METHOD AND APPARATUS FOR DYNAMIC SEISMIC RESEARCH OF BUILDINGS AND FACILITIES

摘要

1. A method for dynamic studies of earthquake resistance of buildings, comprising excitation of vibrations of the test object at the natural frequencies, oscillations arising registration with sensors mounted on the building or facility, converting mechanical to electrical signal with the subsequent processing of the data, characterized in that the action on the object produced by seismic waves excited surface seismic sources to be installed at a certain distance from the test object and of the recorded real time of forced oscillation and the foundation of the building object allocated frequency oscillations of the construction of the test object, based on an analysis which is based estimate the dynamic characteristics of the test object and the conclusion of its seismic resistance and residual resurse.2. The apparatus (hardware system) for research earthquake resistance of buildings, comprising a vibration exciter, a control system, recording devices vibrations imposed on the test object, the sensors for converting mechanical vibrations into an electrical signal, the apparatus registration of the sensor signals, characterized in that the oscillation exciter configured a vibration-wave seismic source vibrations (e.g. electro) installed on the ground (base) at a certain distance from the object, the geophones (accelerometers) mounted on the examined object and connected to a recording unit geophone signals.
