Structural Strategy
Initially I began to apply a rigid grid to my building to try and form a coherent structural system. However, I found this to be too restrictive given the unusual shape of my building.
Lift core can be used to support stairs.
After conversations with a structural engineer, it was decided that a concrete column primary structure would be most suitable, given its ability to deviate from the strict grid form often necessitated by steel. In-situ cast walls which run through both floors will be used where possible to help deal with lateral wind loads. Drawing directly onto my plans as they stood helped me to see how this structure could be implemented.
Grey crosses represent possible locations for concrete columns
Additional support for stairs here needs to be given by extending the cantilever outwards.
Thickening of concrete slab here to form a beam would ensure suitable support for ramp.
Slight changes in the floor plan would ensure more adequate distribution of wind loads by providing rigid cross bracing.
Some window placement will have to change given proposed column locations.
By overlaying my plans, I was able to see where the location of these in-situ cast walls could be. Thus ensuring that my building is rigid, and can withstand external wind loads.
Lightweight covering to provide internal walls.
Steel Scaffolding
Internal temporary spaces will be free standing, supported using readily available scaffolding poles, owing to their ease of construction. This will ensure that the residents will be able to create rooms to suit their needs.
