A full-scale instrumented experimental low-rise building was built and implemented to monitor wind effects on the building during typhoons. Field measurements of the near-surface wind velocity field and wind-induced pressures on the low-rise building were carried out during the passages of 10 typhoons in 2008-2011. This paper presents a combined study of field measurements and wind tunnel testing. Detailed analysis of the measured data has been conducted to investigate the typhoon-generated wind characteristics and wind-induced pressures on the roof of the experimental building under extreme wind conditions during typhoon landfalls. On the other hand, wind tunnel experiments have been performed to study the wind loads on the low-rise building. The model test results were compared with the full-scale measurements to evaluate the accuracy of the model test results and the adequacy of the techniques used in the wind tunnel tests. It was found that the wind tunnel tests underestimated the real fluctuating and negative peak pressure coefficients on a roof corner zone for quartering winds.

“…A pressure tubing system with the antirain function was used to convey the wind‐induced pressures on building cladding to a pressure transducer. Detailed description about the tubing system can be found elsewhere . The magnitude of the transfer function of the tube system was close to unity (±5% error), and the phase response was linear up to approximately 30 Hz.…”

“…Several papers have been published, which reported the analyzed results of the measurements from these three full‐scale facilities during various tropical cyclones with different strength or explored specific topics. For example, Li et al investigated the wind characteristics and wind‐induced pressures on the flat‐roofed experimental building during Typhoon Chanthu. Then, Li and Hu performed a comparative study between the field measurements of the wind pressures on the flat‐roofed building during 10 tropical cyclones and the wind tunnel experimental results from the building model.…”

A field monitoring program on an experimental low-rise building with gable roof has been established and implemented at a typhoon-prone area in China. This paper presents the field measurements obtained during two tropical cyclones in 2009. The characteristics of near-ground winds during the tropical cyclones are reported and discussed, including wind velocity spectra and profiles of mean wind speed, turbulence intensity, and turbulence integral length scale. This paper focuses on analysis of the external surface pressures measured on the central cross section of the gable roof for winds normal to the ridgeline. Pressure coefficients, probability density functions, and power spectra of the measured wind pressures are analyzed in detail. In addition, wind tunnel experiment of pressure measurements on a 1:50-scaled model of the experimental building is conducted. Comparison of the field measurements and the model test results is then performed. The paper aims to provide reliable fullscale measurements for further understanding of wind pressures on the roof of a typical low-rise building during tropical cyclones and as benchmarks for comparisons with wind tunnel experimental and numerical simulation results.

“…In response to the need mentioned above, a full‐scale experimental low‐rise building, with installation of numerous pressure transducers and a meteorological tower, has been built and located at a tropical cyclone‐prone region to observe the surface layer winds and wind pressures on the building during windstorms since 2007 . This paper focuses on the investigations of wind effects on the instrumented building during the landfall of a severe tropical storm Rumbia in 2013, including the wind characteristics near ground and the exterior pressures on the roof surface of the experimental building.…”

Summary Tropical cyclone‐induced disasters cause significant economic losses and heavy causalities every year. Most of the casualties were caused by low‐rise buildings collapsing. This study aims to investigate the characteristics of tropical cyclone‐generated winds and evaluate the wind effects on a typical low‐rise building under tropical cyclone conditions through field measurements. In‐situ monitoring was conducted on a full‐scale low‐rise building during the landfall of severe tropical storm Rumbia in 2013. Both the wind velocity field around and the surface pressures on the building were recorded during the storm. Characteristics of wind velocity field near ground during the windstorm were analyzed and compared with the specifications in the load code of China. Furthermore, when the wind approached in oblique directions, the windward roof corner suffered from the worst suctions under conical vortex. It was found that the maximum shape factors under the oblique winds were significantly larger than those specified in the load code. Moreover, probability density distributions of surface pressures induced by conical vortex were found to deviate from the Gaussian distribution. The outcomes of this study are expected to be of practical and imperative use to the wind‐resistant design of low‐rise buildings in tropical cyclone‐prone regions.
