Abstract The tremendous growth in the development of tall buildings has necessitated assessment of their oppressive impact on citizens. Accordingly, this study seeks to assess the oppression caused by changes in the form of tall buildings (i.e. height, width, and height-to-width ratio) on observers at different distances. For this purpose, an assessment framework was developed based on the literature and examined through a case study with the results being compared with the criterion of permissible oppression (a visual weight of 8%) that can be endured by citizens. Finally, the accuracy of the results was evaluated by a survey of people's opinions. The findings indicated a relative correlation between the results of the framework and the participants' opinions, through there were some differences. Based on our survey, the effect of the building's height on oppression was generally more significant than that of the width. In scenarios where the height of the building was fixed, the width of 20 m was a critical point in oppression. If the building's width exceeded 20 m, the oppressive effect on citizens would significantly increase. Given a constant height, changing the height-to-width ratio from 2 to 3 was more effective in reducing oppression than altering it from 3 to 4. In conclusion, tall buildings with a height of 60 m or higher and a width of 15 m or higher on streets which are 30 m wide or narrower impose the highest oppression on the observer which can be mitigated with sufficient vegetation in front of the building.

评估高层建筑形式对市民的压迫性影响：高度、宽度和高宽比

摘要 高层建筑发展的迅猛发展需要评估它们对市民的压迫性影响。因此，本研究旨在评估不同距离观察者对高层建筑形式（即高度、宽度和高宽比）的变化所造成的压迫。为此，基于文献制定了评估框架，并通过案例研究进行了审查，并将结果与​​公民可以忍受的允许压迫标准（视觉权重为 8%）进行了比较。最后，通过民意调查来评估结果的准确性。研究结果表明框架的结果与参与者的意见之间存在相对相关性，但存在一些差异。根据我们的调查，建筑物的高度对压迫的影响通常比宽度的影响更显着。在建筑高度固定的场景中，20m的宽度是压迫的临界点。如果建筑物的宽度超过20 m，对市民的压迫感会显着增加。在高度不变的情况下，将高宽比从 2 更改为 3 比将其从 3 更改为 4 更能有效减少压迫。 总之，高度为 60 m 或更高且宽度为 15 m 的高层建筑在 30 m 宽或更窄的街道上或更高的街道上对观察者施加最大的压迫，这可以通过建筑物前面的充足植被来缓解。在建筑高度固定的场景中，20m的宽度是压迫的临界点。如果建筑物的宽度超过20 m，对市民的压迫感会显着增加。在高度不变的情况下，将高宽比从 2 更改为 3 比将其从 3 更改为 4 更能有效减少压迫。 总之，高度为 60 m 或更高且宽度为 15 m 的高层建筑在 30 m 宽或更窄的街道上或更高的街道上对观察者施加最大的压迫，这可以通过建筑物前面的充足植被来缓解。在建筑高度固定的场景中，20m的宽度是压迫的临界点。如果建筑物的宽度超过20 m，对市民的压迫感会显着增加。在高度不变的情况下，将高宽比从 2 更改为 3 比将其从 3 更改为 4 更能有效减少压迫。 总之，高度为 60 m 或更高且宽度为 15 m 的高层建筑在 30 m 宽或更窄的街道上或更高的街道上对观察者施加最大的压迫，这可以通过建筑物前面的充足植被来缓解。
