Analysis of the structural systems of a RCCshell structure
Structurally analyze and document any one interesting case study of a concrete shell
structure located in Doha. Groups can use sketches, drawings, pictures, videos to present
their work. A small project should be selected to allow adequate review/ analysis.
Deliverables and items to consider for the research project
i. Floor plans and process sketches: Show grid system if any. Show the structural core of the steel
structure if any
ii. Structural system: general dimensions to be included in the drawings. Consider all items
described in the class
iii. Description of the structural system: For ex: How it works, how many types and levels of structural
systems are used, dimensions, span, materials and technologies used, advantages
disadvantages, etc.
iv. Scheme of the structural system: number and types of structural systems, components used and
connections
v. Scheme of load/force distribution: Legend with different colors for different materials and
loads/forces. (e.: red= tension, blue= compression, f=green membrane stress etc., or use other
colors suitable to your project)
1. Shell type
2. Form finding
3. Forms of curvature (in your design/ case studies)
4. Show free body diagram (FBD) of the steel structure members
5. Show possible forces/ load acting on the structure
6. Types of frames used
7. Frame bracing if any?
8. Shell grid if applicable
9. Compression stresses - tension stresses
10. Support systems
11. Single/ multiple systems
12. Membrane cover if applicable
13. Composition of the selected structure: state and show the structural systems is
informed by the case study
14. Show details where appropriate
15. Shell dependent/ shell independent structure
16. Active/ passive shell structure
17. Forms of curvature- rule of surface; surface of revolution; surface of translation
18. Single/ double curved
19. Developable/ undevelopable
Envelope system: Describe the fundamental performance, aesthetics, moisture transfer (if any),
durability and energy and material resources
