Aiming at the problem that low-rise buildings are easily damaged by typhoons, this paper presents a protection method by installing a new type of wind-resistant energy-dissipation devices on low-rise buildings.To find the optimal arrangement of proposed devices and maximizing the utility of the devices, six cases with different installing schemes were analyzed in this paper, including to install the device on the edge of the double-slope roof, the roof ridge, and installed with spoiler.The influence of energy-dissipation devices system on peak wind pressure and average wind pressure of roof were studied by wind tunnel experiments.The numerical simulations of the 6 installation cases were carried out, and the simulation results are consistent with the wind tunnel test.The optimization on the geometric parameters of energy-dissipation devices was studied, and the influences of the tip speed ratio, blade root angle and blade to tip torsion angle on the energy-dissipation coefficients were studied.The results show that the installation of energy-dissipation devices can effectively prevent the roof damage from wind.In addition, by combining the spoiler and the energy-dissipation devices at the windward side of the eave, the adverse effects of wind suction on the roof structure can be significantly reduced.The aforementioned installation method can significantly reduce the extreme value of the average wind pressure coefficient of the roof (in both windward and leeward sides) at any wind direction angle and the reduction ratio is up to 40%.
