Influence of Lap Splices on the Deformation Capacity of RC Walls. I: Database Assembly, Recent Experimental Data, and Findings for Model Development

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini, Ovidiu Prodan

Recent postearthquake missions have shown that reinforced concrete (RC) wall buildings can experience critical damage owing to lap splices, which led to a recent surge in experimental tests of walls with such constructional details. Most of the 16 wall tes ...

Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi

Empirical drift capacity models for in-plane loaded unreinforced masonry (URM) walls are derived from results of quasi-static cyclic shear-compression tests. The experimentally determined drift capacities are, however, dependent on the applied demand, i.e. ...

Erdbebenüberprüfung von Natursteinmauerwerksgebäuden – das Basel-Projekt

Katrin Beyer, Andrea Penna

Im Jahr 1356 wurde Basel von einem Erdbeben mit einer geschätzten Magnitude von 6.6 er-schüttert. Während dieses Erdbebens und des nachfolgenden Feuers wurden grosse Teile von Basel zerstört. Ein solches Ereignis kann jederzeit wieder auftreten. Um vorbere ...

Estimates for the stiffness, strength and drift capacity of stone masonry walls based on 123 quasi-static cyclic tests reported in the literature

Katrin Beyer, Francesco Vanin, Dario Zaganelli, Andrea Penna

This paper summarises 123 existing quasi-static shear–compression tests on stone masonry walls and evaluates the results to provide the input required for the displacement-based assessment of stone masonry buildings. Based on the collected data, existing c ...

Internal slab-column connections under monotonic and cyclic imposed rotations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate seismicity. Current codes of practice determine the displacement capacity of slab-column connections using empi ...

Elemento de Viga Baseado em Formulação de Rigidez Enriquecido com Funções de Forma Adaptativas para Garantir Equilíbrio Axial

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

In the framework of Performance Based Earthquake Engineering (PBEE), assessing the inelastic behaviour of structures both at the global (force-displacement) and local (stress-strain) level is of priority importance. This goal is typically achieved by advan ...

Modelling approaches for inelastic behaviour of RC walls: Multi-level assessment and dependability of results

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

The severe damage and collapse of many reinforced concrete (RC) wall buildings in the recent earthquakes of Chile (2010) and New Zealand (2011) have shown that RC walls did not perform as well as required by the modern codes of both countries. It seems the ...

Effect of static and kinematic boundary conditions on the out-of-plane response of brick masonry walls

Katrin Beyer, Filippo Lucca

The Unreinforced Wall (URM) elements that are most susceptible to out-of-plane failure are wall elements of the upper storeys where the accelerations are largest. In modern URM buildings with reinforced concrete slabs, the out-of-plane mechanism involves t ...

Influence of boundary conditions on the out-of-plane response of brick masonry walls in buildings with RC slabs

Katrin Beyer, Marco Tondelli

In modern unreinforced masonry buildings with stiff RC slabs, walls of the top ﬂoor are most susceptible to out-of-plane failure. The out-of-plane response depends not only on the acceleration demand and wall geom-etry but also on the static and kinematic ...

Stability of thin reinforced concrete walls under cyclic loads: State-of-the-art and new experimental findings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) walls may not achieve the expected ductile response but could possibly be triggered by out-of-plane displacements ...

Out-of-plane behaviour of reinforced concrete members with single reinforcement layer subjected to cyclic axial loading: beam-column element simulation

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Earthquake loads can induce out-of-plane deformations in thin reinforced concrete (RC) walls that may lead to member out-of-plane failure or cause a premature in-plane collapse. Such instability phenomena have been observed after the recent earthquakes in ...

Simulação numérica da instabilidade de paredes finas de betão armado usando elementos de viga sujeitos a tração-compressão / Numerical simulation of instability of thin reinforced concrete walls using beam elements under tension-compression

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

The increasing demand for housing in Colombia and several neighbouring countries, together with the large relative cost of the materials, has prompted city administrations to build thin reinforced concrete (RC) wall buildings with a single layer of reinfor ...

Behaviour of U-shaped RC walls under quasi-static cyclic diagonal loading

Katrin Beyer, Raluca-Tereza Constantin

This article presents results from the experimental testing of two half-scale RC U-shaped walls under quasi-static cyclic bi-directional loading along the diagonal direction of the U-shaped section, which were recently completed at EPFL. The main objective ...

Effective stiffness of unreinforced brick masonry walls

Katrin Beyer, Bastian Valentin Wilding

Code design of Unreinforced Masonry (URM) buildings is based on elastic analysis, which requires as input parameter the effective stiffness of URM walls. Current approaches estimate the effective stiffness as fixed ratio of the gross sectional stiffness bu ...

Three-Parameter Kinematic Theory for Shear-Dominated Reinforced Concrete Walls

Katrin Beyer, Pia Hannewald, Boyan Iliev Mihaylov

This paper is aimed at addressing the need for physically accurate and computationally effective models for predicting the response of shear-dominated reinforced concrete walls. The presented theory is based on a three-degree-of-freedom kinematic model for ...

Deriving a load model for the braking force on road bridges: Comparison between a deterministic and a probabilistic approach

André-Gilles Dumont, Glauco Feltrin, Marc-Antoine Fénart, Katrin Beyer

The current provisions for the braking force in the Eurocodes are much more demanding than previously enforced national codes from most European countries. Hence, safety assessments of existing bridges may show a lack of compliance with the new safety requ ...
