A stub-girder system (or stub girder system) is a model of steel frame structures consisting of beams and decking, originally developed in the early 1970s in part by Joseph Colaco of Ellisor Engineers Inc.. [1] [2] Short lengths of stub girders the same depth as the floor beams are welded to the tops of the main girders to provide a connection ...
Beam and block is a construction method to support flooring, especially for ground floors as well as multi story buildings. [1] It is made of cast concrete , one piece of which is a prestressed concrete beam , which can be an inverted T-shaped beam, or lintel, the other piece being a simple rectangular block. [ 1 ]
The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
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).
A girder (/ ˈ ɡ ɜːr d ər /) is a beam used in construction. [1] It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. Girders are commonly used to ...
Floor spans may be short bay lengths, while providing two column bay spacing for room arrangements. [1] This results in low floor-to-floor heights. Typically, an 8'-8" floor-to-floor height is achieved. [4] Columns have minimum bending moments due to gravity and wind loads, because of the cantilever action of the double-planar system of framing ...
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]
The term binding joist is sometimes used to describe beams at floor level running perpendicular to the ridge of a gable roof and joined to the intermediate posts. Joists which land on a binding joist are called bridging joists. [3] [4] A large beam in the ceiling of a room carrying joists is a summer beam. A ceiling joist may be installed flush ...
