Abstract:
Nowadays, several measurement techniques and devices have been developed to measure the deformations on structural members, such as gages, low voltage displacement transducers (LVDT), strain gages and acoustic emissions (AE). With the recent developments, the photography is now in use of science to measure the deformations via the Digital Image Processing (DIP). This research aimed to determine and compare the mid-span deflections of wooden beams that are subjected to three-point bending load. The mid-span deflections of wooden frames are collected via the comparators and DIP. The behavior of the wooden beam is also compared with numerical results generated by using finite element method (FEM). It is observed that the DIP is considerable while measuring the deformations of structural members.
