"Retrofitting design of a two storeys existing building, due to the increased live loads' values, as well as changes in Seismic design requirements. The building has a gross floor area of 2.500m2 and is located in the district  of Hellenic Post Office Sorting Centre ( (Kryoneri Attica - Greece) with a gross area of 35.000m2 ".

Mr Takis Koumoulos (Civil Engineer, NTUA), attended the 23rd Student Conference "On repair and strengthening of concrete structures 2017", which was organized by Professor Stefanos Dritsos (Department of Civil Engineering, School of Engineering - University of Patras), and presented solutions related with "Retrofitting design of a two storeys existing building, due to the increased live loads' values, as well as changes in Seismic design requirements. The building has a gross floor area of 2.500m2 and is located in the district
of Hellenic Post Office Sorting Centre ( (Kryoneri Attica - Greece) with a gross area of 35.000m2 ".
 

Mr. Koumoulos focus on the methods of structural retrofitting and seismic strengthening solutions in the  existing RC building, in order to improve its structural capacity  in the face of seismic events.

In order to increase the structural performance of the existing building,  the retrofitting  and strengthening techniques have been adopted for  all  structural elements and   include column jacketing, adding new columns, retrofitting existing foundation system
as well as adding new foundation elements and connection beams, retrofitting slabs  and application of fibre-reinforced polymer (FRP) sheets.

Used materials :   Concrete   C30/37,    Steel  S500,
                           FRP sheets and shells  made of carbon (CFRP)

Mr Koumoulos made also  reference to the new RC buildings construction ,
in the district of Hellenic Post Office Sorting Centre ( (Kryoneri Attica - Greece),
 with RC frames of 22.80 m spans (area's proportion 10.00 X 22.80 ).

At the same time was made reference to the software Oplismos which creates detailing and precise drawings, proper for the structural detailed designs.
