Study Notes

Structural Elements and Loads

Arches serve as both beams and columns, distributing loads efficiently.
Axial load refers to the force acting through the centroid of a construction section, perpendicular to its plane.
A column generates compressive forces along a straight path, essential for structural support.

Construction Components

A bar joist is a lightweight steel truss used primarily for support in flooring systems.
A beam transmits forces that act perpendicular to it, transferring loads to reaction points.
Bents comprise lines of columns aligned in any direction to form structural frameworks.
Braced frames utilize diagonal members for additional stability against lateral forces like wind and earthquakes.

Masonry and Wall Types

A brick and block composite wall integrates an exterior layer of brick with an inner layer of concrete masonry units (CMU) for durability.
Cavity or hollow walls consist of two masonry wythes with a space in between for drainage or insulation purposes.
Buttresses are masonry structures added against walls to enhance strength, particularly where heavy loads are applied by arches or vaults.

Load and Thermal Considerations

British thermal unit (Btu) measures heat energy; it represents the energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
Caloric value is quantified in Btu, indicating the heat necessary for temperature changes in water.

Structural Design Concepts

A built-up girder is constructed from steel plates and angles, differing from standard rolled sections due to its assembly method.
Camber refers to the intentional upward curvature provided in beams to counteract deflection under load.
Cantilever beams are uniquely supported only at one end, allowing for overhanging structures without additional support.

Truss Components

Chords are the outer structural members of a truss, while the inner web members provide stability and load distribution.
Cantilevered structures depend on cantilevers for support, highlighting the importance of effective load management.

Geometry and Stability

The centroid indicates the center of mass within a structure, crucial for balancing under gravitational influences.
