Punching shear failures of structural concrete members have been the focus of attention of numerous works presented over the last decades. Although various rational approaches have been developed to predict these failures, there is still no unanimity on a ...
Over the last few years the increasing demand of housing for low income population in Colombia and several neighboring countries, associated to the significant increase of cost of land, has prompted construction companies to build medium to high rise reinf ...
Reinforced concrete flat slabs constitute one of the most common and efficient modern construction methods. The design of such structural system might be governed by a brittle failure in the vicinity of the slab-column connection associated to punching she ...
As demonstrated by recent events in Italy, New-Zealand, Haiti, and Nepal, earthquakes continue to pose threats to civil infrastructure, including buildings. For a long time seismic ultimate limit states have not been considered in design codes for regions ...
Deformation-dependent punching shear resistance often constitutes the decisive design criterion for reinforced concrete slabs supported by columns. The increasing number of aging structures exhibiting insufficient punching resistance and detailing deficien ...
Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...
The material characterization of steel fibre-reinforced concrete (SFRC), which is required for its implementation in design codes, should be based on nominal properties that describe its postcracking strength in tension. In the case of brittle and quasi-br ...
Designing new concrete members and assessing the strength of existing elements subjected to in-plane stress state conditions is often conducted by means of Stress Fields (SF) and Strut-and-Tie Models (STM). These methods are usually accounting for identica ...
Post-reconnaissance findings after recent earthquakes have shown that the effect of the vertical acceleration component of the ground motion can be more damaging than typically considered thus far, particularly in near-field regions where the ratio of vert ...
Recent earthquakes in Chile (2010, M 8.8) and New Zealand (2011, M 6.3) have shown that, despite many years of extensive research and subsequent design code advancements, several modern reinforced concrete walls underperformed or even failed during these s ...
