Download or read book Selected Strengthening Techniques for the Seismic Retrofit of Unreinforced Masonry Buildings written by Najif Ismail and published by . This book was released on 2012 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately two thirds of the fatalities caused by earthquakes in the last one hundred years have resulted due to the collapse of unreinforced masonry (URM) buildings. Poor performance of URM buildings was also observed in recent earthquakes such as the 2005 Pakistan earthquake, the 2008 Sichuan earthquake, the 2009 L'Aquila earthquake and the 2010/2011 Canterbury (New Zealand) earthquake sequence. The New Zealand URM building stock consists of mostly pre-1931 structures, with many of these buildings contributing to the country's architectural heritage. It was revealed in a recent survey that many of New Zealand's URM buildings have insufficient capacity to endure even a moderate earthquake but the concerns of heritage preservation makes demolition of these historic URM buildings undesirable, which results in seismic retrofit being necessary. Many seismic retrofit solutions have already been implemented in New Zealand, but the experimental database on their seismic behaviour is scarce. Consequently, the research reported here was undertaken to investigate the performance of URM walls when seismically retrofitted using three strengthening techniques, which were selected after an extensive literature review. The selected strengthening techniques are (i) unbonded posttensioning using threaded steel rods and sheathed greased strands, (ii) near surface mounting of high strength twisted stainless steel bars (NSM-TS), and (iii) surface application of polymer textile reinforced mortar (TRM). The selected seismic strengthening techniques were adapted for New Zealand URM buildings, and the performance of URM walls seismically strengthened using the adapted strengthening techniques was investigated by performing numerous full scale laboratory based and field tests. Based on the results of the experimental program empirical design equations were derived and checked for accuracy by comparing with current design equations and with experimental results. Finally, case studies were conducted to demonstrate application of these strengthening techniques for the seismic retrofit of historic URM buildings.

Available in PDF, EPUB and Kindle. Book excerpt: New Zealand’s built heritage tradition is one of persistence and innovation, that continues to evolve in response to social and environmental conditions. Extensive damage caused by natural disasters such as the Canterbury earthquake sequence (2010-2011) focused public sentiment on an overlooked historic construction typology: unreinforced masonry (URM) buildings. The findings of the Canterbury Earthquakes Royal Commission (2012) highlighted a high proportion of deaths that occurred in public places, as a result of collapsed nineteenth- and twentieth-century URM buildings during the earthquakes. Throughout New Zealand, many such buildings were built in clusters and therefore survive as historic areas or precincts. Arising from the need to address public urban safety in conjunction with privileging historic building fabric, this thesis employs architectural heritage conservation as a framework for examining New Zealand’s history, heritage, and seismic retrofit of URM precincts. Heritage conservation through seismic retrofit demands analysis of architectural and structural seismic design principles. The thesis examines the application of contemporary conservation theory through selected case studies that document and analyse the history, significance, and seismic retrofit initiatives for URM precincts in New Zealand. The principal research question is: how can an understanding of architectural history and heritage conservation inform the selection of seismic retrofit and structural upgrading solutions to privilege the historic fabric of URM building precincts in New Zealand? The theoretical basis and practical challenges informing the analysis are captured by a series of sub-questions, including: To what extent does international architectural heritage conservation theory address pre- and post-disaster seismic and structural upgrade of historic URM building precincts? How may a multidisciplinary precinct-scale approach to seismic retrofitting historic buildings help to achieve greater urban safety? This thesis shows that New Zealand cities and towns feature an evolving, living, architectural heritage tradition of URM construction, built between 1880 and 1930. Examining national and international discourse reveals a shift in focus of conservation principles and practice, from individual buildings to precinct. The documented histories of change and adaptation suggest that the local URM precincts should be treated as examples of a functioning, built heritage when considering pre- and post-earthquake interventions and future role.

Book excerpt: Heritage conservation and energy efficiency considerations have converged in recent years. While new construction has focused on improved thermal performance to achieve high comfort levels in an energy efficient manner, the retrofitting of existing buildings with the same principles has just started to be recognised as a strategic measure, since they form much of the building stock and often have poor environmental performance. In this context, heritage buildings play an important role and have the potential to lead as best practices. In fact, given their cultural significance, they are the most likely to remain for a long lifespan, so their adaptation to future demands is highly important. Although energy retrofitting was considered a threat to conservation until recent decades, it has now started to be recognised as a measure to help with the protection of heritage, ensuring healthy indoor environments for a longer lifetime. In Aotearoa New Zealand, however, there is a gap between heritage conservation practices and energy efficiency considerations. Existing policies for the adaptation of existing buildings only focus on other types of upgrades, such as seismic strengthening, fire safety and accessibility. In terms of industry practice, most refurbishment projects only include shallow improvements, without making deep modifications to energy efficiency and indoor comfort. With the Building (Earthquakeprone Buildings) Amendment Act 2016 that took effect in 2017, thousands of buildings are required to be retrofitted over future years, including thousands Unreinforced Masonry Buildings (URM) of great historic significance. While the requirements are only related to seismic retrofit, there is now the opportunity to integrate thermal upgrades into these interventions, in order to improve the energy performance and usability of these buildings in the future. This research analysed the possibilities of including energy upgrades as part of the seismic retrofitting of URM buildings in New Zealand, proposing a range of levels of intervention, considering a respectful approach to heritage fabric. It provided insights into the current performance of URM buildings in New Zealand, revealing that there are significant issues in occupants' comfort and current building energy consumption. It then proposed energy retrofit scenarios, which ranged from less invasive interventions up to more comprehensive retrofit packages aiming to achieve the EnerPHit standard, developed by the Passive House Institute. These interventions were then analysed in terms of impact on energy performance and compatibility with heritage conservation principles, with an assessment based on European standard EN 16883. This analysis showed that it is possible to achieve higher energy performance in a sensible way in URM buildings, and that these upgrades can help these buildings continue to serve a useful purpose in a lowcarbon context. The combined seismic and energy retrofit of historic URM buildings in New Zealand can serve as an example for the management of historic heritage, demonstrating that an integrated approach can help achieve long-term benefits in the spheres of energy performance, seismic resilience and conservation of heritage for the future.

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.
