traffic vibrations, dynamic, the impact of vibrations on people
Abstrakt
Newly designed buildings must meet conditions regarding the limit states of strength and serviceability. These conditions must be fulfilled in case of static load, dynamic load as well as both of them at the same time. Bearing in mind that the current sources of vibrations are located closer and closer to the neighborhood of inhabited buildings, particular attention should be paid to this issue. The mentioned problem of vibrations is even more important as it can concern loads (sources of vibrations) as well as buildings that are both existing and designed. It should, therefore, be considered - depending on the existence stage of the dynamic load and the building - four possible cases of analyzed problem. These are diagnosis, diagnosis with prognosis, designing and designing with diagnosis. The study describes methods of how to include in the design and protection of buildings the impact of traffic-induced vibrations on people staying at the facility. The criteria for assessing dynamic influences on people (as it is presented in codes) are specified. Particular attention was paid to the situation when we dealt with an existing road (vibration source) and designed a building. In this case, we are able to determine (by measuring in situ) parameters of kinematic excitation and then affect the FEM model of planned building to meet its dynamic parameters criteria's imposed during assessing of the impact of vibrations on people. The paper presents a calculation example of the building, which location is planned 12 m from the national road. Possible various technical conditions of the road surface including damaged surface and its permissible by national code unevenness that may occur in the surface course were considered. As a criterion for admission selected building to the operational state the provisions contained in the PN/B-02171:2017 Evaluation of the vibration influence on people in buildings were used. Since the main factors determining the fulfillment of the code requirements were the vertical accelerations during the analysis, author focused on choosing the appropriate thickness of slabs.
