This book was released on 2015 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many high-rise buildings are practically irregular as a result of the architectural and service requirements in the design process, errors and modifications during the construction phase, and changes of the building use throughout its service life. Structural irregularities could increase the uncertainties related to the ability of the building to meet the design objectives. This study is thus devoted to assess the safety margins and calibrate the seismic design response factors of modern high-rise buildings with different vertical irregularity features. A brief survey of the most common vertical irregularities in reinforced concrete multi-story buildings is conducted to select reference structures. Five 50-story high-rise buildings are then selected and fully designed using international building codes to represent well-designed tall buildings with principal vertical irregularity types. Fiber-based simulation models are developed to assess the seismic response of the five benchmark buildings under the effect of forty earthquake records representing far-field and near-field seismic scenarios. The comprehensive results obtained from inelastic pushover and incremental dynamic analyses are employed to provide insights into the local and global seismic response of the reference structures. The probabilistic vulnerability assessment of the five high-rise buildings is conducted at different limit states using fragility relationships. The study concluded that the seismic performance of well-designed regular and vertically irregular high-rise buildings is satisfactory under the design earthquake. Under severe earthquakes, the seismic response of tall buildings with extreme soft story and geometric irregularity is not inferior to that of the regular vii counterpart at different seismic performance levels. Despite the overstrength factor adopted in the design of buildings with discontinuities in the lateral-force-resisting system and extreme weak story, the observed negative impacts of these irregularity categories on increasing the vulnerability of high-rise buildings are substantial. This confirms the pressing need for mitigation strategies to reduce the expected seismic losses of the latter classes of building. The calibration of seismic design response factors of the reference high-rise buildings also confirms that, although the code coefficients are adequately conservative, they can be revised to arrive at a more efficient and cost-effective design of regular and irregular high-rise buildings.

This book was released on 2020-03-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art knowledge on problems of the effects of structural irregularities on their seismic response. It also covers specific spatial and rotational seismic loads on these structures. Rapid progress in respective research on irregular structures and unconventional seismic loads requires prompt updates of the state of the art in this area. These problems are of particular interest to both researchers and practitioners because these are non-conservative effects compared with the approach of the traditional seismic design (e.g. Eurocode 8, Uniform Building Code etc.). This book will be of particular interest to researchers, PhD students and engineers dealing with design of structures under seismic excitations.

Download or read book Seismic Isolation Structural Health Monitoring and Performance Based Seismic Design in Earthquake Engineering written by Azer A. Kasimzade and published by Springer. This book was released on 2018-08-13 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features chapters based on selected presentations from the International Congress on Advanced Earthquake Resistance of Structures, AERS2016, held in Samsun, Turkey, from 24 to 28 October 2016. It covers the latest advances in three widely popular research areas in Earthquake Engineering: Performance-Based Seismic Design, Seismic Isolation Systems, and Structural Health Monitoring. The book shows the vulnerability of high-rise and seismically isolated buildings to long periods of strong ground motions, and proposes new passive and semi-active structural seismic isolation systems to protect against such effects. These systems are validated through real-time hybrid tests on shaking tables. Structural health monitoring systems provide rapid assessment of structural safety after an earthquake and allow preventive measures to be taken, such as shutting down the elevators and gas lines, before damage occurs. Using the vibration data from instrumented tall buildings, the book demonstrates that large, distant earthquakes and surface waves, which are not accounted for in most attenuation equations, can cause long-duration shaking and damage in tall buildings. The overview of the current performance-based design methodologies includes discussions on the design of tall buildings and the reasons common prescriptive code provisions are not sufficient to address the requirements of tall-building design. In addition, the book explains the modelling and acceptance criteria associated with various performance-based design guidelines, and discusses issues such as selection and scaling of ground motion records, soil-foundation-structure interaction, and seismic instrumentation and peer review needs. The book is of interest to a wide range of professionals in earthquake engineering, including designers, researchers, and graduate students.

Download or read book Dynamic Loading and Design of Structures written by Andreas Kappos and published by CRC Press. This book was released on 2001-10-11 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, information on the dynamic loading of structures has been widely scattered. No other book has examined the different types of loading in a comprehensive and systematic manner, and looked at their signficance in the design process. The book begins with a survey of the probabilistic background to all forms of loads, which is particularly important to dynamic loads, and then looks at the main types in turn: wind, earthquake, wave, blast and impact loading. The relevant code provisions (Eurocode and UBC American) are detailed and a number of examples are used to illustrate the principles. A final section covers the analysis for dynamic loading, drawing out the concepts underlying the treatment of all dynamic loads, and the corresponding modelling techniques. Throughout there is a focus on the modelling of structures, rather than on classical structural dynamics.
