Seismic vulnerability assessment of free-standing massive masonry columns by the 3D Discrete Element Method

Jinwoo Kim

Free-standing masonry column is a recurrent typology of built cultural heritage. Usually raised without seismic design, columns are subject to intense rocking and overturning under strong ground motions. In this paper, a strategy to assess their seismic vu ...

Modelling reinforced concrete coupling beams designed for low-to-moderate seismic regions

Lisa Imperatori

Reinforced concrete (RC) coupling beams are often used to transfer and resist the earthquake loads. Coupling beams can improve significantly the stiffness and the strength of the all lateral resistant structure. By performing inelastically they decrease th ...

Seismic performance of slender RC U-shaped walls with a single-layer of reinforcement

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Ryan Hoult

Reinforced concrete walls are commonly used to resist the lateral loading induced by wind and earthquake actions. While most walls include two vertical reinforcement layers, some regions of the world construct slender, non-rectangular concrete walls with a ...

Earthquake energy budget

Marie Estelle Solange Violay

Earthquakes occur on planar faults that often mark the boundaries between tectonic plates that collide or slide against each other. During an earthquake, sudden slip on the fault releases elastic energy stored in the earth's crust or upper mantle, resultin ...

Development of collapse-consistent loading protocols for experimental testing of steel columns

Dimitrios Lignos

In order to effectively utilize results from quasi-static cyclic testing on structural components for the earthquake-induced collapse risk quantification of structures, the need exists to establish collapse-consistent loading protocols representing the asy ...
