Part 1 – Problem 06: If the retrofitting scheme includes structural dampers, do we need to provide a method of proof as to how we could have built a scaled damping members with the properties we input to the SAP model? The main problem being the confirmation that our proposed member design would have the properties we suggest.

If your retrofit scheme includes dampers, then yes, please provide information about the properties of the dampers that you input into the ETABS/SAP model and how those properties relate to dampers that could be constructed in a physical balsa wood tower and/or how the dampers are similar to dampers that are implemented in real structures. 

Part 1 – Problem 07: If we were to consider a retrofit design similar to BRBFs, is the dimension limitations specific to the member in its entirety or to each of the materials considered in the design of this member?

For any retrofits applied to the existing structure, you may deviate from the dimension limits of the Design Guide in order to simulate a real retrofit technique. When considering a BRBF-type member, you may choose to stray from the dimension limits for the entire composite member or for each of its components, but please provide […]
