Initial Research

The article aims at presenting the initial results of damping parameters of vibrations in constructions with zeolite. The initial part of the article describes the properties and application of zeolite. The influence of zeolite on concrete parameters was examined. The main part of the article displays the results of the analysis of damping parameters of vibration of three plate-beam models. The models contain modified binder in which the part of cement was replaced by zeolite (containing more than 85% of crinoptylolite). The analyses were based on the induction of vibration of models, the measurements of vibrations, the spectrum treatment of time course as well as the determination of values of damping coefficients of vibration. Hence the collation method was used. Moreover, the damping coefficients of the first three modes of free vibrations of models were determined.

Time Courses

By destructive car tests are used acceleration sensors for the determination of a time courses of kinematic variables. The main task is to determine the velocity of measured points of selected objects. The fundamental problem in the solution of this problem is the fact that the acceleration sensor simultaneously record two mechanical movements. One of them is the movement of the object as a rigid body and the other is damped vibration of the object itself as a flexible body which is characterized by its dynamic parameters.
