The concept known as a double angle is associated with the three common trigonometric ratios: sine (sin), cosine (cos), and tangent (tan). … Therefore, doubling the angle refers to multiplying the angle by two.

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. … Many industrial and government standards exist for the production of pipe and tubing.

Fixed base columns must also be straight columns and are typically deeper at its base in comparison to pinned base. Typically fixed base columns are recessed below finished floor. The graphic of the fixed base column, to the left, is just an example of what the baseplate could look like.
The rolled steel beam sections with parallel faces of flanges are recently developed. These beam sections are called as parallel flange sections. These sections have increased moment of inertia, section modulus and radius of gyration about the weak axis. Such sections used as beams and columns have more stability.

an element of framed structures consisting of individual angle irons, channels, I-beams, and similar simple metal sections joined into a single unit by batten plates or lattices. Built-up beams are chiefly used as structural elements under compression, such as columns or chord members under compression in trusses.

Basement Walls. Basement walls and design differ from other structural walls because in the basement inside of wall have living space and earth filling on the outside of wall i.e. why these are structurally designed as retaining walls to overcome the lateral pressure of outside filling of soil/earth.
