Stability and robustness of a structure
Stability and robustness of a structure
(OP)
What is meant by stability and robustness of a structure?
From what i have read, stability means maintaining the equilibrium position of a structure even under the action of an external force. Stability must be provided into two orthogonal directions to resist lateral forces such as wind loads, earthquake and horizontal components sue to soil load. Stability can be achieved by providing shear walls, lift shafts and rigid frames. To investigate the stability of a structure, the structure should be analysed with the maximum wind loading and minimum dead.
By robustness, it is meant that all structural members should be tied together to ensure that collapse of a small part of the structure will not cause collapse of the whole structure. This is achieved by using peripheral ties, internal ties, horizontal ties to walls and columns and vertical ties.
What is the difference between the different ties stated above?...thanks

RE: Stability and robustness of a structure
a robust structure would be indeterminate (hyper-static) because it would have redundant loadpaths (that can fail and the strcuture can still carry the required loads).
don't understand "What is the difference between the different ties stated above?" ... i see ties only mentioned in the robustness description (so why "difference" ?)

Peripheral tie: continuous chord around perimeter of floor plate
Internal tie: ties around perimeter of slab openings
Horizontal ties: ties across each floor plate
Vertical ties: Continuous vertical ties (columns) for the structure
