Earthquake Missions’’
were served byTassios as early as
1963 (Skopje) and1966 (Iran), incollaboration with N.
Ambraseys. He also
participated in theUNIDO regional
earthquake mitigation
project in the BalkanCountries (19821983)

Tassios founded (1969) the Laboratory of R.C. and Masonry
Structures at the NTUA, specialized in seismic behaviour ofstructural elements.

The main analytical research topic of Tassios’ Group
concerned modeling of structural elements’ behavior underimposed cyclic post-yield deformations, based only on firstprinciples. Thus, i.a., rational expressions for ductility offeredby confinement were produced as early as 1980.

International Codes for Aseismic Design was a field ofintensive participation for Tassios, e.g.:- CEB Aseismic Design Model Code (1980)- European Code for Aseismic Design (1980(1980-1996)- South-American
American Model Code for Aseismic Design

Dimensioning of repaired or strengthened elements is basedon resistances mobilized by allowable cyclic slips between
existing and added materials.

A methodology was developed for practical seismic
assessment and strengthening of R.C. structures, based on
simplified (but rationally calculated) ductility factors, before
and after structural intervention. To this end, each structuralelement is modified (repaired or strengthened) if needed,according to the locally required displacement ductility factors
dictated by the targeted overall behaviour factor (oraccording to the locally needed chord angles).

His teaching activities include 30 years of courses at NTUA

monuments is another research field of Tassios’ Group.
Engineering analytical models predicting strengths weredeveloped for several types of traditional masonries.

(i.a. “Theory of Redesign of Structural Interventions”). He
also taught as visiting Professor:- “Soil Dynamics’’, Bagdad Univ. 1979
- “Earthquake Engineering’’, Tongji Univ., Shanghai 1982
- “R.C. Aseismic Design”, Pavia Univ., 1986
- As Consultant Engineer, he was engaged with seismic
design and expert reports related to bridges, tunnels
and earth-dams.
