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 ...

Development of a consistent approach for design and assessment of structural concrete members using stress fields and strut-and-tie models

Filip Niketic

Designing new concrete members and assessing the strength of existing elements subjected to in-plane stress state conditions is often conducted by means of Stress Fields (SF) and Strut-and-Tie Models (STM). These methods are usually accounting for identica ...

EPFL2017

This article introduces an analytical model to compute the monotonic force–displacement response of in-plane loaded unreinforced brick masonry walls accounting for walls failing in shear or ﬂexure. The masonry wall is modelled as elastic in compression wit ...

2017

The material UHPFRC is not yet used in the field of bridge construction regularly. The reasons are missing codes and allurements for innovation in the structural engineering. Nevertheless, UHPFRC has many advantages, which are significant compared to the u ...

Gusset Plate Connections for Naturally Buckling Braces

Hiroyuki Inamasu

A naturally buckling brace (NBB) is a steel brace that consists of a high-strength and low-yielding steel channel arranged in parallel with eccentricity acting along the brace length. To enhance the feasibility of NBB fabrication, three connecting design d ...

Size effect on punching shear strength: differences and analogies with shear in one-way slabs

Aurelio Muttoni, Miguel Fernández Ruiz

Size effect has been theoretically and experimentally acknowledged as a phenomenon influencing the shear and punching shear strength of concrete structures, with reducing unitary shear strength for increasing member sizes. For members failing in shear, as ...

2016

Wood/timber has been widely used for house and bridge construction. It is a widely available natural material that necessitates low energy for the production, following simple processes. The environmentally friendliness, together with the low cost of raw m ...

Influence of Fatigue Loading in Shear Failures of Reinforced Concrete Members without Transverse Reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário, Juan Manuel Gallego Martín

Shear fatigue of reinforced concrete members without transverse reinforcement has been observed to be potentially governing for the strength of some structural members subjected to large live loads of repetitive nature (as traffic, wind or wave actions). A ...

Journal of Advanced Concrete Technology2015

Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...

Stress Fields for the analysis of the faillure load and cracking state of dapped-end beams (Aplicación de modelos de campos de tensiones para el análisis en servicio y rotura de apoyos a media madera)

Aurelio Muttoni, Miguel Fernández Ruiz, Jaime Mata Falcon

The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...
