Large alternating plastic amplitudes during seismic events frequently result in catastrophic fractures. Instable brittle failures are the result of insufficient deformation capacity in combination with non-appropriate toughness properties of the steel. Eurocode 3 provides a procedure for the...

The research project Meakado aims at developing adjusted design approaches for steel and steel-concrete composite structures in regions characterised by a low to moderate seismic activity. The methodology targets an optimal balance between safety and economical concerns. Two parallel ways are...

Nowadays, prequalification criteria for seismic resistant beam-to-column joints are missing in Europe. In addition, specific requirements and design rules for these joints are not provided by Eurocodes, which gives rules only for non-seismic joints, even though dissipative joints are allowed by...

Low-rise buildings are used for industrial and commercial activities. Most of these buildings are built by prefabricated-concrete elements characterised by low efficiency of connections and a lower ductility performance when subjected to earthquake loading. The proposal aim is defining...

The majority of existing buildings are in need of seismic retrofit. The main reasons are: the original design was not optimised with respect to the required safety level, poor construction quality, modifications or enlargements of buildings during their life and increase in the requirements of...

Earthquakes lead frequently to a large amount of damage. Conventional frames (moment resisting, concentric/eccentric braced frames) are not well positioned with regard to reparability. It is therefore advisable to develop structural systems that are simple to repair, i.e. to introduce the...

Despite modern seismic standards, like Eurocode 8, admit ductile design of steel and composite structures, current European production standards do not provide adequate limitations on steel mechanical properties limiting free application of such approach. Additional safety factors and design...

The aim of "HSS-SERF" project was to investigate and evaluate the seismic performance of dual-steel building frames, realized from two different steel grades: Mild Carbon Steel and High Strength Steel. A comprehensive set of dual-steel frames (moment resisting, concentrically and eccentrically...
