STRUCTURAL MECHANICS II: THEORY OF TRANSPARENT STRUCTURES
Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course, the student will acquire the theoretical basis and the application tools of equilibrium analysis of structures, such as cables, arches and shells.
Applying knowledge and understanding:
At the end of the course, the student will acquire the ability to understand the static behavior of architecture structures, including cables, arches and shells.
At the end of the course, the student should have acquired a command of the technical language to allow a proper and effective presentation of the results.
Course contents summary
Equilibrium of cables:
Cables under self-weight: parabolic and catenary configurations
Loss of tension due to relaxation
Cable suspended and strayed structures
Equilibrium of arches:
Three hinge arches
Third mean of cross-section
Line of pressure
Method of Mery
Equilibrium of shells:
General: shell of revolution and axisymmetric load conditions
Concepts of surface curvatures
The internal forces in shells of revolution: membrane regime
Equilibrium of uniformly stretched membranes

Teaching material available via the portal lea.unipr.it
The course consists of theoretical lessons and practical exercises. For each topic, exercises are planned so that the student can deal with the resolution of the problems previously formulated in theoretical form.
The theoretical lessons and practical exercises are carried out on the blackboard together with the showing of slides, which are available on the portal lea.unipr.it.
Assessment methods and criteria
The assessment of student learning is formulated on the basis of a final written exam.
The final exam is weighted as follows:
- 70% application of the theory to exercises (applying knowledge and understanding);
- 20% theoretical questions (knowledge and understanding);
- 10% clarity of presentation (communication skills).
It is strongly recommended to attend lessons.
