“…In the study by Serrano-Lanzarote et al [11], the repair costs obtained for existing systems of this type of joist were approximately 125 EUR/m 2 , reaching 165 EUR/m 2 if it was necessary to increase the element's resistance, with no additional fire protection.…”

“…The main aim of the present study was to investigate the on-site repair of ceramic violin joists [8,9], a field that expanded greatly in the 1940s, 1950s and 1960s on the Mediterranean coast [10], and is without any doubt one of the biggest current challenges in the repair of existing buildings [11]. This type of system [12] was widely used in the post-civil war period in Spain [2,13] in response to the great need for housing combined with real shortages of steel and cement [10].…”

“…This system was applied to an actual case of a building with ceramic violin joist slabs. It is reasonable to expect that many similar structures will require renovation in the near future due to their widespread presence in the existing building stock in Spain [10,11].…”

Due to the present significant need to repair and maintain our buildings and the building repair sector’s minimal experience in special structural elements, we here describe a study on the repair of ceramic violin joist slabs in an actual intervention on a building erected in the 1950s that had been unsuccessfully repaired several times. Due to damp and being close to the sea, the main reinforcement elements had undergone considerable corrosion causing a significant risk to the building’s safety. The intervention necessarily involved replacing the affected steel rebars with appropriate elements with mechanical and corrosion resistance properties, as required by the latest building codes. An appropriate strengthening and repair system was developed with a stainless steel prosthesis fitted to the lower third of the joists that almost tripled their resistance, gave them 120 min of fire resistance, and increased their durability against corrosion at a cost of less than 50% of the current repair systems with minimum generation of construction waste. One of the most appealing characteristics of this new repair system is its avoidance of the full replacement of the joists, which can be considered as a relevant contribution to the sustainability of the construction industry.

Procedure for Safety Assessment and BIM Modelling of an Historical Complex Structure through a Macroelement Approach: The Building “Molino-Pastificio Soresi” of Partinico (Italy)

et al. 2022

The structural assessment of existing historical structures is a complex task due to the inner main difficulty in making up reliable models for structural analysis, able to include mechanical and geometrical nonlinearities, existing damage, complex configurations and arrangements of materials. This task becomes more difficult in mixed RC-masonry structures, which structural modelling can be particularly tough due to the different connections and interactions between structural members and materials. This paper presents the case study of a multi-storey mixed Reinforced Concrete (RC)-masonry historical structure, namely the former mill “Molino-Pastificio Soresi” building, located in Partinico (Sicily—Italy). It is shown as it is possible to obtain an accurate and detailed representation of the building, as well as a reliable structural model. The assessment of the seismic vulnerability from the global point of view of the considered case study is carried out through a multidisciplinary approach based on four stages: (1) historic analysis and study of the relevance of the building; (2) geometrical survey and photographic documentation; (3) structural identification and materials; (4) BIM implementation and structural modelling.
