Streets, squares, and churches in Barcelona
Pons Poblet, Josep Maria; Arboix Alió, Alba
Churches represent an architectural archetype deeply rooted in the urban landscape and in the collective memory of Western society. Even for those who do not frequent them, churches play a fundamental role in the image of the city. Based on a scientific, systematic, deductive, and inductive study of the 132 parish churches in the city of Barcelona, the aim of this article focuses on those cases where the sacred building and its immediate urban environment form an inseparable entity and are placed at the service of the city. The open-air rooms at the foot of some churches are the perfect setting for celebrating all kinds of festivities without having to build new facilities on purpose. Extending this concept of urban reuse, we present some paradigmatic examples of the wise adaptation of the most significant places in the city for holding collective events in the open air. These examples of practicality, which make the most of the available urban enclaves and elements, thus involving all citizens, are excellent examples of the potential use of the city in general and of the spaces outside churches in particular.

Centelles Soler, Xavier; Castro Chicot, Josep Ramon; Cabeza Fabra, Luisa Fernanda
Laminated glass combines glass layers, which provide strength and durability, with transparent polymeric interlayers, which provide coupling between glass layers and prevent glass shards from scattering in case of breakage. The main goal of this paper is to present, through COMSOL Multiphysics simulations, how the mechanical performance (bending stiffness and stress distribution) of laminated glass plates is affected by the shear stiffness of the interlayer material. The simulation results were validated with experimental tests. The laminated glass specimens presented a linear elastic behaviour until glass breakage, and its mechanical performance was affected by the interlayer material selection, as well as the load duration and the working temperature.

Bové Tous, Oriol; Casafont Ribera, Miguel; Bonada Bo, Jordi; López Almansa, Francisco
Unbraced conventional pallet racks are structures intended for the storage of goods (commonly palletized); they are composed of vertical uprights, horizontal beams, and braces, connected together to form a steel skeleton-like structure. Figure 1 displays an isometric view of a pallet rack, highlighting the two directions to be considered in the structural analysis: down-aisle and cross-aisle. The lateral behavior in the cross-aisle direction depends on the shear flexibility and capacity of the upright frames, composed of uprights and braces (Figure 1); single transverse bolts are commonly used to join uprights and framing elements (braces).

The Workshops course as a compulsory subject within the 64 R Plan in the first year of studies at the Barcelona School of Industrial Engineering (ETSEIB) was only part of the curriculum for three years. From that time on, it became an optional subject in the second-year course and there was a decrease in the number of students. A new curriculum, called the 94 Plan, made it an optional subject, with the particularity that it could be taken by students from outside the ETSEIB. In the 1996-1997 academic year, the Workshops (autumn term) and Electrical Workshop (spring term) courses coexisted, the latter being created because the great demand for the Workshops subject could not be met. The last year that the Workshops subject was taught was 1997-1998. From the following year onwards, the subject was renamed Electrical Workshop.
This paper presents the evolution of the Workshops subject and its transformation into the Electrical Workshop course.

En esta comunicación se resume una guía para la evaluación de la vulnerabilidad sísmica de edificios esenciales, elaborada en el marco del proyecto EFA158/16/POCRISC. La guía incluye los antecedentes, los métodos de primer nivel (LM1), el método de segundo nivel (LM2), y el método de nivel avanzado (LMa), que se basa en el análisis dinámico. En el LM1, la acción se define por la intensidad macrosísmica y el edificio mediante índices de vulnerabilidad. En el LM2, la acción se define por el espectro de respuesta y el edificio por su espectro de capacidad y, en el LMa, la acción se define mediante acelerogramas y el edificio mediante modelos estructurales. Para un escenario específico los métodos permiten conocer las probabilidades de que se excedan determinados niveles o estados de daño en función de la severidad de la acción. La guía también aborda aspectos relacionados con la vulnerabilidad funcional y con la fragilidad social, cultural y económica.

Psycharis, Ioannis; Drougkas, Anastasios; Dasiou, Maria Eleni
A numerical study of the behaviour of the walls of the Cella of Parthenon subjected
to seismic loading is presented. Commonly used numerical codes for masonry structures
based on continuum mechanics are unable to handle the behaviour of discontinuous walls of
ancient monuments, in the same way as continuum models cannot capture the behaviour of
drum-columns. In this analysis, the discrete element method was used, which has been proven,
in previous research, capable to accurately predict the response of discontinuous structural
systems. The marble structural stones of the walls were modeled as rigid blocks with fric-
tional joints between them. Two types of models were used in the analyses: (i) a sub-assembly
consisting of only a section of the wall of limited length, either as it is in-situ (partially col-
lapsed) or with its full height (restored) and (ii) considering the whole structure partially re-
stored. In one of the models of type (i), the existing damage of the stones was also
implemented. Analyses were performed with and without considering the metallic elements
(clamps and dowels) that connect adjacent stones

asonry infill in reinforced concrete frames has been recognised as being a strong factor influ-
encing the seismic behaviour of buildings. Therefore, the development of innovative infill systems, coupled
with the rigorous study of their behaviour, is of significant importance. Within the framework of the IN-
SYSME project (http://www.insysme.eu/), a new infill system was designed and tested. The defining feature
of the system, composed of clay units, is the division of the masonry wall into smaller, and thus more flexible,
wallettes separated by vertical joints. The frames are subjected to in-plane cyclic shear loading to the point of
irreversible damage of the masonry. Subsequently, the experiments are simulated using nonlinear finite ele-
ment analysis in an effort to highlight the features of the response of the actual structure, to predict the maxi-
mum force and to reproduce the failure mod

he out-of-plane behaviour of two new systems for infill walls, made of clay masonry units, is
numerically investigated. The two systems were developed within the INSYSME project. In the first system
the enclosure wall is divided into smaller wallettes by means of soft vertical joints, whereas in the second sys-
tem horizontal and vertical reinforcement is provided. In the latter system, a special brick unit, capable of ac-
commodating steel reinforcement and electrical and plumbing installations, was designed. In both systems,
simple sliding connectors are arranged to prevent the out-of-plane collapse of the infills.
An experimental campaign was carried out, involving repeated out-of-plane tests on infilled frames. The walls
were subjected to distributed loads, applied through the use of a specially designed steel frame. Both systems
exhibited significant capacity for load bearing and deformation.

Conservation engineering, as stated by the components of the term, draws from both conser-
vation principles and modern engineering practice in an attempt to balance the demands of both preservation
values and comprehensive structural design. As such, the realities of the building industry and the principles of
conservation practice, when not being hard to reconcile or outright contradictory, leave the structural engineer
with very little room for envisaging and realizing creative and effective intervention proposals. Furthermore,
structural engineers are often sidelined in the decision making process of intervention design, in essence play-
ing but a small role in the strategic planning of architectural conservation projects. The additional constraints
imposed by financial, temporal and administrative limitations generally leave but a narrow spectrum of workable
and realistic choices to structural engineers involved in architectural heritage
