Course description and aims

This course focuses on the analysis of statically determinate structures with beam, truss, frame and arch members, for which member forces can be determined just by use of equilibrium equations. Then energy principles including the theory of minimum potential energy and the principle of virtual work are explained and applied to the deformation analysis of statically determinate structures in a practical manner. Finally, the reciprocal theorem and influence lines are also explained.

In the course of Mechanics of Materials and Members (CVE.A201), it is shown that the deformation of structures is described in the form of differential equations. In the direct approach based on differential equations, however, the analysis is too complicated for real complex structures. Therefore, this course introduces another method based on energy principle, which provides the solutions for displacement of structures with relative ease. The contents of this course for statically determinate structures will be fundamental for the analysis of indeterminate structures, which will be taught in the following courses of Structural Mechanics II (CVE.A301) and Matrix Methods of Structural Analysis (CVE.A311).

Student learning outcomes

By the end of this course, students will be able to:
1. Determine member forces of various statically determinate structures by use of equilibrium equations.
2. Explain energy principles including the theory of minimum potential energy and the principle of virtual work.
3. Determine member force and displacement of statically determinate structures by means of energy principles.

Keywords

truss, frame structures, arch, statically determinate structure, energy, work, theorem of minimum potential energy, principle of virtual work, reciprocal theorem, influence line

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

This course will be mainly provided in a lecture style. However, students may not obtain enough knowledge and skills on relevant subjects only from lectures. Hence assignments will be given in each class, and answers will be explained for review in the next class.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to references and other course material.

None required.
