Building vibration due to road traffic

In one case undertaken by RE, heavy-road-traffic-induced vibration caused a 5-story building to vibrate and shake. The building is located on the soft soil layer of the Chao Phraya River basin, which lowers stiffness. Also, damping amplifies the vibration.

In the testing process, real-time acceleration was monitored on each floor using accelerometers. The building was evaluated using the human comfort level, the floor acceleration guidelines and criteria as well as floor drift and building drift in general.
