ANALYSIS OF THE COLLISION EFFECT FOR ADJACENT STRUCTURES IN THE TIME-FREQUENCY DOMAIN

Many reinforced concrete structures are built side by in our cities. There very few applications of earthquake joints adjacent apartment buildings, most them were constructed completely adjacent. Adjoining buildings or any property should be protected from damage collapse during construction, restoration and demolition work. In case the static condition, protection must supplied for foundations, walls roofs. We have already observed many building collapses Turkey with a great number life lost. For there is need to understand structural system an existing manage risk. earthquakes like dynamic loading, essential. The Turkish Building Earthquake Code (TBEC) 2018 requires calculations vertical some types structures. left gap calculated height. It thought that this will prevent colliding. However, it has been subject research how performance change when produced floor offsets cause collisions at joints. study, different heights analyzed time domain specific motions. Collision situations more than two discussed making street model. Structural performances discrete obtained nonlinear analysis compared. motion parameters time-frequency wavelet Hilbert transforms. To determine effects joints, condition assessment detection studies carried out sufficiency seismic was discussed.
