This course has three parts. The first part is concerned with the analysis of statically indeterminate structures by means of superposition of analytical solutions of statically determinate structures or energy principle. The second part gives how to determine plastic limit loads at the failure of structures by use of upper bound theorem and lower bound theorem. The last part focuses on element stiffness equations for truss elements and the direct stiffness method.
In this course, following Structural Mechanics I (CVE.A202), statically indeterminate structures are firstly analysed. It is emphasized that member forces of statically indeterminate structures can be determined by using not only equilibrium equations but also compatibility conditions of structural deformation. Next in the limit analysis called as simple plastic analysis, it is explained that plastic limit loads at the structure failure can be easily obtained using upper and lower bound theorems without taking account of details in failure process. In the direct stiffness method, finally, students learn the basics of matrix structural analysis to solve truss problems.
By completing this course, students will be able to:
1. Determine member forces of statically indeterminate structures, including beam, truss, frame and arch.(S.Hirose)
2. Obtain limit loads at the failure of structures.(S.Hirose)
3. Use global stiffness equations to solve truss problems. (Anil C. W.)
4. Use direct stiffness method to solve truss problems. (Anil C. W.)

Part of each class is devoted to fundamentals and the rest to applications. To allow students to get a good understanding of the course contents and practical applications, problems related to the contents of this course are given in homework assignments. Solutions to homework assignments are reviewed in the class.
