Abstract: A  prestressed  composite  beam  structure  from  which  the expansion joints, which were inevitably used in the conventional prestressed composite beam structure can be removed so that  the structural and functional  problems owing to  the expansion joints can be  solved  and  the span of beans can be  lengthened, and construction materials  can be considerably saved.     The construction method in which the composite beams can be Dade  into  divided  short  beams  in  order  to  overcome  the difficulties of transportation and  handling in cases where the length of the prestressed   composite beam is long.  After the preflexion loads have been applied to the beam which was profiled in reverse to the sag curve of the continuous beam structure, concrete is cast and cured on the flange, and then the preflexion is removed.  The problems of the negative moment on the connection between the beams is solved by lifing or lowering the support.     For quick and easy assembling with the prestressed slab, the composite bean has shear key grooves and a reinforcing beam.

Inventor: JANCZYK GEORG-RAFFAEL
IPC: H04L12/54
Filed: 1995-12-28
Granted: 2008-04-01
Abstract: For a call-associated bit rate monitoring, it is provided that a count value (d) corresponding to the relationship between the maximally allowed transmission bit rate and the transmission bit rate declared for the connection and a minimum counter reading (W min) (or, respectively, a maximum counter reading (W max)) are determined during the course of the setup of the respective connection. Over and above this, the plurality of message cells appearing during the course of established connections is acquired by a global counter that is incremented by a value "1" at every appearance of a message cell. In response to the appearance of a message cell, a sum value (or, respectively, difference value) is additionally individually formed for the respective connection from a momentary counter reading maintained for the respective connection and the global counter reading. The sum value (or, respectively, difference value) is thereby compared to the minimum counter reading (or, respectively, maximum counter reading) in order to be able to identify a transgression of the transmission bit rate declared for the respective connection.
