Learning from failures in an emblematic building in Valencia, Spain

Abstract

On many occasions advances have been made in science and engineering thanks to the knowledge gained from failures. In the particular case of structural engineering the study of actual failures makes it possible to advance and define new theories, concepts and designs, for example, the changes and improvements that appeared after some of the "classical" failures such as the Ronan Point building, Quebec Bridge, Murrah Federal Building, Tacoma Narrows Bridge and the World Trade Center. This paper describes a teaching method used with structural engineering students at the Universitat Politècnica de València based on the study of cases of damage to buildings in the Valencia, Spain. Due to its special characteristics, one of the buildings studied is the Príncipe Felipe Science Museum. Some of its main characteristics are: 1) it is one of Valencia's emblematic buildings, 2) its considerable dimensions required huge quantities of concrete, 3) it has a complex structure and an innovative architectural design, 4) the wide variation in the type of damage detected, which make it a particularly valuable teaching aid. The most important damage detected has been classified and described during the visits to the Príncipe Felipe Science Museum. The damage mechanisms are widely diverse and include: those due to the behaviour of the concrete itself (e.g. shrinkage and early age thermal cracking), those due to the presence of damp, those whose origin can be traced back to the construction phase, and others due to corroded reinforcement and to the loads acting on the structure. The paper has a double value since on one hand it describes a highly successful teaching aid for the training of specialists 2 in structural engineering, while on the other it classifies and describes the existing damage in one of the most important modern buildings in Spain and perhaps in Europe.

When ‘less is more’: The rationale for an adaptive toolbox to manage the risk and uncertainty of rework

“…Rework arising as a consequence of an action error, violation, or error in judgment and decision-making can have far more reaching consequences for construction organisations than those that occur from scope and change orders, providing the "raw material for tragic events and catastrophes" (Frese and Keith, 2015: p.663). Examples of errors in engineering design abound, with many going unidentified until emerging as failures during the construction and operation of an asset (Adam and Buitrago, 2018;Blaszcynski and Sielicki, 2019). In addition to the Mascot and Opal Towers identified above, the Champlain Towers South Condominium (Miami, Florida) is a pertinent high-profile example, where a design error went unidentified for 28 years before tragically resulting in the building collapsing, killing 98 people (BBC, 2021).…”

Antimicrobial concrete for smart and durable infrastructures: A review

“…If the infrastructures such as hospitals and sewage systems have the ability to kill viruses, it is beneficial for preventing the spread and reproduction of viruses. Furthermore, the combination of new technologies may promote the development of antimicrobial concrete, such as nanotechnology, geopolymer technology, 3D printing/digital production technology, biotechnology, self-assembly technology, damage and failure evaluation technology, organic–inorganic composite technology and multiscale simulation technology [89] , [90] , [91] , [92] , [93] , [94] , [95] , [96] , [97] , [98] , [99] , [100] .…”

Identification of Building Failure Indicators

“…[3]. Building failure is defined as a human act, or omission of occurrence or performance, lack of success, nonperformance, insufficiency, loss of strength, and cessation of proper functioning or performance [1,4,5]. Obviously, a building must be structurally safe, and the floors must be capable of resisting any normally imposed loads [4,6].…”
