Abstract:

It is a well-known fact that local ground conditions affect the seismic behavior of structures. Lastly, the earthquake-resistant building design principles, which were updated in 2018, have also changed the local floor classes. At the beginning of these changes, it is to bring new accounting approaches specific to the conditions where the ground is weak and the high floor structures. In addition, these special accounts have been compulsory to be controlled by experts. Considering the local ground conditions contained in the current earthquake regulations, cuts under the earthquake effects have been obtained for a flat frame that is located in a chosen concrete structure as an example. In any geographical point of Bitlis province, for five different local ground classes (ZA, ZB, ZC, ZD and ZE) the change of earthquake parameters has been first studied. For each floor class, the short map has been obtained spectral vibration ratio, the greatest ground vibration, the greatest ground speed, the spectral vibration ratio horizontal and the elastice design of the vibration spectral corner periods. Earthquake cuts are calculated by making calculations for a two-storey concrete structure using the values obtained for each local ground class. This study has calculated the effects on earthquake parameters and cuts, taking into account the changes in the ground classes in the new regulations.
