“…As suggested by its etymologythe term quincha is derived from the Quechua kencha that means "to close"the technique was originally used to construct primitive huts with frames made of branches and trunks of small trees, which were tied together with vegetal fibres and covered with mud [8].…”

Engineering simulations of a super-complex cultural heritage building: Ica Cathedral in Peru

The Cathedral of Ica, Peru, is one of the four prototype buildings involved in the ongoing Seismic Retrofitting Project, initiative of the Getty Conservation Institute. The complex historical building, which was heavily damaged by earthquakes in 2007 and 2009, can be divided into two substructures: an external masonry envelope and an internal timber frame built by a construction method known as quincha technique. This study makes use of the information available in literature and the results obtained from experimental campaigns performed by Pontificia Universidad Católica del Perú and University of Minho. Nonlinear behaviour of masonry is simulated in the numerical models by considering specified compressive and tensile softening behaviour, while isotropic homogeneous and linear behaviour is adopted for modelling timber with appropriate assumptions on the connections. A single representative bay was initially studied by performing linear elastic analysis and verifying the compliance with the various criteria specified by the applicable normative to discuss the actual failure of Ica Cathedral. Afterwards, the structural behaviour of the two substructures composing the Cathedral is evaluated independently. Finally, the interaction of these two substructures is investigated by performing structural analysis on the entire structure of Ica Cathedral. Several structural analysis techniques, including eigenvalue, nonlinear static and dynamic analyses, are performed in order to: (1) evaluate the dominant mode shapes of the structure; (2) validate the numerical models by reproducing the structural damage observed in-situ; (3) estimate the structural performance; and (4) identify the main failure mechanisms.

“…No hay constancia del empleo en la construcción de las iglesias de soluciones autóctonas locales, tales como quincha 5 o bahareque (14), o de grandes bloques de piedras talladas al estilo incaico 6 en los arranques de los muros (9). Se trata en todos los casos del sistema constructivo español de estructura de fábrica y armadura de madera, sobre el que se han introducido sólo las variaciones puntuales señaladas, que han resultado ser suficientes para mantener la estabilidad de los edificios, con carácter general, durante 5 siglos.…”

En el Altiplano Andino existen en la actualidad centenares de pequeños edificios de estructura de fábrica, inicialmente construidos por la colonización española, que llevan hasta cinco siglos resistiendo terremotos en una de las zonas de mayor peligrosidad sísmica del planeta. La investigación se centra en el estudio de las iglesias de la región de Arica y Parinacota, actualmente perteneciente a Chile. Se trata de pequeñas iglesias de construcción típicamente española (funcional, formal y constructivamente) en las que se han venido introduciendo una serie de modificaciones estructurales clave. La sola constatación de su permanencia, pone de manifiesto que ha sido posible mejorar la vulnerabilidad sísmica de sus estructuras de fábrica. El propósito de este artículo es identificar cuáles han sido las estrategias sísmicas introducidas en América, a partir de un estudio pormenorizado de la geometría, materiales y sistemas estructurales de 30 de estas iglesias, contrastado con la tipología original en España.

“…In contrast, post-Hispanic and modern timber framebased quincha constructions are of interest to many sci-entists, mainly due to their tolerance to seismic phenomena [7], [8] and problems related to the maintenance and conservation of architectural heritage [9]. Simple pre-Hispanic constructions of quincha walls are practically not analysed in terms of strength, and their models are not subjected to experimental strength tests.…”

Interpretation of traces of hypothetical quincha walls in Samaipata

El Fuerte de Samaipata, commonly known as Samaipata, is an archaeological site in Bolivia. It was inscribed on the UNESCO World Heritage List in 1998. The most characteristic feature of the site is a natural rock that served as a wak'a (sacred place) for several local, pre-Hispanic cultures, so its current condition is the result of at least 1200 years of development. Towards the end of the 20 th century and beginning of the 21 st century, Samaipata was comprehensively studied and documented by German scholars. Due to the threat of progressing erosion, a new documentation project was executed by a Polish team. The main objective of the project was to document the vanishing site using 3D laser scanning. Most of the research already published on Samaipata concentrates on the complex arrangement of niches and terraces, figural and geometrical petroglyphs, as well as canals and water reservoirs at the site. The long rows of small circular holes drilled into the rock attract less scholarly attention. They are commonly associated with the vertical posts used for traditional quincha walls. Since there are doubts about the ability of the quincha wall to resist the extremely strong winds on the top of the rock, the Authors conducted computer simulations to clarify these reservations. The 3D model was based on 3D laser scanning results, while FEM was used to solve structural analysis problems.
