Book Description
This book represents a significant step toward a new contribution in the process of developing the seismic vulnerability index. This is accomplished by releasing or reducing the role of the rapid visual screening that is created by the opinions and decisions of experts, which depend on observations made while investigating the vulnerability damages caused by earthquakes. Alternatively, the computational analytical technique is preferable since it can be effective in determining the seismic vulnerability index before the occurrence of an earthquake by modeling the most affected influencing parameters that regulate the building performance. In addition, the seismic vulnerability index is supported by the vulnerability curves, which describe the probability of damages and are used to estimate the economic damage grade for each building which is the topic of inquiry. In the end, this helps to establish a clear vision and sort of recommendations for engineers and specialists to follow in order to take into consideration certain indices and factors before designing any specific structure. Because of this, the simplified work is utilized to manage and put into action measures that will protect against the effects of seismic events before an earthquake really occurs. In addition to this benefit, the work that has been done is of significant assistance to the authorities that are accountable for the restoration of the preexisting buildings and the cultural heritages.

Book Description
Seismic Vulnerability Assessment of Civil Engineering Structures at Multiple Scales: From Single Buildings to Large-Scale Assessment provides an integrated, multiscale platform for fundamental and applied studies on the seismic vulnerability assessment of civil engineering structures, including buildings with different materials and building typologies. The book shows how various outputs obtained from different scales and layers of assessment (from building scale to the urban area) can be used to outline and implement effective risk mitigation, response and recovery strategies. In addition, it highlights how significant advances in earthquake engineering research have been achieved with the rise of new technologies and techniques. The wide variety of construction and structural systems associated with the complex behavior of their materials significantly limits the application of current codes and building standards to the existing building stock, hence this book is a welcomed guide on new construction standards and practices. Provides the theoretical backgrounds on the most advanced seismic vulnerability assessment approaches at different scales and for most common building typologies Covers the most common building typologies and the materials they are made from, such as concrete, masonry, steel, timber and raw earth Presents practical guidelines on how the outputs coming from such approaches can be used to outline effective risk mitigation and emergency planning strategies

Book Description
Empirical Seismic Vulnerability and Resilience Assessment of Building Clusters analyzes the seismic vulnerability analysis of four types of structures and studies and discusses the evaluation of structural damage using risk analysis and shaking table test methods. It does not consider the contribution of typical empirical structural seismic damage data to structural vulnerability assessment and prediction. It is recognized that the impact of earthquakes on large-scale areas is extensive, not only on a building but also on a group of buildings. The book is based on the research background of typical seismic damage characteristics of 11 types of engineering structures. It analyzes the characteristics of the vulnerability of various structures and provides measures and methods to improve the vulnerability of various structures. Combined with probability risk, reliability, machine learning, and other means, vulnerability prediction and evaluation models are established, respectively, and the rationality of the models is verified by hundreds of onsite earthquake damage survey data. Increases engineers' theoretical and practical knowledge of field investigation to help improve their efficiency and the quality of future work Includes the analysis of hundreds of earthquake field survey data Provides a vulnerability assessment of diversified structural experience

Book Description
A detailed seismic performance assessment procedure has been developed for reinforced concrete frame buildings with masonry in-fill walls and reinforced concrete frames including shear walls. The procedure uses member damage functions, in terms of inter-story drift ratios, developed for the primary components: columns, beams, in-fill walls and shear walls. Analytical investigations carried out to determine the influence of a number of parameters on the damageability of components were combined with existing experimental data to develop component damage functions. A new approach has been developed to combine component damage states to determine the story and building level performance states. The procedure has been calibrated and compared with other procedures by predicting the observed performance of seven buildings exposed to recent earthquakes in Turkey. It was observed that the damage experienced by most of the components of these buildings was predicted satisfactorily, and that the observed building damage states were captured. The procedure can be used for a reliable performance assessment as well as performance-based design of the RC frame structures.

Book Description
Moderate to high levels of seismic hazard are present throughout the Pakistan and numerous collapsed by Oct. 8, 2005 Earthquake verified the seismic vulnerability of building type present in the country. Seismic retrofitting of existing structures is one of the most effective methods of reducing this risk. However, the seismic performance of the structure may not be improved by retrofitting or rehabilitation unless the engineer selects an appropriate intervention technique based on seismic evaluation of the structure. Current codes (BCP 2007) do not address the evaluation of seismic resistance of existing building stock, not designed in accordance with the philosophies of current seismic provisions. The primary purpose of this book is to carry seismic evaluation of buildings in the capital city of Pakistan, Islamabad and propose guidelines for Building Code of Pakistan. Owing to importance of the subject, various organizations in the earthquake threatened countries have come up with documents, which serve as guidelines for the assessment of the strength, expected performance and safety of existing buildings.

