Large-format thin ceramic panels are increasingly used in ventilated façade systems due
to their reduced weight, high durability and architectural versatility. However, their
reduced thickness and large dimensions require reliable anchoring solutions capable of
safely transferring wind loads to the supporting structure. This study investigates the
structural behaviour of a concealed mechanical anchoring system for large-format porcelain
stoneware panels installed in ventilated façades. An experimental campaign was carried
out using a full-scale façade prototype representative of real construction conditions. The
specimen was subjected to incremental wind pressure and suction loading in a controlled
laboratory environment while monitoring the deformation of the ceramic panels, backing
support layer and aluminium substructure. The experimental results show that the ceramic
panels exhibited stable structural behaviour without cracking or anchor pull-out under
pressure levels up to 3006 Pa, exceeding twice the design service pressure. The maximum
estimated deflection at the service pressure level (1300 Pa) was 5.7 mm, significantly below
the admissible limit defined by the L/200 serviceability criterion. A simplified mechanical
analysis based on classical bending theory confirmed that the stresses induced in the
ceramic panels remained well below their flexural strength. The results demonstrate that
the investigated concealed anchoring system provides reliable structural performance for
large-format thin ceramic panels subjected to wind loading in ventilated façade systems,
while the simplified analytical verification confirms the mechanical consistency between
the measured deformation levels and the flexural capacity of the ceramic material.

UGALDE BLÁZQUEZ, IÑIGO
La persona y la obra de Josep Lluís Sert (Barcelona 1902-83) son ampliamente conocidas. No lo es tanto su aportación a la arquitectura sacra. La historiografía ha reconocido tres proyectos significativos de Sert en este ámbito: la iglesia de Puerto Ordaz (Venezuela, 1951), la capilla de Saint Botolph (Boston, EEUU, 1963-68) y la capilla del Carmel de la Paix (Mazille, Francia, 1967-72). Un estudio reciente, sin embargo, ha logrado identificar una docena de proyectos de arquitectura sacra, desarrollados por Sert a diferentes escalas y niveles de definición, desde el mero encaje urbano hasta la obra construida. En todos ellos se aprecian dos características de la obra de Sert: la planificación de la ciudad y el territorio y la integración de las artes visuales. El punto de vista de Sert sobre la fe católica, con fuerte influencia del teólogo francés Teilhard de Chardin, influirá en su concepción del espacio litúrgico.

After the Spanish Civil War, the shortage of building materials in the country and the
restrictions imposed by the Dirección General de Arquitectura limited the use of steel in
construction, encouraging solutions that reduced the consumption of this material. In this
context, the thin-tile vault gained new relevance due to its low cost, speed of execution
and good structural and fire performance. Among the architects who revisited this system,
Ignasi Bosch Reitg (1910–1985) developed an innovative procedure for the construction of
continuous ceilings, based on double-curved vaults with a single layer of brick. His cousin,
Josep Maria Bosch Aymerich (1917–2015), an industrial engineer and architect trained in
the United States, brought a business vision to the table when he discovered the potential
of this system. This paper proposes an in-depth study of the patents requested on this
system by the two architects, questioning the reasons for their success or failure in different
countries, both in terms of dissemination and exploitation, in regard to the historical context
in which it was developed. The analysis, based on original documents from the Bosch
Aymerich Archive, uncovers the tensions that the reinterpretation and global projection of
a traditional technique can generate.

Casariego Vales, Pedro; Gizatulin, Ravil
Double corrugated cold-formed steel arches, spanning 20–30 meters, are widely used as roofing systems in industrial buildings due to their structural efficiency and ease of on-site fabrication. These structures are manufactured in two steps: first, a steel sheet is cold roll-formed into a straight profile; second, the profile is bent into an arch shape with transverse corrugations. These corrugations affect the effective cross-sectional properties, which cannot be determined using conventional design codes.
Determining the effective area experimentally or numerically is challenging due to the corrugations and the profile curvature. This study examines both effects on the effective cross-sectional area.
The analysis proceeds in two phases: (1) the flat profile, obtained after roll-forming, is evaluated numerically via the Finite Element Method (FEM) and analytically following Eurocode 3; (2) the corrugated profile, formed after the final manufacturing step, is analysed numerically via FEM and analytically using orthotropic plate theory. The results are compared to determine the influence of the corrugations on the strength and behaviour of the original profile.
FEM models are developed using 3D scanning to capture profile geometry before and after corrugation, combined with reverse engineering. The corrugated profile is analysed by FEM in two ways: i) under compressive loads, as commonly used in previous studies and ii) by developing an “idealized” straight corrugated model to accurately apply boundary conditions for pure axial compression and determine the effective area. Comparing both methods provides insight into the profile’s structural behaviour and effective area.
