Abstract Seismic activity in the last two decades validate urgent improvement requirement of ductile seismic design concept for MR RC frame structures. This necesity comes from unfavorable recorded response structures required to on-site actions. The same observations and conclusions (regarding soft storey ( G round F loor (GF) or C urrent (CF)) mechanism development energy dissipation process ...

Many recent research studies focused on the development of innovative seismic resilient structures by chasing objectives minimising both damage and repair time, hence allowing definition able to go back undamaged, fully functional condition, in a short time. In this context, present study investigates an type self-centring damage-free steel column base (CB) connection its beneficial effects whe...

Abstract The features of calculating structures for the action weak earthquakes are analyzed. Earthquakes with a recurrence 30 years and 50 considered. In first case structure is to operate normally without damage after earthquake. second damages allowed that do not affect possibility operation. Three issues emphasized: setting elastic damping characteristics reinforced concrete, formalization ...

A deterministic-stochastic subspace identification method is adopted and experimentally verified in this study to identify the equivalent single-input-multiple-output system parameters of the discrete-time state equation. The method of damage locating vector (DLV) is then considered for damage detection. A series of shaking table tests using a five-storey steel frame has been conducted. Both si...

Infilled frame structures are commonly used in buildings. Masonry infilled RC frames are the most common type of structures used for multi-storeyed constructions in the developing countries, even in those which are located in seismically active regions also. Masonry infill walls are mainly used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. In the presen...