Book Description
Many more people are coming to live in earthquake-prone areas, especially urban ones. Many such areas contain low-rise, low-cost housing, while little money is available to retrofit the buildings to avoid total collapse and thus potentially save lives. The lack of money, especially in developing countries, is exacerbated by difficulties with administration, implementation and public awareness. The future of modern earthquake engineering will come to be dominated by new kinds of measuring technologies, new materials developed especially for low-rise, low-cost buildings, simpler and thus lower cost options for retrofitting, cost cutting and raising public awareness. The book covers all the areas involved in this complex issue, from the prevention of total building collapse, through improvement techniques, to legal, financial, taxation and social issues. The contributors have all made valuable contributions in their own particular fields; all of them are or have been closely involved with the issues that can arise in seismic zones in any country. The recent research results published here offer invaluable pointers to practicing engineers and administrators, as well as other scientists whose work involves saving the lives and property of the many millions of people who live and work in hazardous buildings.

Book Description
The 2010-11 Canterbury and 2016 Kaikoura seismic events led to the identification of several vulnerabilities in existing older-type and modern reinforced concrete (RC) frame structures. By mid-2017, the New Zealand parliament approved the Building Amendment Act 2016 which set new requirements for managing earthquake-prone structures. However, owing to a lack of sufficient knowledge on the seismic response of reinforced concrete (RC) frame structures on the global and component level, codified seismic assessment provisions in New Zealand and overseas are inherently conservative or not suited for structures with specific vulnerabilities; leading to unwarranted retrofits or building closures. Aside from the over-exaggerated risks to community seismic resilience, the high costs of these unwarranted retrofits pose a significant financial burden on New Zealand's economy. To address this, the main objective of this research is to develop refined seismic assessment provisions that can be adopted for the identification and intervention prioritisation of the most earthquake-vulnerable structures. A survey of the NZ assessment guidelines and overseas standards highlighted specific provisions that need to be improved. These include provisions for: (a) evaluating the yield rotation of beam-column RC components; (b) accounting for the influence of biaxial seismic demands on RC columns; (c) assessment of beam-column RC components susceptible to single-crack plastic hinge response; and (d) accounting for uncertainty in component failure mode in seismic assessment of frame structures. This thesis has been developed to address each of the aforementioned issues. Using a collated experimental database of columns, beams and coupling beams with normal- and high-strength longitudinal steel, simple mechanistic formulations were developed for estimating the yield rotation and effective stiffness of beam-column components. The proposed formulations explicitly account for the contribution of bar slip and shear deformations, as a function of aspect ratio, using a proposed coefficient. To address the absence of specific provisions for accounting for the influence of biaxial seismic demands on RC columns, a dataset of past tests on columns subjected to biaxial lateral demands was collated. Analysis of the dataset was used to identify the characteristics and effects of biaxial lateral displacement paths on the seismic response of RC columns. Using the available ii dataset, recommendations were provided on how the influence of biaxial lateral load on lateral strength, deformation capacity, and stiffness degradation can be accounted for. A failure mode-based approach was proposed to improve provisions for seismic assessment of components susceptible to single-crack plastic hinge response. Firstly, a database of past tests on columns with smooth reinforcement was collated. This database was then used to validate a proposed mechanistic formulation for estimating the rocking capacity of columns with smooth reinforcement. Furthermore, an experimental program was carried out on six full-scale beams which are replicas of beams observed to have exhibited a single-crack plastic hinge response following the 2016 Kaikoura earthquake. This experimental program provides data on seismic performance, repairability, and residual capacity of beams with curtailed bar detailing. Using these test data, formulations were proposed for seismic assessment of beams with curtailed bar detailing. The final part of this thesis focuses on a probabilistic failure mode-based approach. Experimental and analytical studies were carried out to demonstrate the existence and influence of component failure mode variability on the collapse response of RC components and frame systems. This source of uncertainty was previously neither recognised nor incorporated into probabilistic seismic assessment frameworks. It was shown that nominally identical components may exhibit different failure modes due to inherent material uncertainty, strain rate and displacement history effects. To account for this, a failure mode transition zone was defined to identify components susceptible to failure mode variability. Furthermore, a probabilistic framework was proposed to account for the influence of failure mode variability in component collapse fragility estimate. The study was concluded by developing a framework for incorporating uncertainty in the global collapse mechanism into the performance-based earthquake engineering (PBEE) framework.
