Questions and Answers

Match the types of building collapses with their descriptions:

90-degree wall collapse = A collapse in which an entire wall fails as one unit. A-frame floor collapse = A collapse in which one end of the collapsed floor is supported by an interior wall. Global (total) collapse = Results in the complete failure of the building. Pancake collapse = A collapse of a building’s floors in a pancake stack fashion.

Match the types of floor collapses with their characteristics:

Lean-to-floor collapse = A collapse of a building’s floor in which one end is still supported. Cantilever floor collapse = A collapse in which one end of the floor is unsupported. Partial collapse = A failure of a portion of a building without total loss. Inward outward collapse = A collapse with the exterior wall failing horizontally.

Match the types of structural failures with the patterns of collapse:

Progressive collapse = Extensive failure initiated by local damage. Secondary collapse = An additional collapse that occurs after the initial one. Curtain wall collapse = The wall falls straight down like a curtain. Lean over collapse = Characterized by a building leaning into adjacent structures.

Match the collapse types with their implications:

Global (total) collapse = Complete failure of the entire structure. Partial collapse = Can be as deadly as a global collapse. A-frame floor collapse = Creates two void spaces. Pancake collapse = Floors lay flat on top of each other. Signup and view all the answers

Match the collapse descriptions to their types:

Curtain wall collapse = Often associated with brick veneer non-load-bearing walls. Lean over collapse = A wooden building shifts and leans. Inward outward collapse = The top portion fails inward while the bottom fails outward. SQL collapse = Does not fit but illustrates a common error in structure terminology.

Match the collapses with the structure types they commonly relate to:

A-frame floor collapse = Typically occurs in multi-story structures. Lean over collapse = Limited to wood-frame structures. Pancake collapse = Can occur in any type of multi-level building. Global (total) collapse = Affects all types of structures equally. Signup and view all the answers

90-degree wall collapse = Entire wall fails as one unit. Cantilever floor collapse = One end of the floor unsupported. Progressive collapse = Chain reaction of failures. Inward outward collapse = Exterior wall fails horizontally. Signup and view all the answers

Match each type of collapse with its potential outcome:

Secondary collapse = Occurs after the initial failure. Progressive collapse = Initiated by local structural damage. Lean-to-floor collapse = Creates a triangular void space. Curtain wall collapse = Wall falls straight down, typically affecting external aesthetics. Signup and view all the answers

Study Notes

Types of Building Collapses

90-Degree Wall Collapse: Entire wall fails uniformly as a single unit.
A-Frame Floor Collapse: One end of the floor rests on an interior wall, creating two void spaces.
Cantilever Floor Collapse: One side of the floor remains supported while the opposite side is unsupported, leading to potential voids.
Curtain Wall Collapse: Common with brick veneer walls; the wall falls downward like a curtain.
Global (Total) Collapse: Full structural failure of the entire building.
Inward-Outward Collapse: Exterior wall fails horizontally while the interior wall folds, creating inward failure at the top and outward failure on the bottom.
Lean Over Collapse: Found in wood-frame structures; upper levels lean into adjacent buildings or collapse entirely to the side.
Lean-To-Floor Collapse: One end of a floor remains supported, creating a triangular void space due to the failure of another end.
Pancake Collapse: Floors and roof collapse in a layered manner, stacking flat on top of each other.
Partial Collapse: A section of the building fails without causing a total structural failure, yet can be as hazardous as a complete collapse.
Progressive Collapse: Local damage triggers widespread structural failure through a sequence of connected failures.
Secondary Collapse: Occurs after the initial collapse; additional structural failures result from shifting loads post-primary collapse.
Situational Awareness: Refers to understanding environmental conditions in firefighting: spatial perception, comprehension of observations, and predicting outcomes of changes.
V-Shaped Floor Collapse: Floor fails near the center, with unfailed perimeter support, creating two distinct void areas.
