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.
