Newmark and published by . This book was released on 1965 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion is presented of maximum response for multi-degree-of-freedom elastic systems considering five-degree-of-freedom systems in some detail, with some results for ten-degree-of-freedom systems and other systems for which data are available in the literature. Included are tabulations of response data computed from step by step integration of the equations of motion for five different forms of ground excitation on a number of systems having varying parameters of mass and stiffness distribution. The results are compared with the modal responses for the same systems, and general rules are developed for comparing the true responses with various combinations of the modal response data. Consideration is given to treatment of a multi-degree-offreedom system as a continuous shear beam, and some generalizations are drawn from the study which enable a better interpretation of the results of the specific data tabulated in the report. Some suggestions arising from the studies reported in Vol. IV are made to take into account the behavior of multi-degree-of-freedom systems in the inelastic range. (Author).

M. NEWMARK and published by . This book was released on 1966 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The supplement (to AD-627 516) contains a description of the computer program developed to study the dynamic response of multi-degree-of-freedom systems subjected to earthquake or blast-type ground motions. A description of the features and a derivation of the equations solved by the computer program are presented. The data input to the computer is defined by using a control card containing or preceding each type of input information. The purpose of each control card and the data is given with an example of some typical problems solved using the program. The final section contains the flow diagrams of the main program and each subroutine. (Author).

This book was released on 1964 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion is presented of response spectra for single-degree-of-freedom systems subjected to different forms of ground excitation. In the study of elastic systems, the sensitivity of the response to variations in the detailed characteristics of the input motion is discussed. For each class of forcing function, simple approximate rules are presented fo9 the construction of response spectra for undamped systems. Simple rules are described for the construction of spectra for complex input functions by compounding the spectra for the 'dominant' component pulses of the input function. In the studies of inelastic systems, primary attention is given to elastoplastic systems and, in an exploratory way, to bilinear systems of the softening type. Response spectra are presented from which the yield resistance required to limit the maximum deformation of the system to a prescribed multiple of its limiting elastic deformation can be determined directly. The maximum deformation of an inelastic system is related to that of an elastic system having the same initial slope in its resistance-deformation diagram and, for certain conditions, simple design rules are formulated for the construction of deformation spectra for elastoplastic systems in terms of the corresponding spectra for the associated elastic systems.

Newmark and published by . This book was released on 1965 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to develop simple rules for the designer so that he may be able to predict the maximum responses of two-degree-of-freedom elastic and inelastic systems under various types of ground shock excitation. The true responses of two-degree-of-freedom systems both in the elastic range and in the inelastic range, when subjected to five different forms of ground excitation are compared with the modal response of the same systems. Simple expressions are given for linear two-degree-of-freedom mass and spring combinations from which modal parameters can be obtained. From these modal parameters, and the response spectra for one-degree-of-freedom systems for various excitations, as presented in Vol. III (AD-444 989) of this series of reports, one can determine bounds and probable values of the response. A detailed study is reported of a two-degree-of-freedom system subjected to a step velocity pulse at the base, having various combinations of elastic and inelastic response. In addition, a series of solutions of two-degree-of-freedom systems are presented for comparison with various approximate rules for determining bounds to the response in the various springs of the system.

Download or read book Response Spectrum Method in Seismic Analysis and Design of Structures written by Ajaya Kumar Gupta and published by Routledge. This book was released on 2017-11-22 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: New developments in the response spectrum method have led to calculations in seismic stresses that are more accurate, and usually lower, than those obtained by conventional methods. This new textbook examines the wealth of information on the response spectrum method generated by the latest research and presents the background theory in simplified form. Applications of these methods is essential in the seismic design of critical structures, such as nuclear power plants and petroleum facilities. In new construction, the reduced seismic stresses will result in efficient and economic design. For facilities already built, these more accurate methods can be used where the facility is being reassessed for higher loads and in the calculation of margins. Written by an acknowledged expert in this and related fields, this volume is ideal as a graduate text for courses in structural and earthquake engineering. It is also an excellent reference for civil, structural, mechanical, and earthquake engineers.
