Evaluation of overstrength-based interaction checks for columns in steel moment frames

A study is presented to examine the implications of this guidance, which disregards the column interaction check (including both axial force and moment) under overstrength seismic loads. A set of thirteen steel moment frames are designed using multiple rul ...

Shear and steel-fibre reinforcement for the punching resistance of flat slabs at internal and edge columns

Diego Hernández Fraile

Reinforced concrete flat slabs consist of a continuous, thin concrete plate that rests on a grid of columns. The supporting surface of the columns is very small compared to the floor plan dimensions, leading to concentrations of shear forces near the colum ...

Experimental investigation of dowel action in reinforcing bars using refined measurements

Aurelio Muttoni, Marko Pejatovic

In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either expli ...

Reuse of concrete elements in architecture: characterisations and design methods for sustainable structures

Célia Marine Küpfer

Because of established demolition routines and low construction-material production costs that neglect negative externalities, discarded concrete today is crushed and landfilled or downcycled as infill material or recycled aggregates, wasting its embodied ...

Formulation of stress intensity factor under pure bending condition in multilayer pavements using numerical study and model tree approach

Seyed Mahmood Hamze Ziabari

The tensile deformation of top-down cracks significantly influences pavement delamination. Accurately formulating the stress intensity factor (SIF) is crucial for assessing the stress/strain near crack tips. In the present study, a robust data mining metho ...

Experimental and Analytical Investigation of Deflection of R-UHPFRC Beams Subjected to Loading-Unloading

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

Under service conditions, R-UHPFRC (Reinforced Ultra High Performance Fiber Reinforced Cementitious composite) beams exhibit residual deflection after loading-unloading. This is due to the tensile strain hardening behavior of UHPFRC. The precise calculatio ...

Foreword to the special issue "Adjacent Interacting Masonry Structures"

Katrin Beyer

This special issue focuses on the seismic performance of adjacent interacting masonry structures, particularly in historical European city centers. The AIMS project provided unique data on interacting masonry structures through large-scale shake table test ...

The new Chapter 9 of Eurocode 8 Part 3 for Seismic Assessment of Existing Steel Structures

Dimitrios Lignos

The seismic assessment of existing steel structures necessitates the development of practice- oriented engineering models for use in nonlinear static and dynamic analysis procedures. These models should encompass the full range of the anticipated nonlinear ...

Reuse of concrete components in new construction projects: Critical review of 77 circular precedents

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer

Extracting pieces of concrete from obsolete buildings and reusing them, as is, in new assemblies is today rarely considered a strategy for improving the sustainability of the construction sector. By delaying the crushing of concrete into aggregates and avo ...

Uniaxial Cyclic and Tensile Tests on Structural Metallic Materials

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Selimcan Ozden

Experimental data is imperative to characterize the behavior of materials used in structural analysis models. The aim of this data paper is to establish a database of material-scale uniaxial experiments, primarily conducted at EPFL, to assist with simulati ...

A theoretical framework for dynamic anticrack and supershear propagation in snow slab avalanches

Marin Mathieu Siron, Bertil Trottet

Snow slab avalanches release after the failure and collapse of a weak layer buried below a cohesive snow slab. The initial failure is induced by local overloading of the slab, such that the passage of a skier. This results in the propagation of a subsidenc ...

Simplified out-of-plane seismic behavior assessment of non-structural rocking walls

Pierino Lestuzzi

This paper provides a simplified tool for preliminary seismic assessment of the out-of-plane behavior of non-structural walls, such as unreinforced masonry partition walls, based on non-linear time-history analyses. The studies are performed using equivale ...

Seismo-VLAB: An Open-Source Software for Soil-Structure Interaction Analyses

Antonio Joaquin Garcia Suarez

In the fields of structural and geotechnical engineering, improving the understanding of soil-structure interaction (SSI) effects is critical for earthquake-resistant design. Engineers and practitioners often resort to finite element (FE) software to advan ...

Flat slab response for seismic and cyclic actions prediction with numerical models

Aurelio Muttoni

As an outcome of a recent European research project, the modelling of the response of flat slab structures for seismic and cyclic loading was the object of a blind competition. No other blind tests are available in the literature on this topic. The test re ...

Seismic performance of steel columns interacting with embedded column bases while exhibiting inelastic deformations

Dimitrios Lignos, Hiroyuki Inamasu

Observations from past earthquakes indicate that embedded column bases (ECBs) in steel moment resisting frames (MRFs) exhibited inelastic deformations while they were designed to be non-dissipative. Consequently, the amount of inelastic damage concentrated ...

LiBF4‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan

Thirteen palladium-ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF4 resulted in a profound structural rearrangement, converting a dincluclear [Pd2L4]2 comp ...
