MAIN PROJECTS

PROJECT 1 STATIC , DYNAMIC ANALYSIS AND STRENGTHENING OF AN EXISTING

4-STOREY BUILDING IN VIRONAS , ATHENS , GREECE

Client: Building owner

Structural design: Aristidis Karanikolaou, Civil Engineer

Vasiliki Siormpa, Civil Engineer (MSc)

Description of the project: The existing building has a 1.360,00 m2 total coverage

and consists of one underground floor, ground floor, 1st, 2nd, 3rd floor and roof

floor. The existing building has been designed in 1998 according to that time

current standards. An additional storey made of steel beams will be added

between the ground floor and the 1st floor.

Current status: The building operates as a social care center, the ground floor will

be converted into a supermarket and an additional storey will be built at +3.20

m. This storey will be seated on the existing concrete structure via main HEB 140

and ancillary IPE 100 metallic girders.

Strengthening methods: Structural analysis and strengthening study have been

performed according to the current Greek Standards. Due to the loads of the

additional storey and the insufficient stiffness along the transverse direction of

the building, strengthening with a jacket of reinforced concrete is suggested in a

shear wall along the transverse direction.

Design period: November 2014-January 2015

ISLAND OF LIMNOS, GREECE

Client: Ag. Georgios Church, Atsiki, Limnos

Architectural design: Evangelos Kounenis, Architect


Grigorios Tsirikos, Civil Engineer

Description of the project: The belltower of the Church of Ag. Georgios is a 3-

storey (ground, first and second floor) existing stone structure with reinforced

concrete slabs and dome, built in 1928. The structure is 17,60 m high and has a

6,00 m x 6,00 m surface coverage. Corrosion of the steel load-bearing elements

is the main structural defect.

Restoration and strengthening methods: Removal of the first and second floor

slabs (reinforced concrete between steel sections) using undisturbed cutting

methods and replacement with new ones with concrete and stainless bars.

Homogenization and strengthening of the masonry walls. Due to the corrosion of

the steel bars of the dome , the existing dome is removed with undisturbed

cutting methods and a new dome with stainless frames is constructed with the

equal shape as the origin.

PROJECT 11 DETAILED DESIGN OF THE HISTORICAL FOLKLORE MUSEUM OF

LYCEUM OF GREEK WOMEN IN ERMOUPOLIS, ISLAND OF SIROS, GREECE

Client: Municipality of Ermoupolis

Architectural design: Ioannis Batas, Architect

Aspasia Dimaki , Architect


Nikolaos Sotiropoulos, Civil Engineer

Description of the project: The existing main building (215,00 m2 of plan surface)

consists of underground floor, ground floor, first floor and wooden roof. On the

north view of the building there is a “loggia”, with load bearing marble members.

Main Pathology: Cracks in the load bearing masonry, insufficient cross sections in

the members of the wooden roof and the wooden floor beams, corrosion of the

metal bars , which connect the marble sections of the loggia’s columns.

Restoration and strengthening methods: Homogenization, single-sided

strengthening of the masonry walls. Replacement of the existing wooden roof

with a new one. Strengthening of the wooden floor beams with steel plates.

Gradual degradation of the loggia’s marble parts and extraction of the oxidized

metal bars. Repair or replacement of the marble sections . Replacement of the

PROJECT 13 STATIC AND DYNAMIC ANALYSIS, STRENGTHENING FOR AN EXISTING

SECONDARY SCHOOL AND A HIGH SCHOOL IN LIMNI , ISLAND OF EUBOEA , GREECE

Client: Prefectural Local Government of Euboea , Greece



Maria Papadopoulou, Civil Engineer

Geotechnical design: Ilias Sotiropoulos, Civil Engineer

Description of the project: The main building consists of four levels (A, B, C, D)

with external dimensions 51,60 m x 29,10 m and 12,65 m height between the

ground of level A and the roof of level D.

Main Pathology: A part of the building has settlements and cracks. Geotechnical

research has been proposed to the Prefecture, due to the foundation being placed

above a large slope. The drillings showed fill material of large thickness (4,50 m -

15,00 m) under the surface of the foundation.

Restoration and strengthening methods: Restoration and strengthening studies

suggest a solution with micro-piles, in order to transfer the loads into the safe

ground under the fills. Micro-Piles of 25 cm diameter are infixed in a 3.0 m depth

inside the safe ground under the fills. The whole strengthening of the foundation

is combined with reinforced beams and foundation slab.

Design period: July 2001-December 2002

PROJECT 14 STATIC AND DYNAMIC ANALYSIS, STRENGTHENING FOR THE

NATIONAL THEATER OF ATHENS, GREECE

Client: Board of directors of the National Theater of Athens, Greece

Architectural design: Ioannis Batas, Architect



Christina Maragkaki, Civil Engineer

Geotechnical design: Ilias Sotiropoulos, Civil Engineer

Description of the project: The National Theater, originally designed by Architect

Ernst Ziller (1891-1901), is a listed building. The vertical structure of the Theater

consists mainly of masonry and reinforced concrete. Small masonry vaults

supported on steel sections and concrete elements form the floors of the building.

Main Pathology: The main defects of the structure had been located on the north

side of the building, resulted by the former extraction of high walls behind the

Central Stage and on the masonries of the upper floors which had been cracked

due to tensile stresses.

Restoration and strengthening methods: Homogenization, single-sided

strengthening of the listed masonry walls.

Design period: August 2001-December 2001
