However, its seismic performance in earthquake prone regions is a major concern. Majority of the research work which has been carried out for studying the failure pattern of masonry, either targets in-plane failure or out-of-plane failure of walls. However, various survey reports on the damage caused by earthquakes mention about failure of the corner walls of masonry structures such as those situated at the end of a row of structures, in a peculiar manner. Failure in such walls is characterized by the simultaneous overturning of a portion of orthogonal walls which is possible only if lateral loads act along the corners, implying each corner wall is subjected to bidirectional loading. Since the literature addressing such failure, are limited, therefore this study has been carried out to explore the reasons leading to corner failure of masonry structures.In this study, in order to examine the failure pattern at corner in dry masonry structures, finite element (FE) technique was adopted. Various masonry models with varying vertical load were subjected to dynamic loading along the corner to observe their combined effect on failure pattern. This analysis showed the pattern of propagation of crack through the bed joint along under varying dead load conditions. Since it is not possible to perform FE analysis for all the masonry structures, mathematical relations were derived to calculate the limiting acceleration at which corner failure can occur. These relations were obtained by assuming feasible failure mechanisms and applying the concept of limit state analysis. For studying the failure pattern of corner in mortar bonded masonry, the FE approach adopted for dry masonry was extended. Micro-modelling which is mostly adopted for modelling mortar bonded masonry was modified by introducing the concept of equivalent friction to simulate the behaviour of mortar in shear. Cracks were observed to pass through the bricks along with the bed joints which lead to toe crushing due to overturning of failure portion. Through this study an understanding of failure of the corner has been developed.

Download and read online ebook Earthquake-resistant Design Of Masonry Buildings write by Miha Tomazevic. This book was released on 1999-07-05. Earthquake-resistant Design Of Masonry Buildings available in PDF, EPUB and Kindle. In the last few decades, a considerable amount of experimental and analytical research on the seismic behaviour of masonry walls and buildings has been carried out. The investigations resulted in the development of methods for seismic analysis and design, as well as new technologies and construction systems. After many centuries of traditional use and decades of allowable stress design, clear concepts for limit state verification of masonry buildings under earthquake loading have recently been introduced in codes of practice.Although this book is not a review of the state-of-the-art of masonry structures in earthquake zones, an attempt has been made to balance the discussion on recent code requirements, state-of-the-art methods of earthquake-resistant design and the author's research work, in order to render the book useful for a broader application in design practice. An attempt has also been made to present, in a condensed but easy to understand way, all the information needed for earthquake-resistant design of masonry buildings constructed using traditional systems. The basic concepts of limit state verification are presented and equations for seismic resistance verification of masonry walls of all types of construction, (unreinforced, confined and reinforced) as well as masonry-infilled reinforced concrete frames, are addressed. A method for seismic resistance verification, compatible with recent code requirements, is also discussed. In all cases, experimental results are used to explain the proposed methods and equations.An important part of this book is dedicated to the discussion of the problems of repair, retrofit and rehabilitation of existing masonry buildings, including historical structures in urban centres. Methods of strengthening masonry walls as well as improving the structural integrity of existing buildings are described in detail. Wherever possible, experimental evidence regarding the effectiveness of the proposed strengthening methods is given.

Download and read online ebook Behavior of Unbounded Post- tensioned Masonry Walls write by Reza Hassanli. This book was released on 2018-08-07. Behavior of Unbounded Post- tensioned Masonry Walls available in PDF, EPUB and Kindle. This book reports on a comprehensive analytical, experimental and numerical study on the flexural response of post-tensioned masonry walls under in-plane loads. It explores an important mechanism in this new generation of structural walls, called “Self-centering”. This mechanism can reduce residual drifts and structural damage during earthquake ground motion, and is particularly favorable for structures which are designed for immediate occupancy performance levels. The book reports on the development and verification of a finite element model of post-tensioned masonry walls. It describes a detailed parametric study to predict the strength of post-tensioned masonry walls. New design methodologies and expressions are developed to predict the flexural strength and force-displacement response of post-tensioned masonry. Experimental study is carried out to better understand the behavior of post-tensioned masonry walls and also to evaluate the accuracy of the proposed design procedure and expressions. The book also includes an introduction to current research on unbounded post-tensioned masonry walls, together with an extensive analysis of previously published test results.
