15 de jul. de 2022 · In cases where boundary elements are included, adequate confinement is not guaranteed due to their reduced thickness. Software tools allow verifying the behavior of these buildings under representative seismic events. This article studies the behavior of thin RC walls using the Non-linear Beam-Truss Model (NL-BTM).

30 de abr. de 2020 · Existing mechanical models, based on pinned-pinned boundary conditions, represent the boundary element over the height of the plastic hinge. This work shows that such models often underestimate the critical tensile strain triggering out-of-plane failure.
1 de dic. de 2018 · Thin concrete walls with unconfined boundary elements are evaluated experimentally. Limit states for the tested walls are proposed. Design limits and drift capacity are discussed in terms of the obtained response.
1 de mar. de 2020 · This data was used to analyze the behavior of rectangular thin slender walls in terms of axial load ratio, boundary elements conditions, plastic hinge length, and maximum drift capacity. The experimental data shows a significant reduction in drift capacity as axial load, clear interstory height to wall thickness ratio, or wall length ...
Performance of reinforced concrete (RC) walls in recent labora-tory tests and in recent strong earthquakes has revealed that thin wall boundaries are susceptible to concrete crushing, reinforcing bar buckling, and lateral instability.
11 de nov. de 2021 · This study's results are used to understand better the potential seismic behavior of thin RC walls with a single curtain of welded wire mesh fabric. The drift capacities of typical thin RC walls are estimated in a performance-based seismic design procedure for buildings with RC thin walls.
The boundary elements of the wall are subjected to the largest tensile strains and are therefore the wall parts most prone to instability. Hence, out-of-plane buckling of RC walls has often been investigated by isolating the boundary element and subjecting it to tension and compression cycles (Paulay and Priestley 1993).
