Study Notes

Structural Elements and Their Functions

Arches: Serve as a combination of beams and columns, transferring loads horizontally and vertically.
Beam: A structural member that carries loads perpendicular to its length, transmitting forces to support points.
Column: A vertical element designed to carry compressive loads, essential for structural integrity.

Load Types and Effects

Axial Load: A load that is applied directly through the centroid of a section, acting perpendicular to the section’s plane.
Dead Load: Refers to the static weight of a structure, encompassing all permanent components like walls, roofs, and built-in features.
Concentrated Load: A load applied to a small area, contrasting with distributed loads that are spread over larger surfaces.
Impact Load: The force applied to a structure due to moving loads, often relevant in assessing physical integrity under dynamic conditions.

Structural Systems and Components

Braced Frame: Utilizes diagonal members for resistance against lateral forces such as wind and earthquakes, enhancing stability.
Cantilever: A beam anchored at one end, extending outward without support on the opposite side.
Joist and Bar Joist: Lightweight trusses used to support floors and ceilings, crucial in modern construction.

Materials and Walls

Composite Wall: Constructed from different masonry materials that work together to handle loads effectively.
Cavity or Hollow Wall: Consists of two wythes separated by an insulating space, promoting drainage and reducing moisture intrusion.
Brick and Block Composite Wall: Features an outer layer of brick connected to an inner layer of concrete masonry units (CMUs).

Engineering Considerations

Foundation: The critical base of a structure that transmits loads from the superstructure into the ground.
Flitch Plate Girder: Combines steel and wood to create a strong, hybrid support beam system.
Gravity Connection: Utilizes the building's weight for stability, relying on gravity for structural integrity.

Fire Safety and Resistance

Fire Wall: Designed to prevent fire spread between connected structures, possessing specific fire-resistive ratings.
Fire Resistance: Refers to a material's ability to withstand ignition and thermal effects associated with fires.

Additional Technical Terms

K-P bracing: A bracing pattern resembling the letter "K" to enhance structural integrity between columns.
Gang Nail: Also known as a gusset plate, used to connect wood truss components.
Hurricane Bracing: Structural elements designed to prevent uplift during severe weather, emphasizing the importance of connection strength.

Measurement Units

Btu (British Thermal Unit): Measures heat required to raise the temperature of one pound of water by 1°F.
Kilojoule (kJ): A metric unit of energy, closely equivalent to one Btu, used in various engineering contexts.
KIP: A unit of force equal to 1000 pounds, commonly found in civil engineering calculations.

Miscellaneous Concepts

Camber: An upward curvature introduced in beams or trusses to counteract deflection under load.
Deflection: The degree to which a structural element bends under applied loads, critical for assessing functionality and safety.
Cross Wall: A wall built at right angles to primary walls, contributing to structural bracing capabilities.
