Project's Description

The establishment is a 2-story 1200m2 building, constructed in 1958. Its initial use was for boarding school dormitories, while its new use will mainly be teaching rooms. Our scope of work included the on-site structural identification, the analysis and evaluation of the existing building and the analysis and design of the upgraded structure, as well as assistance to the supervision during the construction.

The structural system consists of solid reinforced concrete slabs supported on beams of the same material. The latter transfer the loads either to reinforced concrete columns or, more often, on clay brick or natural stone unit masonry walls.

Factors affecting the analysis were the increased dead and live loads, the higher importance factor, due to the new use, and the low behavior factor, due to the reduced ductility of the existing structure; the last two are used for seismic forces calculation.

The proposed means of seismic upgrade included a rigid diaphragmatic grade slab, single side natural stone wall jackets following grout injections, two-side brick wall jackets, ground floor roof slabs strengthening, selective beam-column joint strengthening, ground floor column sprayed concrete jackets e.t.c.

Main analysis was carried out in ETABS (http://www.csiberkeley.com/products_ETABS.html); slab design was performed using CEDRUS (http://www.cubushellas.gr/EN/03-02-Logismiko.asp)
