Description

During the past earthquakes, we have witnessed extensive structural damage on modern high-rise buildings. The use of flat-slab or partially flat-slab system, inadequate seismic dilatation joints, occurrence of plastic hinges in columns, short columns mechanism, building additional storeys on already designed/constructed structures, inadequate transverse reinforcement in columns and beams and so on. The solution to the problem is in implementing the most recent knowledge in analysis, design and construction. The Institute of Earthquake Engineering and Engineering Seismology has established a methodology to improve the current practice procedures, enabling analysis and design of robust and economical reinforced concrete structures with controlled and conducted ductile behaviour of elements and systems in general, up to ultimate limit states of the strength and deformability. The process of designing stable and economic structures is extremely complex, due to the necessary harmonization of a series of parameters related to the construction on one hand and its response to actual earthquakes on the other.
The methodology and the dynamic response of real reinforced concrete buildings is presented here, through block diagrams and results from analysed examples. The reinforced concrete structures are designed with controlled and dictated ductile behaviour of the structural elements and the structure as a whole, for gravity/static loads and also for seismic/dynamic impacts that are expected for the defined location.

Keywords dynamic response; ductile behavior; reinforced concrete structures
