“…Hiramatsu and Akagi conducted a full‐scale observation to investigate the response characteristics of lattice steel towers with square sections using angled steel and proposed expressions for response estimation to explain the along‐wind and torsional responses of the towers based on the stationary approach. Holmes et al measured the acceleration responses of a lattice communication tower in Australia and found that the along‐wind and across‐wind accelerations of the tower increased with mean wind speeds. Tamura et al also investigated the wind‐induced vibrations of a 100‐m high tower and a 77.6‐m high tower at Tokyo International Airport to study the efficiency of the tuned liquid damper during typhoons.…”

Summary Lattice towers are among the most vulnerable structures during typhoons. In this study, the wind engineering research field base near Shanghai Pudong International Airport was used to measure the mean wind speeds and directions at a height of 10 m, as well as the accelerations atop a 40‐m high lattice tower during Typhoons Neoguri and Nakri to investigate the characteristics of the near‐ground wind and the responses of the lattice tower. Moreover, an aeroelastic model of the lattice tower was generated by the discrete stiffness method. Using the wind tunnel test of the aeroelastic model, the root mean square accelerations of the tower were studied with different wind speeds and directions. The responses of the tower in the across‐wind direction were found always higher than those in the along‐wind direction, which meant the vortex shedding of each single cylinder had an impact on the responses of the tower in the across‐wind direction. The test results were compared with those of field measurements to evaluate the accuracy of the aeroelastic model, and the two were generally in a good agreement. Thus, the aeroelastic model could precisely simulate the dynamic characteristics of a prototypical lattice tower using the discrete stiffness method.

SUMMARYThis paper describes the results obtained from the full-scale measurements of wind e ects on a 70-storey building in Hong Kong. The building which has a height of approximately 370 m is the second tallest structure in Hong Kong. The ÿeld data such as wind speed, wind direction and wind-induced acceleration responses have been measured since 1995 including the close passage of two typhoons; typhoon Sally and typhoon Kent. Detailed analysis of the ÿeld data is conducted. The full-scale measurements are compared with the wind tunnel results obtained in the Boundary Layer Wind Tunnel Laboratory at Western Ontario University. The amplitude-dependent characteristics of damping and natural frequency that were obtained by using the random decrement technique are investigated.
