Abstract

In the article problem of a comprehensive diagnosis of a historic building with damages is discussed. Dynamic investigations carried out in the church of St. Nicholas in the center of Krakow are an example of diagnostic tests provided to determine the causes of damage. Because the tested structure is exposed to traffic vibrations caused by wheeled vehicles and train passes, special attention has been paid to the impact of these vibrations onto a historic object. Results of measurements of these vibrations as well as dynamic analyzes obtained using FEM model of the investigated church were given.

Highlights

A long with the development of road infrastructure, the sources of transport vibrations are brought closer to the existing buildings including historical objects
Dynamic diagnosis regarding the historical church in Krakow [1] may be a good example confirming the above statement
Indication that there is no need to strengthen the ground under foundations, indication - in the current traffic and rails conditions – as the most appropriate solution causing reduction of vibrations transmitted to the structure by applying vibration isolation in the construction of railway tracks, which are passing in the vicinity of the church, the level of stress caused by the loads caused by the passage of trains and cars showed that they do not affect the safety of the structure indication of the need to repair damage observed in the walls and provision of the protection works scope

Summary

Introduction

A long with the development of road infrastructure, the sources of transport vibrations are brought closer to the existing buildings including historical objects. Diagnostics of the technical condition of these objects cannot ignore the influence of vibrations generated during the passage of vehicles. Appropriate diagnostic analyzes should be carried out taking into account the current impact on the building and occurring in the past. Dynamic diagnosis regarding the historical church in Krakow [1] may be a good example confirming the above statement. It is worth disseminating the procedure used to develop this diagnosis
