This book was released on 2016-01-22 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Questo studio monografico si occupa di ‘Isolamento Sismico’, che rappresenta – com’è noto – un aspetto tecnico ben specifico ed anche rilevante dell’Ingegneria Sismica. Desidero qui mettere in evidenza che la motivazione, per la quale mi sono deciso di pubblicare questo saggio, non è solo di natura divulgativa, ma anche e soprattutto di concreta applicabilità. Infatti, per quanto il metodo descritto sia stato già numerose volte proposto a Conferenze Internazionali sull‘Ingegneria Sismica – sia come sommario che come memoria, ricevendo il più ampio consenso alla presentazione e alla pubblicazione nei relativi Atti congressuali da parte dei Comitati di Esperti di valutazione – tuttavia esso è rimasto ancorato alle pagine degli Atti senza riuscire ad emergere per le sue prerogative di efficacia, semplicità e concretezza operativa. Mi auguro così che, con l’attuale pubblicazione, destinata per ovvi motivi culturali ad una classe ben selezionata di specialisti nel campo dell’Isolamento Sismico, il metodo descritto possa raggiungere la finalità auspicata, di uscire cioè dall’ambito strettamente di stallo in cui si è trovata per vari anni per aspirare al raggiungimento del suo scopo fondamentale, cioè l’applicazione per pubblica utilità. Quanto sopra, però, non senza sottoporre il metodo d’isolamento proposto ad ulteriori verifiche analitiche e, soprattutto, ad indispensabili prove sperimentali. Il testo è in lingua inglese ed in lingua italiana.

Download or read book Structural Dynamics written by Mario Paz and published by Springer. This book was released on 2018-11-28 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sixth edition of Structural Dynamics: Theory and Computation is the complete and comprehensive text in the field. It presents modern methods of analysis and techniques adaptable to computer programming clearly and easily. The book is ideal as a text for advanced undergraduates or graduate students taking a first course in structural dynamics. It is arranged in such a way that it can be used for a one- or two-semester course, or span the undergraduate and graduate levels. In addition, this text will serve the practicing engineer as a primary reference. The text differs from the standard approach of other presentations in which topics are ordered by their mathematical complexity. This text is organized by the type of structural modeling. The author simplifies the subject by presenting a single degree-of-freedom system in the first chapters, then moves to systems with many degrees-of-freedom in the following chapters. Finally, the text moves to applications of the first chapters and special topics in structural dynamics. This revised textbook intends to provide enhanced learning materials for students to learn structural dynamics, ranging from basics to advanced topics, including their application. When a line-by-line programming language is included with solved problems, students can learn course materials easily and visualize the solved problems using a program. Among several programming languages, MATLAB® has been adopted by many academic institutions across several disciplines. Many educators and students in the U.S. and many international institutions can readily access MATLAB®, which has an appropriate programming language to solve and simulate problems in the textbook. It effectively allows matrix manipulations and plotting of data. Therefore, multi-degree-of freedom problems can be solved in conjunction with the finite element method using MATLAB®. The revised version will include: · solved 34 examples in Chapters 1 through 22 along with MALAB codes. · basics of earthquake design with current design codes (ASCE 7-16 and IBC 2018). · additional figures obtained from MATLAB codes to illustrate time-variant structural behavior and dynamic characteristics (e.g., time versus displacement and spectral chart). This text is essential for civil engineering students. Professional civil engineers will find it an ideal reference.

Download or read book Performance of Innovative Controlled Buildings Under Resonant and Critical Earthquake Ground Motions written by Izuru Takewaki and published by Frontiers Media SA. This book was released on 2018-11-23 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eBook is the fourth in a series of books on the critical earthquake response of elastic or elastic-plastic structures under near-fault or long-duration ground motions, and includes six original research papers which were published in the specialty section Earthquake Engineering in ‘Frontiers in Built Environment’. Several extensions of the first eBook, the second eBook and the third eBook are included here. The first article is on the comparison of earthquake resilience of various building structures including innovative base-isolation systems and control systems. Pulse-type ground motions and resonant harmonic ground motions are used for investigating the earthquake resilience of those innovative building structures. The second article is concerned with the performance of an innovative seismic response controlled system with shear walls and concentrated dampers in lower stories. The resonant one-cycle sine waves and resonant harmonic waves are used as the input ground motions. The third article is related to the robustness evaluation of a base-isolation building-connection hybrid controlled building structure under the critical long-period and long-duration ground motion. The multi impulse is used as a substitute for a long-period and long-duration ground motion and the model reduction to a single-degree-of-freedom (SDOF) system is conducted to propose a simple response evaluation method. The fourth article is an extension of the previously proposed energy balance approach to a damped bilinear hysteretic SDOF system under a double impulse as a substitute for a near-fault ground motion. The energy absorption through viscous damping is incorporated appropriately in the energy balance and the application of the proposed method to actual recorded ground motions is presented. The fifth article is on the robustness evaluation of base-isolation building-connection hybrid controlled building structures considering uncertainties in deep ground. The earthquake ground motion amplitude at the earthquake bedrock is evaluated by the Boore’s stochastic method in 1983 including the fault rupture and the wave propagation into the earthquake bedrock. Then the phase angle property at the earthquake bedrock is investigated by introducing the concept of phase difference which is defined for each earthquake type. A wave at the ground surface nearly resonant to the base-isolation building-connection hybrid controlled building structure is produced by considering uncertainties in deep ground. The sixth article is concerned with the critical response of nonlinear base-isolated buildings considering soil-structure interaction under a double impulse as a substitute for a near-fault ground motion. The complicated model of a nonlinear base-isolated building on ground is modeled into an SDOF system after a few model reduction processes. The approach presented in this eBook, together with the previous eBooks, is an epoch-making accomplishment to open the door for simpler and deeper understanding of structural reliability and resilience of built environments in the elastic-plastic and nonlinear range.
