Interior Architecture and Structural Engineering working with existing buildings
Basic structural requirements
Mustn’t collapse. Strength, stability, robustness
Must be serviceable. Stiffness, durability
Must be buildable. Buildability
Load transfer mechanisms – Load paths
Each member in load path must have adequate capacity/capable of transferring
Loads – act externally to a structure, forces act within, equal to applied loads, opposite direction. Made up of members. Actions.
Tension: load/force that causes an element to shorten.
Compression: load/force causes element to shorten ??????
Shear: causes shear deformation.
Bending movement: causes element to bend.
Potential loads acting on structure: tables, people, weight of floor, beams.
Gravity (vertical) loads.
Detective work to establish/justify load paths:
How did the original designer envisage loads would be transferred.
Can they be established vertically or laterally?
Do they have sufficient capacity?
If they don’t: remedial works
What changes are you planning? Where are new load paths needed. Will existing ones remain? Does it need temporary work so doesn’t fall when making new.
Openings in structural walls
Removal of load bearing walls/columns
Creating voids in floor slabs
Inserting new floor slabs
Reversibility and readability. Old castle and new built onto.
Openings in structural walls.
Beam/lintel required to support
Pressed steel lintels
Precast concrete lintels
Cast in situ reinforced concrete beams
Stiffness is often critical
Establish headroom requirements early on
Removal of load bearing walls/columns. Consider stability if removed.
Insertation of new floor slabs.
Façade retention: construct new building frame whilst maintaining the front only.
Existing foundations may need to be underpinned.
Caroline – Tangible of Interaction
Personal engagement with heritage
Branding e.g. MoMA design store
Experience e.g. Jubilee – a view
Wayfinding (paths around)
Exhibition as a stage
Seenography. Form follows content
Atmosphere e.g. Artist Olafur Eliasson
Poetic of space. Sound, temperature, light of things, tension between interior and exterior
