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.
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).
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.
30 de abr. de 2020 · The second part of this study proposes an improved equivalent boundary element model for the assessment of wall instability. Existing mechanical models, based on pinned-pinned boundary conditions, represent the boundary element over the height of the plastic hinge.
Instability of Thin Concrete Walls with a Single Layer of Reinforcement under Cyclic Loading: Numerical Simulation and Improved Equivalent Boundary Element Model for Assessment. Angelica Rosso, Lisandro A. Jiménez-Roa, João Pacheco De Almeida* & Katrin Beyer.
The boundary elements of the wall are subjected to the largest tensile strains and are therefore the wall parts most 37 prone to instability. Hence, out-of-plane buckling of RC walls has often been investigated by isolating the boundary element and
1 de ago. de 2018 · Large inelastic tensile strains and wide horizontal cracks primarily caused by in-plane loading, may lead to local out-of-plane deformations of the end regions of reinforced concrete (RC) walls within a buckled zone that comprises the plastic hinge length.
