Structural R/C cores are a popular and efficient choice as lateral-load resisting system in medium to tall buildings. The walls of the cores typically present large openings providing access to elevators placed within them. Shear induced by lateral forces ...
Braced frames are often used to resist lateral earthquake loads in steel buildings, but braces can interfere with architectural features. Eccentrically braced frames (EBFs) will accommodate windows, doors, and halls, but have performance limitations when l ...
Fragility functions that permit the estimation of damage in pre-1994 welded flange bolted-web beam-to-column moment connections are developed. The fragility functions provide estimates of the probability of yielding and of experiencing fracture as a functi ...
Damage spectra for reinforced concrete buildings in Greece are presented in this paper based on a series of time-history nonlinear dynamic analyses for single-degree-of-freedom systems (Clough hysteresis model) with different deformation ductility and yiel ...
In many unreinforced masonry (URM) buildings reinforced concrete (RC) ring beams are introduced at each storey in order to maintain the integrity of the building when subjected to seismic loading. Such ring beams also contribute to the in-plane resistance ...
Current seismic risk evaluations are mostly based on approximate vulnerability curves. Damage prediction is improved by considering structural characteristics of building. Such improved fragility functions do not exist for many structures, especially in co ...
The Steel Slit Panel (SSP) is studied for its viability as a lateral force resisting system (LFRS) for regions of high seismicity. Anticipated benefits for the SSP are architectural flexibility, as well as repair and retrofit possibilities. This paper is f ...
