Floor Trusses JLC OnlineStructurally, an open-web floor truss resembles an I-beam in that it puts most of its material along its top and bottom edges where stresses are greatest. To strengthen a truss, the fabricator may double its top and bottom chords, make side-by-side girder trusses, use larger truss plates or stronger wood, or use some combination of these
Steel Joists & Joist Girders Open web-steel joists are an engineered, truss-like construction component used to support loads over short and long spans alike. Typically used in non-residential construction, steel joists and joist girders provide an economical system for supporting floors and roofs.
Long-span beams - SteelConstructionfoThe design of long span steel and (steel-concrete) composite beams is generally carried out in accordance with BS 5950, BS EN 1993 or BS EN 1994. For some types of beam this codified guidance is complemented by specific design guidance, such as that on the design of beams with large web openings (see SCI P355 ), or manufacturers' information.
Manufacturer Steel Bar Truss Girder Slab Decking Sheet Reinforced truss floor bearing plate system is a combined formwork that uses the advanced equipment in the factory to process the steel bars in the factory into reinforced trusses, and welds the reinforced trusses and galvanized profiled steel plates into one. It is a series of standardized products manufactured in factories.
The PROKON suite includes a series of modules for designing concrete elements:* Reinforced concrete beams and slabs. * Prestressed concrete beams and slabs. * Rectangular and circular columns, and also columns with any general shape. * Retaining walls. * Rectangular bases. * Design of beam and slab sections for flexure, shear and torsion.
Reinforcing Structural Wooden Beams HunkerIn this method, a steel plate is sandwiched between two identical wooden beams and the beam-and-steel sandwich is bolted together. The steel plate should be as long as the beam, with bolt holes punched or drilled through the steel. Half-inch carriage bolts are spaced 16 inches apart, with two bolts at the end of the beam. The end bolts should

Superstructure GuidelinesSteel beams come in 2 different options:Rolled Beams and Welded Plate Girders. Rolled beams are typically used for bridge spans up to 120 long. Rolled beams may be difficult to obtain in lengths over 90. Welded plate girders are typically used for spans up to 350 (in a constant depth) and haunches would be used for spans over 350.

Which is the better building material? Concrete or steel?Jun 01, 2005 · Insurance companies also report that owners and developers of a Class-A, cast-in-place reinforced concrete-framed office tower with a concrete core and wider egress stairs will save nearly 25 percent annually on the cost of property insurance. Steel:The big news in development is the price of steel.
Precast Prestressed Concrete Truss-Girder for Roof
- AbstractIntroductionDevelopment of The Proposed SystemExperimental InvestigationConclusions and RecommendationsAcknowledgmentsSteel trusses are the most popular system for supporting long-span roofs in commercial buildings, such as warehouses and aircraft hangars. There are several advantages of steel trusses, such as lightweight, ease of handling and erection, and geometric flexibility. However, they have some drawbacks, such as high material and maintenance cost, and low fire resistance. In this paper, a precast concrete truss is proposed as an alternative to steel trusses for spans up to 48m (160ft) without intermediate supports.
