LUEVANOS-ROJAS, Arnulfo. Dynamics in systems of pipes with different movements in its ends. ing.cienc. [online]. 2010, vol.6, n.12, pp.117-144. ISSN 1794-9165.

In this document a method of dynamic analysis of systems of pipes with different movements in the ends sets out. This methodology takes the response spectrum corresponding to each one of the supports, and to compare it with the method of simple answer, that it uses a surrounding one in the response spectrum of the different supports is the classic one, in this last one they are not preservative, as it is possible to be noticed in the table of results of the considered problem. Therefore, the usual practice to consider the surrounding one of spectrum will not be a recommendable solution. Also the use of the consistent masses or distributed, and not discreet or concentrated them, as normally it is made, and in addition it is become attached but to the reality.

Keywords : influence matrix; modal analysis; spectral analysis; characteristic values; vectors; factor of modal participation; spectral acceleration; vector of normal coordinates principles.
