Greece

Multistory reinforced concrete frame building

This is a typical multi-family residential construction commonly found in suburban areas. It constitutes approximately 30% of the entire housing stock in Greece. Buildings are generally medium-rise, typically four to five stories high. The main lateral load-resisting structure is a dual system, consisting of reinforced concrete beam-column frame and partial shear walls (generally in the form of relatively small-sized reinforced concrete core used as an elevator shaft). The roof and floor structures consist of rigid concrete slabs supported by the beams. Seismic performance of these buildings is generally good, provided that the seismic design requirements are followed, especially to account for soft ground story effects. Failure of the soft ground floor is the most common type of damage for this type of structure. Some buildings of this type were damaged in the 1999 Athens earthquake.

Stone masonry construction

Buildings of this type are mainly found in the historical centers of Greek cities and provinces. The main load-bearing structure consists of stone masonry walls. The walls are built using local field stones and lime mortar. The floors and roof are of timber construction. The seismic performance is generally poor. Diagonal cracking at the horizontal and vertical joints are the common type of damage.

Reinforced concrete frame

This is a typical residential construction found in the suburbs of large Greek cities and in smaller towns. Buildings are three stories with a warehouse on the ground floor level, and typically, two apartments on the upper floor levels. The peculiarity of this building type is that it consists of two independent structures built over different time periods, generally over 20 years. The two lower stories are a reinforced concrete frame structure, without provisions for vertical extension, and the upper stories are added thereafter with some horizontal expansion of floor plan. The entire layout results in a connection of the new and the old structure, however, with added torsional effects under seismic loading. Some buildings of this type were damaged in the 1999 Athens earthquake and were strengthened after the earthquake.
