In the nineteenth century, civil and structural engineers received much public acclaim for their built works (e.g. Brooklyn Bridge, Eiffel Tower). One hundred years later, the engineer was perceived by many as "out" or as not requiring much skill. This paper examines how this erroneous perception of structural engineering can change by presenting structural engineers as heroes. Using parallels to the monomythical hero, and examples of engineers, the authors present the journey and characteristics of the structural engineering hero. The journey, which has many paths, begins with the engineer leaving the comfortable "Ordinary World" of design into a "Special World", where new forms, new materials, and/or scale for projects is needed. For underrepresented groups of people such as women and minorities, the heroic journey could be simply becoming an engineer and developing a career in conditions of equality and equity. As structural engineering heroes enter the Special World, they may face trials of nature and criticism, and face constraints of economy, time and knowledge. In the final Act of the journey, they return to the Ordinary World wiser, disseminating their knowledge and inspiring others. The authors define the characteristics of structural engineering heroes by four "P"s: they are prepared, they are planners, they have (super) powers and they are persona grata. The education of the structural engineer should train and inspire future engineers using the lessons learned from the heroes and their diversity. By doing so, what seems exceptional today can become common in the future.

“…For almost forty years, he conducted intense activity as a university professor, researcher, and consultant engineer [3, 17,18]. He was an outstanding designer of new and innovative construction procedures and shapes in thin concrete shells (such as the Zarzuela Hippodrome Roof (1935), see [19]), the Frontón Recoletos (1935), see [20] or the CASA factory roof [21]), structures (the Fedala water storage tank (1956) or the San Nicolas Church in Gandia, see [22]) and bridges (such as Tempul (1926) or Alloz (1947)). To build such remarkable structures, Torroja developed construction technologies, built scale models and monitored his structures to check their safety, learn about their structural behavior, and improve later designs.…”

Modern architecture of civil engineering structures made of reinforced concrete is demanding solutions to problems related to design and construction of roofs shaped as creative forms which require an adequate combination of arts and physical-mathematical models. In that sense, the quadric and cylindrical surfaces offer an attractive based on their volumetric expression, historicity, and mathematical feasibility. In this work, seven cylindrical and quadric surfaces named elliptic cylinder, parabolic cylinder, elliptic cone, elliptic paraboloid, hyperbolic paraboloid, ellipsoid and hyperboloid of two sheets have been analysed to find out which of them show to be more efficient when used as reinforced concrete roof structures. To do so, the configuration of each structure hase been adjusted in terms of similar stiffness, strength parameters and enclosed volume. The structural efficiency was computed using the results of weight/load ratio, available strength, material consumption and relative stiffness. The solution of the model has been achieved using a combination of exact solutions and numerical methods. To compute the model results a Matlab® code was written and validated using the structural software SAP2000®. The best structural efficiency in terms of stiffness, strength, and materials consumption was obtained for roofs configurated using surfaces built from parabolas, i.e., elliptic paraboloid, hyperbolic paraboloid, and parabolic cylinder. The results of this work can be used in future studies and applications related to arhitectural comfort, structural behaviour and material consumption in construction of roofs.
