Week 5 Journal: This week, we did the assignment 2’s presentation. For my roof model, there are trapeziform frames in the front and back. Also, the stable triangular frames in the both sides. Besides, I use the three removable semi-circles to cover doors and others. However, tutor thought that the semi-circles were complex because the roof should be made simple.Thus, I have to alter the structure of roof and re-make again. Next, tutor gave us the case study building to explore the structural concepts. Also, we have to draw, plan and analyse the sections of the building. It is quite interesting.
