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 ...

Comparison of crack segmentation using digital image correlation measurements and deep learning

Radhakrishna Achanta, Katrin Beyer, Amir Rezaie, Michele Godio

Reliable methods for detecting pixels that represent cracks from laboratory images taken for digital image correlation (DIC) are required for two main reasons. Firstly, the segmented crack maps are used as an input for some DIC methods that are based on di ...

Quantifying the out-of-plane response of unreinforced masonry walls subjected to relative support motion

Katrin Beyer, Michele Godio

The supports of out-of-plane loaded unreinforced masonry walls in buildings are subjected to a motion that is filtered and amplified by the building structure and, in some cases, can be significantly different from the ground motion. Moreover, because thes ...

Numerical investigation of the role of masonry typology on shear strength

Katrin Beyer, Shenghan Zhang

The force-displacement behavior of masonry elements depends on the properties of their constituents, mortar and unit, as well as on their typology, i.e., the shape and size of the units and the patterns they generate. Up until now, only few numerical studi ...

Ductility reduction factor formulations for seismic design of RC wall and frame structures

Katrin Beyer, Matteo Zerbin

Seismic design of standard structures is typically founded on a force-based design approach. Over the years this approach has proven robust and easily applicable by design engineers and - in combination with capacity design principles - it provides a good ...

Experimental investigation on the deformation capacity of lap splices under cyclic loading

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

Correct detailing and positioning of lap splices is essential in order to prevent premature failure of reinforced concrete structural members. Especially before the introduction of capacity design guidelines, lap splices were often placed in member regions ...

Trilinear Model for the Out-of-Plane Seismic Assessment of Vertically Spanning Unreinforced Masonry Walls

Katrin Beyer, Michele Godio

Out-of-plane failure of masonry walls is often responsible for the partial collapse of unreinforced masonry structures. Modeling the out-of-plane response of these walls is therefore key in the assessment of existing buildings. The paper presents a new tri ...

Quasi-static shear-compression tests on stone masonry walls with plaster: Influence of load history and axial load ratio

Katrin Beyer, Shenghan Zhang, Francesco Vanin, Michele Godio

This paper describes quasi-static cyclic shear-compression tests on six plastered single-leaf stone masonry walls. Of the six walls, four are tested under different axial load ratios, performing a cyclic load history with two cycles per increasing drift de ...

Shear to elastic modulus ratio in unreinforced masonry

Katrin Beyer, Bastian Valentin Wilding, Michele Godio, Leilah Yadia Kelly Sory

In the seismic design of unreinforced masonry walls, the elastic modulus E and shear modulus G are essential parameters for the calculation of the in-plane wall stiffness. Current codes provide empirical estimates of the elastic modulus and furthermore a r ...

Uniaxial Cyclic Tests on Reinforced Concrete Members with Lap Splices

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

This data paper presents the quasi-static uniaxial cyclic tests of 24 reinforced concrete members, of which 22 feature lap splices and 2 are reference units with continuous reinforcement. The objective of the experimental program is to investigate the infl ...

Shake-Table Test of a Strengthened Stone Masonry Building Aggregate with Flexible Diaphragms

Katrin Beyer, Andrea Penna

A unidirectional shake-table test was performed on the half-scale prototype of a natural stone masonry building aggregate, to investigate the seismic performance of this type of historical construction and to assess the effectiveness of two retrofit soluti ...

Numerical evaluation of test setups for determining the shear strength of masonry

Katrin Beyer, Nicolas Richart, Shenghan Zhang, Lyne Desharnais

The bond shear strength between masonry units and mortar is the weakest link in a masonry wall. Different material tests have been developed in order to characterize this bond behaviour. The objective of this study is to evaluate three common test setups t ...

Experimental investigation on the behaviour of lap splices under uniaxial cyclic loading

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

Splicing of longitudinal reinforcement in the plastic hinge region of reinforced concrete (RC) members was common practice in buildings and bridges before the introduction of capacity design principles. Experimental and field observations showed that the p ...

Mechanical Model for Drift-Induced Punching of Slab-Column Connections without Transverse Reinforcement

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

A mechanical model is presented for predicting the momentrotation relationship of interior slab-column connections without transverse reinforcement when subjected to seismically induced drifts. The model accounts explicitly for the three load-transfer acti ...
