The building was built at the beginning of the 20th century in Kadıköy, a residential district in the Asia side of Istanbul. <o:p> </o:p> <o:p>  </o:p> <p class="MsoNormal" style="margin-top:0cm;margin-right:-.05pt;margin-bottom: 0cm;margin-left:0cm;margin-bottom:.0001pt;text-align:justify;text-justify:inter-ideograph; text-indent:14.2pt;line-height:99%;tab-stops:404.0pt"> Material and Methods: Ultrasonic stress wave test was carried out on specimens prepared from the structural members. Following the ultrasonic based non-destructive tests, the bending strength and modulus of elasticity in the bending tests were determined for the specimens. <o:p> </o:p> <o:p>  </o:p> <p class="MsoNormal" style="margin-top:0cm;margin-right:-.05pt;margin-bottom: 0cm;margin-left:0cm;margin-bottom:.0001pt;text-align:justify;text-justify:inter-ideograph; text-indent:14.2pt;line-height:93%;tab-stops:404.0pt"> Main results: According to the results of the experiments, it was observed that the regression correlations were high for the softwoods (fir and spruce), but relatively lower correlations were obtained for the chestnut specimens. <o:p> </o:p> }, number={3}, publisher={Kastamonu Üniversitesi}
