Beam columns support loads on a beam above by transferring them to the foundation. They have been used since ancient times, with modern skyscrapers relying on steel beam columns. Different materials and shapes can be used, and structural engineers use mathematical formulas to design them. Special beam-column connections are used, and failure can result in […]
Concrete columns can be decorative or structural, and their size and shape depend on their purpose. They can be used in buildings and structures, and are versatile due to their ability to be molded into different shapes. Architects and engineers determine the design of concrete columns based on the physics of the building, and incorrect […]
An identity column assigns a unique value to a database table column, but it’s not inherently unique. It requires a seed and an increment, and can cause data gaps when information is deleted. The administrator must note the numbers already in use to avoid errors. An identity column is used in database management to add […]
Lally columns are adjustable steel columns used to support building elements. They can be adjusted by unscrewing the top plate or using telescopic internal elements. They are cheap and efficient for temporary support during construction or structural work. The term comes from John Lally who used concrete-filled steel cylinders as supports in the late 1800s. […]
The water column is a hypothetical section of water from the surface to the bottom, including sludge and sediment. It is used in environmental science to study organisms, pollution, and features at different depths. Conditions change with depth, affecting the types of organisms found. The water column can change due to climatic conditions, and problems […]
Short columns are structural members that are unlikely to fail in compression if loaded uniformly along their axis. They can be made of various materials and have different lengths. Short columns are stiffer and more susceptible to damage during an earthquake. They can fail by buckling and are designed with a margin of safety. Short […]
Composite columns combine two materials or design elements, such as the Corinthian and Ionic orders in classical architecture, or a steel core and concrete in modern engineering. The latter offers increased strength, corrosion protection, and easier construction, making it a popular choice for large-scale projects. A type of column that incorporates two materials or design […]
