In‐plane strength of unreinforced masonry piers

Earthquake Engineering & Structural Dynamics, 2008
AbstractThe definition of adequate simplified models to assess the in‐plane load‐bearing capacity of masonry piers, in terms of both strength and displacement, plays a fundamental role in the seismic verification of masonry buildings. In this paper, a critical review of the most widespread strength criteria present in the literature and codes to ...

Damage Thresholds in Unreinforced Masonry

Australian Journal of Structural Engineering, 2008
In various regions of Australia, mines and quarries employ blasting, which some home owners believe causes cracking of non-structural components such as brick veneer. The first part of this paper reports on properties affecting damage thresholds of masonry subjected to shear load at a localised unit/mortar scale using off-axis prism tests and triplet ...

Strengthening of Unreinforced Masonry Buildings

Journal of Structural Engineering, 1986
A method is proposed for rehabilitation and strengthening of multi-wythe unreinforced brick masonry walls in buildings where they are the primary structural element for transferring load to the foundation. Shear tests were performed to determine the strength of newly manufactured small-scale specimens made with cement grout, sand/polyester grouts, and ...

Retrofitting unreinforced masonry

Botswana Journal of Technology, 2005
Unreinforced masonry (URM) walls are prone to failure and collapse when subjected to out-of-plane loads caused by earthquake or high wind pressures. This represents one of the main causes of injuries and loss of human lives and property in different parts of the world.

RESPONSE OF UNREINFORCED MASONRY BUILDINGS

Journal of Earthquake Engineering, 1997
A summary of dynamic measurements are presented that illustrate relations between linear seismic demand and true nonlinear response of unreinforced masonry buildings with flexible diaphragms and rocking piers subjected to a series of simulated earthquake motions.

Seismic Behaviour of Unreinforced Masonry

2019
The present paper assesses the safety of existing unreinforced building subjected to earthquake loading, considering uncertainty associated with various material properties. A static pushover analysis was carried out on an equivalent frame model of selected clay and fly ash brick masonry walls using two different load pattern as per ASCE/SEI 41-17 ...

Structural Design of Unreinforced Masonry

The Masonry Society Journal, 2002
Detailed comparisons of the empirical design and rational design procedures of the 1999 MSJC Code are presented for unreinforced masonry construction. Differences in design results between these two Code approaches are presented, and suggested modifications to minimize discrepancies in design results are included.

Acoustic tomography for evaluation of unreinforced masonry

Construction and Building Materials, 1997
A joint U.S./Italian effort is investigating the effectiveness of grout injection for repair of damaged or deteriorated masonry structures. A nondestructive acoustic tomographic imaging technique has been used throughout the program to determine the effectiveness of the repair processes.

Unreinforced Masonry Buildings

Unreinforced masonry is one of the earliest materials used in the construction of buildings. Many such buildings were therefore constructed prior to the introduction of seismic design requirements and tend to be highly vulnerable. Their age also means that unreinforced masonry construction often comprises some of our most important buildings from a ...

Nonlinear Dynamic Analysis of Unreinforced Masonry

Journal of Structural Engineering, 1998
A comprehensive analytical model has been developed and presented in this paper to study the response of unreinforced masonry to in-plane dynamic loads, including earthquake loads. The analysis has been implemented in a nonlinear finite element program. Masonry is treated as a nonlinear homogeneous orthotropic material. A failure envelope has also been
