class Component(name, limit_state=None)

Bases: object

A named component limit state within a structural system.

Parameters:

• name (str | LimitState | Callable[..., Any] | None) – Component name. For convenience, if limit_state is omitted this argument is treated as the limit-state object and the name is inferred.

• limit_state (LimitState | Callable[..., Any] | None) – Component limit-state function. Callables are wrapped in LimitState.

Notes

Component functions may use only a subset of the stochastic model variables. Extra keyword arguments are filtered unless the function accepts **kwargs.

Methods

as_limit_state	Return this component as a PySTRA LimitState.
evaluate	Evaluate the component limit state for one or more samples.
failure_mask	Return a boolean mask where the component is failed.
get_limit_state	Return this component as a PySTRA LimitState.
iter_components	Yield leaf components in this subtree.

evaluate(**kwargs)

Evaluate the component limit state for one or more samples.

Return type:

ndarray

as_limit_state()

Return this component as a PySTRA LimitState.

Return type:

LimitState

get_limit_state()

Return this component as a PySTRA LimitState.

This legacy-style alias mirrors the existing PySTRA getter naming.

Return type:

LimitState

iter_components()

Yield leaf components in this subtree.

Return type:

Iterator[Component]

property components: tuple[Component, ...]

Tuple containing this component.

failure_mask(**kwargs)

Return a boolean mask where the component is failed.

Return type:

bool | ndarray
