Changing of mechanic and physical properties of yellow pine metarial depending on time and climate in historical structures

Historical buildings can stand with their original form reflecting the history, used material and the load-bearing system. Istanbul is an important city in terms of historical buildings. With the increasing environmental problems, preservation of historical buildings became more important. The worst factor affecting a building is climatic conditions such as temperature, humidity and wind. In the historical building of the Florya Sea Mansion; Measurement of climatic factors on the material such as temperature, humidity and wind speed. Then, it is aimed to find the thermal conductivity differences of the samples as a result of bending, tensile and temperature change tests applied to the samples that placed in the structure in certain periods.The aim of the study is to determine effect such as temperature, humidity, wind speed, rain, sun and corrosion to scotch pine strength. It is aimed to make
