Course Curriculum CFU Length(h)
[80/71]  ARCHITECTURAL SCIENCE [71/00 - Ord. 2013]  PERCORSO COMUNE 9 112.5

Objectives

The course is designed to provide awareness and basic abilities in the design of steel and concrete structures in architecture. Some basics on conceptual design of concrete and steel buildings are provided.
The design point of view is privileged, but knowledge and technical abilities for site architects are also provided.
The execution of two structural projects of simple buildings with concrete and steel structures is required. Therefore, a design approach toward real design situations is proposed. The execution of working drawings and of the related design report is also required.

Prerequisites

The knowledge of the topics of the course of Mathematics is required.
Also, the basics of Statics and Structural Mechanics provided by the related course of the 2-nd year are furthermore required.
Since the course priviliges a design point of view, the knowledge of the topics of Architectural Technology provided by the related courses of the 1-st and 2-nd years are also required.

Teaching Methods

Lectures in lecture hall.
Exercises in lecture hall and homeworks.
Videos on laboratory tests on materials and structures.

Verification of learning

Written examination divided into two parts, one on steel structures, and the other on concrete structures.
Exercises on the desiign of steel structures and concrete structures are always proposed, but to answer theory questions is also required.
The exam is positively passed with grades between 18/30 and 30/30. Outstanding students can achieve 30/30 con lode (meaning "with distinction").
