Actual waves are very complicated and can be sums of these three modes as well as sums of many frequencies of simple harmonic waves.  Understanding the basic properties of wave motion (amplitude/intensity, period/frequency, wavelength, wave speed) apply to all these modes, but the speeds of each mode, even in a common structure will differ, and the strength of the material of the structure will differ for each mode.


Bill!

There are a ‘huge” number of seismic engineering texts.  I have maybe a dozen of them from 1/2 price books.  They cover from seismic retrofitting, seismic laws (building codes), etc. to  modal analysis and quake prediction, etc.   Try:   Dynamics of Structures / A Primer   [Anil K. Chopra]    earthquake engineering research institute.  

In print and very expensive:  Dynamics of Structures (4th Edition) (Prentice-Hall International Series in Civil Engineering and Engineering Mechanics): Anil K. Chopra: 9780132858038: Amazon.com: Books 

less expensive:

Dynamics of Structures - Alibris Marketplace  

http://www.alibris.com/booksearch?browse=0&keyword=Dynamics+of+Structures+&mtype=B&hs.x=36&hs.y=11&hs=Submit  


another choice:

chopra - "dynamics of structures" - AbeBooks  

http://www.abebooks.com/servlet/SearchResults?an=chopra&sts=t&tn=%22dynamics+of+structures%22  




bc,  likes “Structure and dynamics of Earth’s Deep Interior”  includes, e.g.  The excitation of Core Modes by Earthquakes.
