Book excerpt: Slender masonry walls are often found in school gymnasiums, warehouses and other low-rise buildings. According to current North American masonry design standards, a slender wall is defined to have a height-to-thickness ratio of 30 or greater. These walls must satisfy several stringent requirements as they are more susceptible to second-order effects, and it is believed that they present early instability issues. However, only a few experimental tests have been conducted to understand the true nature of slender masonry walls. Moreover, recent studies show that provisions in the standards are overly conservative and lead to non-economical designs. This study is the starting point of a research campaign that aims to address the need for more experimental tests on full-scale slender masonry walls. A numerical model using the software OpenSEES proved to closely predict the response of slender masonry walls subject to a combination of vertical and out-of-plane loads. The model was used to perform a parametric study to understand the behaviour of these walls under a variety of conditions and propose a promising solution to increase the stiffness of concrete masonry walls. Results of the parametric study also showed that walls were unstable shortly after the reinforcement yielded, suggesting that the requirement of a ductile failure mode in the standards should be re-evaluated. Then, an 8.75 m tall concrete masonry wall was built on a specially designed test setup. The wall was tested under a combination of vertical and cyclic out-of-plane loads, and under pin-end conditions. The importance of having a displacement limit in the standards was evident after pushing the wall to a midspan displacement equal to the serviceability limit of h/180 (48 mm) required by S304-14. After unloading, the residual displacement at midspan was already equal to 8 mm, indicating some damage and loss of out-of-plane stiffness. After a few cycles and when the sensors had indicated yielding of the vertical reinforcement, the test was stopped. Sensor readings showed that the maximum moment was not located at midspan but higher. This suggests that different loading conditions may have been present in the test, such as a differential pressure applied by the airbag or some friction present on the pinned supports. It was also found that the neutral axis was within the face shell of the concrete block from the early stages of loading. This means that the grouted portion of the cross-section contributed very little to the wall response, probably only before cracking. It also shows that the ungrouted properties of the masonry are highly relevant for the response of these walls. The behaviour of the wall after cracking was mainly affected by the area and location of vertical reinforcement. If the vertical bars were defined as centrally located in the cross-section of the numerical model, the wall stiffness was underestimated when compared to test results. This may be explained if steel bars were deviated from their original position farther from the compressive face of the wall during the grouting process, resulting in a larger post-cracking stiffness and a larger yielding load.

Download or read book Earthquake-resistant Design Of Masonry Buildings written by Miha Tomazevic and published by World Scientific. This book was released on 1999-07-05 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The classic work on the evaluation of city form. What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller? To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion—imageability—and shows its potential value as a guide for the building and rebuilding of cities. The wide scope of this study leads to an original and vital method for the evaluation of city form. The architect, the planner, and certainly the city dweller will all want to read this book.
