Strengthening of Football Stadium in Serres

18th Conference on Concrete, Athens
March 29-31, 2018
The loading capacity assessment of the R/C structural system of the football stadium – south section in Serres is carried out and a strengthening intervention of its performance is proposed using steel profile encasements. The quality control, verified by sampling and testing, has shown not acceptable concrete strength, lower than C8/10, and too large concrete carbonation depth …

Design of High Performance Concrete Structural Elements under Bending and Shear

15th Conference for Concrete, Alexandroupolis
October 25-27, 2006
High Performance Concrete has seen extensive and successful use in many countries over the last decade. In Greece, the first steps towards the production of High Performance Concrete have been undertaken by the company AGET-Herakles, through a research project co-funded by the greek GSRT (General Secretariat of Research and Technology), AGET-Herakles and Cubus Hellas, and executed in cooperation with the University of Thessaly’s Civil Engineering faculty …

High-Performance Fiber-Reinforced Concrete – Application to New Structures or the Seismic Strengthening of Existing Ones

15thConference for Concrete, Alexandroupolis
October 25-27, 2006
In this project, we give examples for the application of high-performance fiber-reinforced concrete in the following cases: a) In new constructions: composite slabs, precast prestressed beams, construction of slender columns b) In the strengthening of existing structures: Increasing the ductility of an existing column through a jacket …

A Method for the Pre-Seismic Checking of Pilotis Columns

2nd Hellenic Conference for Seismic Engineering and Seismology, Thessaloniki
October 28-30, 2001
A simplified method for the preseismic evaluation of pilotis columns is proposed. The method considers the soft story mechanism and is based on elastoplastic analysis by use of the push over method. The Displacement Coefficient method (DCM) is applied and the plastic rotation and shear transfer in the columns are examined according to the latest scientific knowledge. Finally, measures for improvement of the behaviour and strengthening are proposed.

Reliability of the Displacement Coefficient for Simplified Non-Linear Calculation of Structures

2nd Hellenic Conference for Seismic Engineering and Seismology, Thessaloniki
October 28-30, 2001
In this paper the reliability of the Displacement Coefficient method (DCM) for the assessment of the response of structures under seismic action is examined. The approach is based on the dynamic time history analysis of single-degree-of-freedom (SDOF) structures under several Greek ground motion records. The results of these analyses are compared against those obtained with the DCM

The Push Over Method

Seminar of the Technical Chamber of Cyprus, Nicosia
June 2, 2001
In our earthquake resistant design our aim is to improve the mechanic behavior of the structure. This improvement mainly concerns three areas: – Reduction of total deformations (elastic and mainly inelastic) – Reduction of the inertial forces that develop in the structure during the earthquake – Absorption of energy by plastic deformation (or damping in general) without risk of failure of the members of the structure

Repair / Strengthening of Buildings by means of Additional Shear Walls and Cores

International Scientific Meeting Istanbul 11 and 12 January 2001, two-day Conference jointly organized by TCG (Technical Chamber of Greece) and Turkish Chamber of Civil Engineers
Athens, January 8-9, Istanbul, January 11-12, 2001
One of the most efficient methods of strengthening of buildings against earthquakes, is the addition of walls or cores. Its advantages are that the possibility of collapse is completely averted, as horizontal loads are transferred to the newer, stronger elements, while the deformation and damage of its load-bearing and non load-bearing elements is minimized …

Ductility and Fracture Models of Reinforced Concrete – Applications

Kavala, 1987, Reinforced Concrete Conference
It is now a common perception that the safety of a structure against collapse is directly related to its behavior in the range of inelastic deformations ……… ..the most important one for our country, is able to undertake imposed dynamic loading, such as earthquake and impact, much higher than predicted by a strictly elastic analysis
