ARCH755 Project 1

     1. Change of the surface Firstly I tried to change the surface of Canton Tower by simulating Airspace Tokyo, for which I used the Voronoi algorithm. Also I had offset the surface to generate thickness.                                                   the changed surface                the initial surface                                the changed surface 2. Shadow range analysis  Secondly I did a shadow range analysis. It could choose a specific date and analyze the intraday shadow distribution of the building. We could input the information about local meteorological parameter such as solar altitude or solar illuminance. The picture below showed the result, the different color in different area represent different illumination time in the same day.                    result of shadow range analysis                      result of shadow range analysis 3. Genetic algorithm  Lastly I tried to optimize the design by using genetic algorithm. I set the

ARCH755 PROJECT 1 Professor: Wei Yan Student: Zhenning Chang Canton Tower is also called Guangzhou new TV Tower, it is located in Guangzhou city of Haizhuqu District (Yizhou Island) ， near the Chigang tower. The main body of Guangzhou tower is 454 meters high, on the top is a 146-meter-high antenna, the total height of 600 meters. It is the tallest tower in China, the second tallest tower in the world, second only to the clear sky tower in Tokyo. The outer steel structure of Canton Tower consists of 24 vertical columns, diagonal braces and circular rings. Each column is spaced at intervals and arranged in an annular arrangement. The main body of the tower is the gradient elliptical mesh structure, Its structure is generated by the two upward rotated elliptical steel shell, one is based on the ground, another on the imaginary plane of 450 meters high, two ellipses rotate 135 degrees of each other, and the two ellipse shrink thinning in the waist. Among them, the bottom of t
