Implementing numerical simulation for static and dynamic loading of cable-stayed Penang Bridge
Penang (I) bridge is classified as a Cable stayed bridge, which constructed globally for their long spans and aesthetics appealing. Factors such as high traffic volumes and geometrical movements cause increase in deflections and stresses on the bridge system, which at the end these defects possibly...
