Introduction




Scienza delle costruzioni is a branch of applied physics and engineering that deals with the construction and analysis of physical and mathematical models that describe the static and dynamic behavior of the structural components of a construction under various actions or stresses (external forces, thermal variations, seismic events, etc.). As such, its main purpose is to develop an operational mindset that leads to recognize, formulate, and solve problems of structural resistance.


It is an applied science that has its roots in classical mechanics. It is a science because it proceeds by assuming theoretical models of behavior, based on hypotheses that are as simple and logically consistent as possible, and it explicates and discusses their consequences. It is an applied science because it applies to the modeling of the load-bearing structures of real constructions, and the set of its theoretical constructs is judged not based on their formal elegance, but based on their efficiency as a support and criterion for design choices.


What is scienza delle costruzioni?




Scienza delle costruzioni is composed of a set of different disciplines of physical-mathematical (analytical mechanics, elasticity theory, continuum mechanics), experimental (materials science), and also computational and numerical (computational mechanics, automatic calculation of structures) character. In fact, in the Anglo-Saxon tradition, there is no subject 'scienza delle costruzioni' and its contents are generally divided into university courses of strength of materials, structural mechanics, and continuum mechanics.


Scienza delle costruzioni is the basic discipline of structural engineering, a relevant subject of civil engineering, building engineering, mechanical engineering, architecture, aerospace engineering, and naval engineering. As such, the courses of study of Scienza delle Costruzioni are the basic training for many degree courses of the Faculties of Engineering and Architecture.


How did it develop over time?




The origins of scienza delle costruzioni can be traced back to ancient times, when humans started to build structures such as bridges, Continuing the article: temples, pyramids, and other monumental works. They used empirical methods and simple tools to test and adjust their designs, relying on intuition and experience rather than rigorous calculations. Some of the earliest known civil engineers were Imhotep, who built the step pyramid for Pharaoh Djoser in Egypt around 2700 BC, and Archimedes, who applied the principles of levers, hydrostatics, and mechanics to various problems in ancient Greece. The development of scienza delle costruzioni accelerated during the Renaissance, when many artists and architects such as Leonardo da Vinci, Galileo Galilei, and Andrea Palladio studied the statics and dynamics of structures and materials. They applied geometric and algebraic methods to analyze the equilibrium and stability of beams, arches, domes, and trusses. They also experimented with different materials and shapes to test their strength and elasticity. The modern era of scienza delle costruzioni began in the 17th century with the emergence of analytical mechanics and the calculus. Isaac Newton, Robert Hooke, Leonhard Euler, Daniel Bernoulli, and others formulated the laws of motion, the theory of elasticity, the Euler-Bernoulli beam equation, and other fundamental concepts that are still used today. They also introduced the use of differential equations, variational principles, and matrix methods to solve complex problems of structural mechanics. The 18th and 19th centuries witnessed a rapid growth of scienza delle costruzioni due to the Industrial Revolution and the development of new materials such as iron, steel, concrete, and reinforced concrete. Engineers such as Thomas Telford, Isambard Kingdom Brunel, Gustave Eiffel, Robert Maillart, and others designed and built remarkable structures such as bridges, railways, towers, dams, and skyscrapers that pushed the limits of engineering knowledge and practice. They also developed new methods of analysis and design such as graphical statics, plastic theory, limit analysis, and prestressed concrete. The 20th and 21st centuries have seen further advances in scienza delle costruzioni with the advent of new technologies such as computers, software, sensors, robotics, Continuing the article: and artificial intelligence. These technologies have enabled engineers to design and analyze more complex and innovative structures, such as cable-stayed bridges, high-rise buildings, space stations, and nanomaterials. They have also improved the accuracy and efficiency of structural modeling, simulation, testing, and optimization. Moreover, they have facilitated the integration and collaboration of different disciplines and stakeholders involved in the structural engineering process.
