Study on Physical and Mechanical Properties of Historical Timber Building in Myanmar A Case Study of Pyay Hostel in Yangon University Campus ijtsrd
The assessment of existing timber structures requires the determination of the physical and mechanical properties of the individual timber members, which is often obtained by visual grading combined with information of small clear wood specimens. This study aims to investigate the properties of timber members for the seismic safety assessment and evaluation of existing timber building, Pyay Hostel situated in Yangon University. Because this building has been established in 1924, its life time is near 100 years and has some circumstances such as alteration of uses and detection of deterioration. The physical and mechanical properties of existing timber members such as moisture content, specific gravity, static bending, compression parallel to grain, compression perpendicular to grain, tension parallel to grain and shear parallel to grain are determined by experiment in the Structural Laboratory, Civil Engineering Department, YTU. According to the experimental results, it is found that the physical properties of teak and pyingado used in this building are 10 and 14 of moisture content, and 0.56 and 0.8 for specific gravity. In the mechanical properties of timber members, the modulus of elasticity values for Teak and Pyingado are obtained 2.79×106 psi and 3.88×106 psi, and the modulus of rupture values of Teak and Pyingado are 1.94×104 psi and 2.81×104 psi respectively. On the other hand, it is found that the compressive strength of Teak and Pyingado are 636.69 psi and 1210.75 psi respectively. This investigation results are reasonable and applicable to use seismic safety assessment and evaluation of existing timber building.
