Methodology for assessment of amount and amplitude of thermal stress cycles in masonry

Popis výsledku v původním jazyce

Analysis of amount and amplitude of thermal stress cycles in historic masonry has been made by means of combination of three 2-D numerical models of heterogeneous ashlar masonry. The numerical models were used to simulate thermal stress cycles during June, July and August in reference climatic year valid for Prague Castle, Czech Republic. For evaluation of amplitude and amount of the thermal stress cycles the effective stress in selected point in masonry was used. Afterwards rainflow method was used to count the amplitude and amount of the stress cycles. The results show that during summer quite a lot of significant thermal stress cycles originate in masonry, especially during sunny hot days. The results presented in this paper confirm the significant fatigue character of the thermal stress cycles and the method presented here could be suitable to evaluate thermal stress in building materials and structures.
