The use of physics in structural engineering requires the combination of its logical strength with social sensitivity. Logical strength is provided by mathematics and physics with practical solutions and new thinking relationships. Social sensitivity is achieved by inserting this "hard" knowledge into the solution of community problems. It is desirable that the teaching of physics and its applications prioritize holistic knowledge over mechanicity and that this process be similar to the one followed by the artist when he conceives his work: he dreams it, tries it, feels it, and adjusts and delivers it after having understood it with his whole being. In terms of curriculum, it is advisable to rethink the contents, encourage the use of majeutics, reduce standardization, personalize evaluation, and abolish the belief that there can be useless knowledge.

Physical – mathematical model to determine the structural efficiency of sections shaped as ellipses and parallelograms when used in reinforced concrete columns

Current practice of structural design of reinforced concrete columns uses mainly rectangular and circular sections. Among other reasons, this preference is linked to its ease of construction and spatial efficiency, and the historical inertia of civil works processes. Nowadays, modern design and construction techniques make possible to study the structural beahviour of sections distinctively shaped. If typical sections are extended from circular to elliptical and from rectangular to parallelogram shaped, it is possible to compute mathematical and physical parameters needed for the structural analysis. This work presents a physical–mathematical model to determine the structural efficiency in terms of relative strength and stiffness of sections shaped as ellipses and parallelograms when used in reinforced concrete columns. To solve the model, a Matlab® code for drawing the column interaction diagram of each studied section was written. Each diagram describes, in terms of mechanical physics, the relation between the uniaxial bending and the compression load that defines safety conditions as a mathematical limiting curve. The governing equation has the form P(m, g)=f(M(m, g) in which P describes the axial load strength function, M the bending moment strength function, m the material properties, and g the geometrical characteristics function. Structural efficiency has been expressed as the relative behaviour of each section with respect to comparable rectangular sections. To obtain the results of the model, a Matlab® code was written.
