Sažetak

In urban building groups, low-rise buildings often show a clustered layout and are often severely damaged in wind disasters due to their lack of wind resistance. However, using spoilers can significantly improve the ability of such houses to withstand substantial wind damage, ensure the safety of their life cycle, and effectively reduce wind disasters. Therefore, adopting spoiler measures has vital practical significance and broad application prospects. The influence of spoilers on the roof wind load characteristics of low-rise buildings is studied using the CFD numerical simulation method. The law and mechanism of the influence of different building densities, different layouts of spoilers, and different wind directions on the roof wind load characteristics of low-rise buildings are discussed, and the engineering application suggestions of spoilers in low-rise buildings are proposed. The results indicate that: firstly, when CA = 0.3, after the spoiler is set, the difference of the overall wind pressure coefficient of the roof is positive, indicating that the spoiler reduces the wind pressure in the area, which is conducive to the wind resistance of the roof. Secondly, in the group of low-rise buildings with spoilers, the condition of all spoilers is the most favourable for reducing the roof wind pressure of the group of low-rise buildings, followed by the setting of spoilers for the windward area. Thirdly, when CA = 0.3, after the spoiler is set, the scale of the leeward vortex of the rear buildings decreases compared with the group of low-rise buildings without spoiler, the wind speed in the area around the building group gradually increases, and the negative pressure area value and range increase significantly. This study provides a reference for low-rise buildings' aerodynamic wind resistance design and has important guiding significance.
