At 90° wind incidence angle, buildings RE1, RE2, RE3 and RE4 are subjected to almost 22, 57, 82 and 114 % higher base moment-Mx as compared to the base moment-Mx on square building SQ1 at corresponding angle, respectively.
At 0° wind incidence angle, buildings RE1, RE2, RE3 and RE4 are subjected to 25, 40, 55 and 60%% lower base moment-Mz as compared to the corresponding base moments on square building SQ1, respectively.
Whereas at 90° wind incidence angle, buildings RE1, RE2, RE3 and RE4 are subjected to almost 25, 59, 83 and 120 % higher base shear-Vbz as compared to the corresponding base shear on square building SQ1, respectively.
At 0° wind incidence angle, buildings RE1, RE2, RE3 and RE4 are subjected to almost 27, 41, 56 and 60%% lower base shear-V bx as compared to the corresponding base shear on square building SQ1, respectively.
From yet another angle, the building looks like a huge bird that has landed on the park - and Nouvel continues the avian theme by cladding many of the outside surfaces, underfoot and on walls, with 200,000 tiles in the shape of flying birds in what must be 50 shades of grey aluminium.
In the analysis he discovered that optimum diagrid angle for building of height from 60 to 20 stories falls between 53° and 76°.
More simulations should be performed to assess the validity of the correlations in a wide range of inputs (higher roof tilt angle, other building envelopes, more lighting and appliances profiles…).
(Definition? Exterior angle of building).
From certain angles, this building is all hips.
