The recognition of the actual condition of the historical structure (diagnosis) is however not only achieved by determining the reason for an already detected defect. It is necessary also to determine the effect of any impact, and also during decision-making, whether at all, or how long the older structure could be in further safety. Long-term dynamic loads represent a serious factor which compromise the safety and durability of historical buildings. Continued exposure to these types of loads contributes to the degradation of materials and joints, causing the initiation of cracks or the growth of existing ones, such that they may endanger the structure. Loads, which an undamaged structure could securely resist, can be critical if repeated numerous times. This risk is present in various types of historical buildings, and is influenced by changes in vibration magnitude, by the distance from their source, and by the quality of the building's maintenance. Good maintenance, which includes regular inspections, affords early detection of any emerging damage and its subsequent repair. This article describes the methods and results of the measurement of dynamic response to road traffic and other types of technical seismicity in two historic buildings. One of the negative aspects of the technological progress is the threat to historical heritage by the impacts of expanding production, transport, mining or blasting. The goal of the paper is the analysis and evaluation of the effect of such human induced vibrations on historical buildings and monuments.
