Article
Full-text available
The influence of cladding panels on the seismic behaviour of precast structures has for a long time been neglected, on the grounds that they were intended as non-structural elements and, as such, not expected to affect the global behaviour of the buildings. Increasing evidence from past earthquakes led to the conclusion that those assumptions did n...
Article
The EU has to drastically accelerate the clean energy transition and increase Europe's energy independence from fossil fuels – and from Russia. This focus is not new: decarbonisation of industry is a key element on the EU’s path to achieving the objective of climate neutrality by 2050 and an intermediate target of reducing greenhouse gas emissions...
Article
Full-text available
In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of the slab around the column (punching failure) is typically the governing failure mode which limits the deformation capacity and can potentially lead to a progressive collapse of the structure. Existing rules to predict the capacity of flat slab f...
Article
Full-scale testing of a two-storey flat slab structure is reported, undertaken in the SlabSTRESS research project; the construction and testing were planned and carried out at the ELSA laboratory of the European Commission's Joint Research Centre. The dimensions are three bays by two, spans 4.5 and 5 m, slab thickness 0.2 m, interstorey height 3.2...
Article
Full-text available
New precast frame industrial structures are seismically designed according to reliable modern criteria. However, most of the existing built stock hosting many workers and both regular and strategic industrial activities was designed and detailed neglecting the earthquake load or according to outdated seismic design criteria and regulations. Its sei...

Full-text available
The SlabSTRESS project investigated the behaviour of a full-scale Reinforced Concrete flat slab building under both gravity loads and seismic lateral actions. The two-storey structure had 9.0 m × 14.5 m plan dimensions, three bays in the loading direction and two orthogonally. This layout enabled to test simultaneously three types of slab-column co...

Conference Paper
Full-text available
Flat slab buildings for commercial, office and residential use are built in many countries. Yet, their behaviour under seismic and gravity actions is still not very well understood. Many studies have been carried out in North America but European research is lagging behind and currently Eurocode 8 does not cover the design of buildings with flat sl...

The EQUFIRE project aims to study the post-earthquake fire performance of steel frame structures and is part of the Transnational Access activities of the SERA project (www.sera-eu.org) at the ELSA Reaction Wall of the European Commission-Joint Research Centre. As it has happened in many historical occasions, after an earthquake, earthquake-induced...
Patent

Article
Full-text available
The construction industry, as a main energy consumer and a foremost contributor to greenhouse gas emissions, has been undergoing a “green revolution” in the recent years. Sustainability has become a prominent issue, and environmental methods such as footprint schemes and Life Cycle Analysis approaches are being considered in the design and in the r...
Article
Full-text available
The traditional seismic design of precast frame buildings concerns the calculation of the frame, considering the cladding panels as non-structural added masses without stiffness, assuming they are connected so to not interact with the frame. Under seismic excitation, the cladding connections are subjected to complex multi-directional actions, depen...
Conference Paper
The present study moves from the awareness about the structural condition of the European building stock, which, in some cases, is far from the level of structural safety required by the European codes. Where the seismic risk is more relevant, as in southern Europe, the adaptation of building heritage according to modern seismic standards must be p...
Conference Paper
Current design approaches ignore the influence of cladding panels, assuming that they are non-structural elements not interacting with the frame. Unfortunately, the detailing of panel-to-frame connections may give rise to major safety issues in case of earthquake. The SAFECLADDING Project was aimed at assessing current systems and proposing new sol...
Article
Full-text available
The design of new buildings, and even more the rehabilitation of existing ones, needs to satisfy modern criteria in terms of energy efficiency and environmental performance, within the context of adequate safety requirements. Tackling all these needs at the same time is cumbersome, as demonstrated by several experiences during recent earthquakes, w...

Full-text available
The alarming data on world climatic change, resources impoverishment and increasing human diseases caused by environmental pollution has encouraged the modern society to feel committed in reducing the environmental issues and to adopt a sustainable approach to every human activity. Sustainability is an ambitious challenge for Europe development and...
Article
Full-text available
New building materials and techniques are increasingly developed to respond to the challenges posed by the need of reducing energy demand of buildings while keeping adequate answer to housing needs. The potential of Cement Based Composites (CBCs) panels in which a large amount Phase Change Materials (PCMs) is embedded have been explored in this stu...
Article
Full-text available
Steel angles are extensively used to connect concrete floor/roof elements to the supporting beam in typical dry-assembled precast frame structures widely diffused in Europe and other parts of the world. These connections allow for relative rotations of the floor element in its vertical plane and restrain their relative displacement, avoiding possib...
Article
Full-text available
The use of phase change materials (PCMs) in building elements has gained increasing popularity in recent years because of the potential energy savings that result from the heat stored during variable temperature–time histories. This paper describes the results of non-linear numerical analyses on sandwich panels characterized by different geometry a...
Article
Full-text available
Silicone sealant is usually interposed between panels of precast façades. In ordinary cladding panel configurations, relative sliding between panels occurs under lateral actions. The shear drifts and consequent stresses arising in the silicone strips may lead to a significant increase of the load demand in the cladding panel connections and affect...
Article

The SAFECLADDING Project was aimed at improving the connection systems between cladding panels and precast RC buildings in seismic-prone areas. Three design criteria have been assessed: isostatic, dissipative and integrated. They can be realised using different strategies, which are represented by several test setups within the experimental campaig...

The global population now exceeds seven billion. This means that during the past 250 years or so, it has increased tenfold that of the Industrial Revolution in the mid-18th century, which is believed to have been 700 million. Eighty percent of the global population lives in developing regions, which means that the consumption of resources and energ...
Article
Full-text available
Dry-assembled precast concrete frame structures are typically made with dowel beam-to-column connections, which allow relative rotation along the beam direction. In the orthogonal direction the rotation of the beam is prevented but again the connections of the superimposed floor elements allow for relative rotation. All the ductility and energy dis...

Four years ago, a precast industrial building collapsed due to the failure of a pre-stressed beam.
