Numerical Modelling of FRCMs Confined Masonry Column

Key Engineering Materials, 2019
The Fabric Reinforced Cementitious Matrices (FRCMs) are promising strengthening solution for existing masonry since the inorganic matrix is considerably compatible with historical substrates. Nevertheless, the matrix is responsible for the stress-transfer in composites so, in case of poor-quality mortar, the effectiveness of the strengthening can be ...

Masonry columns confined by composite materials: Design formulae

Composites Part B: Engineering, 2011
Abstract The present paper is aimed at assessing analytical formulations and calibrating an accurate and reliable design formula for FRP-confined masonry columns. After a short introduction about the key issues regarding the confinement of masonry columns by means of composite wrapping, a wide experimental database is assembled in a second section of

Confined and Reinforced Masonry Buildings

2015
Masonry structures would continue to be built in large numbers in spite of masonry not being an ideal material under seismic impact. As a result, a large population in rural India will continue to live in such abodes. Hence, it is important to provide guidelines which, if followed, can minimise damage and save many lives in the event of an earthquake ...

Numerical modelling of non-confined and confined masonry walls

Construction and Building Materials, 2013
Abstract This paper presents a discussion on the behaviour of non-confined and confined masonry walls with different types of horizontal reinforcement when subjected to in-plane horizontal loads, using advanced numerical simulations. An isotropic continuum nonlinear finite element macromodel, based on smeared crack total strain–stress models with ...

FRP Confinement of Square Masonry Columns

Journal of Composites for Construction, 2009
The problem of masonry columns subjected to structural deficiency under axial load was studied and reported in this paper. The results of an extensive experimental campaign are presented in order to show the behavior of columns built with clay or with calcareous blocks, commonly found in southern Italy, especially in historical buildings.

Seismic behaviour of confined masonry walls

Earthquake Engineering & Structural Dynamics, 1997
The results of tests of plain and confined masonry walls with h/l ratio equal to 1·5, made at 1:5 scale, have been used to develop a rational method for modelling the seismic behaviour of confined masonry walls. A trilinear model of lateral resistance–displacement envelope curve has been proposed, where the resistance is calculated as a combination of ...

Masonry Confinement with Fiber-Reinforced Polymers

Journal of Composites for Construction, 2005
The application of fiber-reinforced polymer (FRP) as a means of increasing the axial capacity of masonry through confinement, a subject not addressed before, is investigated in this study. Four series of uniaxial compression tests, with a total of 42 specimens, were conducted on model masonry columns with these variables: number of layers, radius at ...

Differentiation between the terms ”confined masonry“ and ”infill masonry“

Mauerwerk, 2018
AbstractThis publication concerns the differentiation between the terms ”confined masonry“ and ”infill masonry“ using the example of the national technical approval Z‐17.1‐1145 – POROTON S9 MW –vertically perforated clay units with integrated thermal insulation using thin layer mortar [1].

FRP-confined masonry columns

2009
Historical buildings are often prone to brittle failures due to their lack of structural redundancy and robustness. Safety is guaranteed until the strength of masonry elements is reached; in the post-cracking field there are not significant resources that allow the structure to maintain its structural integrity.

EXPERIMENTAL TESTS OF CONFINED MASONRY WALLS

2010
Buildings with confined masonry have performed favorably in the past earthquakes in fact much better than masonry structures. The calculation method for confined and unconfined masonry is the same. Concrete of the ties and ties itself remain as the second line of defense or additional safety that is not numerically taken into account.
