building form!

so trying to get a solid grasp of what my thesis is going to become -

so My thesis discusses the need for preemptive design and community development before the event of a disaster. Time and time again, in disaster recovery situations, the culture of the area and the peoples' needs are often over looked in the rush to save lives and return to normality. After a disaster we have the ability reinvent our communities for a more sustainable future, however this often isn't the case because the rules are not in place before hand. I am proposing a new civic presence in Portland could help support planning how to redevelop in case of disaster. This would be actualized as an urban resource center where people can go to find out more about their community and sustainable living, and local businesses can find support and information on emergency preparedness. Connected to this will be open park space with a local market to promote a place used regularly by the community. The program will be able to change over time and will be a central emergency aid location. The structure will be lightweight and playful and interactive, and can be resilient. The building will be able to function in a disaster situation and smaller 'pods' of the building will be located throughout the city as smaller aid locations.

the form is derived from a circle and a canopy - structurally seems to make sense, i love circles,.... the canopy is comprised of circular arches supporting a space-frame with some type of membrane roof. any suggestions
