QEEE D2S Session on
"Matrix Stiffness Method"
21st, 22nd and 23rd August, 2017
QEEE session on Matrix Stiffness Method - Structural Analysis was conducted by Prof. Sushanta Chakraborty, IIT Kharagpur under D2S Program on 21st, 22nd and 23rd August, 2017. It was locally coordinated at Dronacharya Group of Institutions, Greater Noida by Local Faculty Coordinator Mr. Navdeep Agrawal, Assistant Professor-Civil Engineering.
SESSION 1: 21st August 2017
Prof. Sushanta Chakraborty started his lecture with a brief explanation of what is the importance of Structural Analysis in civil engineering and also discussed the grounds on which a civil engineer has to work and analyses under different conditions by using Matrix Stiffness Method. He covered the following topics during the session:
- Static and Kinematic Indeterminacy
- Force (Flexibility) and Displacement (Stiffness) Methods
- Fundamental differences between the flexibility and stiffness approach.
- Analysis of plane trusses using stiffness approach
SESSION 2: 22nd August 2017
Prof. Sushanta Chakraborty started his lecture with the kinematic and static indeterminacy of plane frames and gradually progressed to direct stiffness approach for plane frames. The direct stiffness method for continuous beams and plane frames were discussed. He also discussed about the kinetic indeterminacy in continuous beams, Slope-deflection relationship of beams and intermediate loading.
Later he discussed kinetic indeterminacy of plane frames. Prof. Chakraborty explained Element Stiffness Matrix and how to transform it into Global Matrix. The procedure to convert plane frame to 3-D or space frames was also discussed.
SESSION 3: 23rd August 2017
Prof. Sushanta Chakraborty started the third session with the introduction to Finite Element Method. He also explained simple example of a Cube and represented various stress and train acting on cube element in the matrix form. The process of FEM was started with domain discretization (dividing structure into elements), connected at nodes followed by approximately ‘expressing’ the field variables e.g. displacement, in terms of nodal displacements and the shape functions.
The session covered important methods of Flexibility and stiffness. This helped in understanding of conceptual as well as practical implication of the Structural Analysis in Civil Engineering.
The proctored assignment and quiz is to be submitted by the students through their QEEE account on or before 11h September 2017.
