The Arganzuela Footbridge is a helicoconical spatial truss consisting of two single-span bodies spanning 117 and 96 m over the Manzanares River and the Arganzuela Park in Madrid, Spain. It connects two residential neighborhoods and provides access to the park for both pedestrians and cyclists. The innovative main structure of both the bodies is a conical spatial steel truss of circular section, with curved diagonals and straight longitudinal chords, all of them inscribed in two tronco-conical surfaces. The diagonals run along four helixes, which may be grouped into two families of contrary directions. The geometrical arrangement thus generated responds to the architect's aesthetic purpose. This configuration determines the structure of the footbridge bodies that-although have an adequate overall depth in relation to the span and, being a truss, a favorable structural type for a longitudinal structure, lose part of this favorable disposition due to the curving of the diagonals, which introduce undesirable bending stresses in the diagonals. In addition to the unusual shape and dimensions, the foundation is very complex and is greatly conditioned by the existence of underground motorway tunnels and sewers. © 2014 Publishing Technology.

In this society, ever so technological and under permanent development, tall buildings offer the most favorable solution against the new demands and challenges that this development gives rise to. Under these circumstances it is necessary to establish a criterion for the evaluation of tall buildings, not based on mere height but on coherence, quality and adequateness, terms which embrace the holistic efficiency of a tall building. Coupled with this efficiency comes into play the concept of proficiency, defined as the generic accomplishing capacity in all the disciplines involved in the design, construction and management of tall buildings. It is considered that the current proficiency of knowledge allows designs of great holistic efficiency -endowed with maximum coherence, quality and adequateness- in the range of tall buildings under 300 m. Above these heights -and in many cases, below-efficiency drops. Despite this, supertall and megatall buildings, which are usually promoted by a desire of projecting an image by an individual rather than by a direct need of Society, have a positive outcome as they serve as driving forces of knowledge. This position consequently requires a new reflection, which must start from an introspection into the responsibility in the architectural/structural fields, and reach an essential review of the profound ideas of form and structure, leading to a return of excellence.
