| Summary: | Periodically, long span bridges require constant
structural assessment and continuous monitoring. Recently,
existed bridges and vehicles loading mechanism have influenced
many studies to predicate the dynamic bridge response and
monitor damage occurrence. The objective of present study is set
to monitor the Penang (I) Bridge using finite element model to
verify the positioning of sensors. 3D model was developed to
evaluate the modal parameter’s momentous attitude alteration of
the bridge selected grid points and elements. Discussion is
focused upon the output parameters such as displacements and
stresses generated by vehicles weights. Three types of vehicles
were chosen for the purpose of crossing the bridge. In conclusion,
from the six lanes of the bridge, high displacements were obtained
at the lane 6 (the most left or right side lane) due to vehicles loads
at the grid points while maximal stresses were enhanced at lane 6
and 4 (either of the two middle lanes) of the chosen girder beam at
bridge spans and cable elements of the infrastructure.
Subsequently, sensors were positioned at the grid points in lane 6
and elements located at both lanes due to the mixed loading
events |
