Structural Dynamics: Theory and Computation - Hardcover

solution, are provided for calculation of the responses to forces or motions exciting the structure. The new chapters in earthquake-resistant design of buildings describe the provisions of both the 1985 and 1988 versions of the UBC (Uniform Building Code) for the static lateral force method and for the dynamic lateral force method. Other revisions of the book include the presentation of the New­ mark beta method to obtain the time history response of dynamic systems, and the direct integration method in which the response is found assuming that the excitation function is linear for a specified time interval. A modifi­ cation of the dynamic condensation method, which has been developed re­ cently by the author for the reduction of eigenproblems, is presented in Chap­ ter 13. The proposed modification substantially reduces the numerical operation required in the implementation of the dynamic condensation method. The subjects in this new edition are organized in six parts. Part I deals with structures modeled as single degree-of-freedom systems. It introduces basic concepts and presents important methods for the solution of such dynamic systems. Part II introduces important concepts and methodology for multi­ degree-of-freedom systems through the use of structures modeled as shear buildings. Part III describes methods for the dynamic analysis of framed struc­ tures modeled as discrete systems with many degrees of freedom.

This text discusses the analysis and design of structures subjected to dynamic forces or to earthquake excitations. It offers a clear presentation of the theory, combining illustrative examples with the use of computer programs for immediate corroboration of results and extension to larger dynamic systems. The book is divided into six sections initially treating structures modelled by the simple oscillator as single degree-of-freedom systems. It includes chapters for undamped and damped systems as well as methods of solution for dynamic systems. The second part introduces the reader to structures modelled as shear buildings and to the Modal Superposition Method in which the response is obtained as the combination of the responses of independent single degree-of-freedom systems. Part Three presents the dynamic analysis of structures modelled as two- or three-dimensional frames or trusses whilst Part Four contains two chapters that treat structures as continuous systems with distributed inertial and elastic properties. Part Five introduces the reader to random vibrations on structural dynamics using the discrete and fast Fourier transforms. Finally, the sixth part contains chapters on earthquake resistant design of buildings. Two independent sets of interactive menu-driven computer programs in structural dynamics and earthquake engineering are available in BASIC in compiled and non-compiled versions for implementation on IBM or compatible microcomputers. This book may be of interest to advanced undergraduate or graduate engineering students, professional engineers.
