Article
Open AccessThe shear resisting actions in reinforced concrete elements without transverse reinforcement is analyzed by means of optimized strut-and-tie models with concrete ties. Biaxial failure criteria are used for uncracked and ... -
Analytical modeling of reinforced concrete columns subjected to bidirectional shear
(2017-05-01)
Article
Open AccessUnder general seismic loading, reinforced concrete columns may be subjected to lateral loads in more than one direction. Available experimental data on columns subjected to bidirectional forces indicate that higher levels ... -
