Characterisation of Portuguese RC Precast Industrial Building Stock

Abstract

The construction of a vulnerability model requires reliable information on the features of the buildings in the study. The purpose of this work is the characterisation of the precast industrial buildings in Portuguese industrial park, based on the survey of 73 design projects of existing buildings. The collected data are based on a previous study on the features that influence the seismic response of this type of buildings. The parameters collected are associated with the global geometry and specific elements characteristics (e.g., column dimensions, reinforcement ratios, and connections details), to the mechanical properties of the materials and other parameters that can give some important information in the characterisation of the buildings (e.g., construction year and localization). In the end, a comparison with other available databases, namely, from Italy and Turkey, is done in order to conclude about the similarity. This information is important to define representative experimental specimens and numerical simulation to conduce seismic risk analysis.

Seismic fragility functions for Portuguese RC precast buildings

“…However, this information is insufficient and does not provide detailed data regarding the mechanical, geometric and dynamic properties of the industrial buildings, required to develop representative numerical models. Alternatively, the geometric and mechanical parameters of the Portuguese industrial RC precast buildings collected by Rodrigues et al (2020) allowed the definition of reliable numerical models that can be used to generate a synthetic model and derive analytical fragility functions. This paper explores also the consideration of both local and global limit states exposing the current limitations regarding the definition of suitable structural limit states for RC precast columns (e.g., Erberik 2008;Crowley et al 2004).…”

Cyclic behaviour of precast beam‐to‐column connections with low seismic detailing

“…The detail of the specimens was established through the work of the typical properties of Portuguese precast industrial buildings presented by Rodrigues et al, 11 namely the column dimensions, corbel length and detail, concrete compressive strength, longitudinal and transverse reinforcement grade, connections dowels, that is, the number and the diameter, to represent a beam-to-column connection of a typical Portuguese industrial precast building, illustrated in Figure 1 in red. A total of 12 tests were performed.…”

“…After the literature review and considering the specific properties of the industrial building stock, [11][12][13][14] it was noticed that there was a lack of study of the connections without any mechanical device, named as pure friction connections and, since it will be studying the connections that typically reflect the connections found throughout Europe, also the dowel connections will be studied, as described in the next section.…”

Assessment of the Seismic Behavior of a Precast Reinforced Concrete Industrial Building with the Presence of Horizontal Cladding Panels

“…Precast reinforced concrete industrial buildings are structures with significantly more flexibility when compared with traditional RC residential building, due to the higher story height (in Portugal the typically story height is between 6 and 8 m [11]) and the column boundary condition, usually materialized through cantilever columns fixed at the base with prestressed beams with hinged connections between these two elements.…”

“…The current design practice for industrial PRC buildings is based on bare-frame models and the cladding-panel contribution is generally neglected; therefore, no interaction between the panels and the structure is considered [1]. Furthermore, it was observed in a recent survey carried out on Portuguese PRC buildings [11] that cladding panels, both in old and recent buildings, are generally not considered in the design, not even with simplified procedures, ignoring the interaction with the frame and it is considered that they do not contribute to seismic behavior. Several authors, however, have demonstrated that cladding panels can have a significant contribution to the seismic response [1,4,[12][13][14][15][16].…”
