The waffle slab floor system has several advantages: Better for buildings that require less vibrations – this is managed by the two way joist reinforcements that form the grid. Bigger spans can be achieved with less material, being more economical and environmentally friendly; Some people find the waffle pattern aesthetically pleasing [4]
Gable (ridged, dual-pitched, peaked, saddle, pack-saddle, saddleback, [5] span roof [6]): A simple roof design shaped like an inverted V. Cross gabled: The result of joining two or more gabled roof sections together, forming a T or L shape for the simplest forms, or any number of more complex shapes.
They are designed as simple spans supporting equally spaced concentrated loads for a floor or roof system. These concentrated loads are considered to act at the panel points of the Joist Girders. These members have been standardized for depths from 20 to 120 inches (510 to 3,050 mm), and spans to 120 feet (37,000 mm).

The Precast/Prestressed Concrete Institute (PCI) published the double tee load capacity calculation (load tables) for the first time in the PCI Design Handbook in 1971. The load tables use the code to identify double tee span type by using the width in feet, followed by "DT", followed by depth in inches, for example, 4DT14 is for 4-foot (1.2 m ...
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
A more recent design is the installation of a roof deck with foil-backed foam along with a second deck that is air-gapped away from the foil-backed foam to allow air to flow vertically to a ventilation outlet at the peak of the roof—it is a double-deck design with an air gap. This design improves efficiency. [13]
Laminated veneer lumber detail. Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives.It is typically used for headers, beams, rimboard, and edge-forming material.
