Objectives

Once completed the course, the students will be able to: (i) classify truss and beam structures; (ii) formulate and solve equilibrium problems both in direct form and through the use od the Principle of Virtual Works; (iii) compute and represent the internal forces in beams and truss structures.

Contents

Basic problems of Mechanics relevant to structures composed by beam and truss elements. The kinematics and statics of rigid bodies assembly are studied. The supports reactions and the internal forces of statically determined structures are computed

Teaching Methods

The study is organised in theoretical lessons and exercises. A practical experience is performed by the use of a physical model of a truss structure .for which the theoretical collapse load is estimated and checked against the results of loading tests

Evaluation methods

Verification of learning:

The exam is composed by a written test and a speaking test.
Those who pass the written test gain access to the speaking test.
The speaking test is taken one week after the written test.
Tow intermediated checks are foreseen plus a final check at the end of the course

Contacts/More Information

Attendance is recommended, but not mandatory. The attendance is monitored randomly.
