Concrete Building Constructed In 1933 Before
And After Its Repair

Abstract
The earthquake behaviour of a four-storey reinforced concrete (R/C) building,
which was constructed in 1933, is investigated here, before and after a recent
maintenance and retrofitting. The numerically predicted earthquake behaviour of
the initial structure, under the provisions of the current Greek Seismic Code,
demonstrated the low resistance of this building to the design seismic loads. The
estimate of the strength of existing structural members was based on specific
tests performed in-situ as well as at the Laboratory of Strength of Materials and
Structures, Aristotle University. The retrofitting scheme included the
strengthening of vertical structural elements by jacketing, as well as the use of
carbon fibre reinforced plastics (CFRP) for the improvement of the bearing
capacity of the slabs. The numerically predicted earthquake behaviour of the
retrofitted structure demonstrated the sufficient resistance of the retrofitted
building.
Keywords: retrofitting, old reinforced concrete building, anchorage of CFRP
sheets, improvement of flexural behaviour.
