Dynamics of Structures (Prentice-hall International Series in Civil Engineering and Engineering Mechanics)

Product Information

If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100. Therefore, it is suitable also for those readers who approach these subjects for the first time and who only have a basic understanding of mathematics (linear algebra) and static analysis of structures. Helps readers to understand and implement modern design codes, which increasingly require knowledge of vibration caused by man or the environment. This book uses carefully-selected worked examples to instil an understanding of the theories underlying widely-used computer analysis systems and show readers how to carry out simple hand calculations in structural dynamics.

If a load is applied sufficiently slowly, the inertia forces ( Newton's first law of motion) can be ignored and the analysis can be simplified as static analysis.

The static displacement can be calculated with u static = F 1 , eq k 1 , eq {\displaystyle u_{\text{static}}={\frac {F_{1,{\text{eq}}}}{k_{1,{\text{eq}}}}}} . Dynamic analysis for simple structures can be carried out manually, but for complex structures finite element analysis can be used to calculate the mode shapes and frequencies.

Taking a different approach, Structural Damping: Applications in Seismic Response Modification considers the dynamic responses of structures with added damping devices as systems governed by the combined effect of the static stiffness, period, and damping—or "dynamic stiffness"—of the structure-device system. As the number of degrees of freedom of a structure increases it very quickly becomes too difficult to calculate the time history manually – real structures are analysed using non-linear finite element analysis software. Summary: Textbook for courses on dynamics of structures, either at the senior or 1st-year graduate level. Dynamic loads can originate from many sources, including for example loading caused by geophysical phenomena such as wind, waves or earthquakes, or manmade sources such as traffic, explosive blasts, or other impacts. The current design process is simple and useful for adding supplemental damping up to a reasonable level—but it is not as useful with higher levels of damping.

Equation of motion for SDOF systems would be developed for periodic, non-periodic and arbitrary excitations.However, emphasis is also given to the applications of numerical methods for the solution of the equation of motion and to the ground motion selection to be used in time history analysis of structures. Although this is too simplistic to apply to a real structure, the Heaviside step function is a reasonable model for the application of many real loads, such as the sudden addition of a piece of furniture, or the removal of a prop to a newly cast concrete floor.

Finally, emphasis is given to the subject of seismic loading, which makes the book especially important and relevant to mechanical, structural and civil engineers working with these loads in mind.It uses simple language and terminology and the math is limited only to cases where it is essential to understand the physical meaning of the system. As supplementary materials, this book provides “OPENSIGNAL", a rare and unique software for ground motion selection and processing that can be used by professionals to select the correct earthquake records that would run in the nonlinear analysis.
