The structure itself is more complicated. To observe and contrast on the whole, it is necessary to simplify the structure and extract features for comparison. The abstract approach follows two principles:
First, to show the more obvious geometric volume in the structure; for example, this project is mainly comprised of a trapezoidal block and two cuboids. In the process of abstraction, the rear wall and the front sunshade frame are removed to retain the relationship between the trapezoidal block and two cuboids, as shown in the following figure:
Second, to embody the more obvious composition relationship in the structure. For example, this project is composed of a structural unit that appears repeatedly, so the separation between the structural units that are built on the building structure is retained in the process of abstraction, instead of the entire roof being abstracted into a roof plate, as shown in the following figure:
From the principles above, the process to abstract the structures of 112 architectural works is shown in Table 2.13.
