quick hand calculation checks or to do the entire thing by hand without having to write a piece of computer code.Understanding how structures behave and analyzing complex structures is crucial for competent engineers. This requires knowledge of structural analysis theory and hand-analysis techniques, which form the foundation for intuitive understanding.However, most engineers now rely on structural analysis software for large-scale analyses due to its speed and efficiency. Modern software commonly uses matrix analysis methods like the direct stiffness method to facilitate faster and more complex analyses.the course is divided into 5 sections where you will learn: 3D Truss analysis by hand without any software or programing languageThe essential formulation behind the direct stiffness method.The sign conventions used in the direct stiffness method and even the Finite Element Method.Structural analysis methods and the direct stiffness method.The key stiffness formula for Finite Element Analysis.Formulation of the local and global stiffness matrix of 2D Truss.Transformation of the stiffness matrix Formulation of the local and global stiffness matrix of 2D Frame.Formulation of stiffness matrix using equilibrium of joints.Observation of structures for a quick analysis using the very long procedure of the FEA without the need for computer programs or software packages.This course will prepare you for the next courses where you will learn the direct stiffness method for non-linear static analysis.and use of computer programing languages such as Python in the field of Civil Engineering. The course also has Example and practice problems to make you understand all the concepts to the fullest and also to challenge yourself.
