ABSTRACT

In order to determine a realistic behavior of the structure during earthquake action it is
necessary to apply realistic load conditions and real parameters of structure
characteristics. That can be fully accomplished only by testing the structure in full scale,
as proscribed by the Regulations of technical standards for construction of high-rise
structures in seismic areas, that is, experimental determination of dynamic
characteristics is performed on the finished structure by forced vibrations which will not
cause damage. Such tests produce quite satisfactory results in the field of elastic
behavior of materials and structures, which is presumed during the earthquake action,
i.e., the structure must not collapse.
In the paper is described experimental research of a five-storey building constructed in a
large panel prefabricated system taking into consideration the parameters of interaction
of soil and structure. On the basis of obtained parameters, and by testing the structure in
longitudinal and transversal directions and rotation, mathematical model of the tested
structure is formed, and through analytical procedure the expected, i.e. measured values
are calculated.
The relation force-displacement will be given for the linear model of the system
foundation-soil, and then will be given the equations of free vibrations in the matrix
form, on whose basis a computer program was mode.
