- Abstract
In the view of the serious problem of low-rise gable roof buildings damaged by typhoon, a method of using wind-resistant energy dissipation devices on roof wind pressure to reduce the damage of strong wind on low-rise gable roof buildings is proposed in this paper. The wind tunnel experiments were carried out to study the influence of wind-resistant energy dissipation devices on the roof wind pressure. The experimental results shown that the wind-resistant energy dissipation devices can reduce the worst negative pressure over the whole roof greatly. The mean negative wind pressure coefficients over the easily damaged area on windward roofs, such as the area near the ridge, contact edge of roof and gable, can be decreased 50 percent; When the upper part of the eaves is fitted with the wind-resistant devices and deflector, the extreme value of the mean wind pressure coefficient of the measuring points is significantly reduced at any wind direction, and the reduction amplitude is up to 40%. The wind resistant effect is better than installing the wind-resistant energy dissipation devices alone or installing the deflector separately.
