Trent Brick Panel : innovative envelope system designed according latest UK national fire and energy performance regulations
No full textIn November 2018, following the Grenfell Tower tragedy in London, the Ministry of
Housing, Communities & Local Government (MHCLG) introduced an amendment to the
Building Regulations 2010, which outlined stricter rules banning the use of combustible
materials defined by the new Building Regulation 7(2). This change had a significant impact
since early 2019, on the materials and systems that can be used in the construction sector. In
2020, the global pandemic caused by the diffusion of the COVID-19 virus represented a new
challenge for the industry, with implications on programme certainty, material procurement,
workforce management, moving towards offsite manufacture. The development of the Trent
Brick Panel is set against this historical and social context. The envelope prototype is the
opportunity for innovation that follows the turn of events. The offsite manufacturing of glassreinforced
concrete panel, mimicking several finishes, is the result of a design investigation
carried out with the market-leading actors: developers, main contractors, subcontractors,
engineering consultancies, architects, local authorities and warranty providers. The research
aims to give an overview of the design principles, sequence and buildability study, assessed
weathering performance according to CWCT Sequence B test and fire performance
Capillary rising damp in Venetian context : state of the art and numerical simulation
Full text linkThe fragility of Venice and its buildings are linked to the floods, observed since
ancient times and emphasized in recent years: the periodic sea level rise, accompanied by rising
damp, are the main causes of the alteration. In particular, the rising damp causes a series of
complex diseases in the historic buildings, such as physical decay, chemical or biological, with
loss of aesthetic and economic value. In addition, greater heat dispersion and reduced thermal
comfort can also occur in interior spaces, with consequent risks for human health. This is a sign
of “Sick Building Syndrome”. It is very important to develop models for assessing the
vulnerability of assets and to manage sustainable plans related to maintenance processes and
activities, satisfying the requirements of effectiveness and compatibility.Basing on numerical
models performed with the WUFI 2D software, the paper analyses the different behavior of rising
damp in relation to materials or masonry structures. In particular, the construction techniques
and typical materials used in Venetian buildings were investigated, such as clay brick walls, lime
plaster, Marmorino and Cocciopesto, adopted mainly to limit the capillary rise also caused by
the phenomenon of “acqua alta”
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
