Flitch beam span tables

Specification FLITCH BEAM Description The GANG-NAIL FLITCH BEAM is a composite beam formed with a steel plate sandwiched between timber. The beam is manufactured with shot fired nails, fired through the timber into the steel. Bolting of Flitch Plates Adequate bolting is crucial to the perfor-mance of flitch plate beams.

Since the load is applied to this composite beam through the wood side pieces, the bolts must distribute that portion of the load that the steel plates will be carrying. At the beam end bearing supports, only. Problems with solution include having to chop a lot into the existing ceiling and room below to put in the beam and a couple headers and a new footing and post. Stronger flitch plate headers (the original engineered lumber) Pre-fabbed Sandwich Plate System Requires No Assembly. Quick and easy with no furring.

Less expensive than building it yourself. Custom cut to your length. Most beams shipped in hours. Accurate Flitch Beam Design Made Easier with Software.

Roof load: No roof load is transmitted to the beam in the family room. Flitch beams are a common type of composite construction. Click on the appropriate beam , this will take you to the calculation table for your project. These tables are ideal for professionals who will apply the required technical knowledge. For the Size Selection Tables , the user must determine the required load conditions, clear opening, and span of the trusses or other members framing into the header or beam.

FULL version: Flitch Beam Design Spreadsheet to BS (). Single-User or Company License, which one is the best for me? Fully working version where you change the company information and logo in the top left corner. Also you can change beam span. StruCalc allows for flitch beams with up to three steel plates and five solid sawn or structural composite lumber plies.

The depth of the steel plate is set at the depth of the solid sawn or structural composite member. When designing a multi- span flitch beam StruCalc does require that the top of the beam be fully braced to resist lateral buckling. Pryda Flitch Beams comprise timber beams made of commonly available timber sizes which sandwich a or 10mm steel flat. The layers are joined together using powder actuated drive pins to make up a beam capable of longer spans than the equivalent sized timber beam. Flitch Plate Beams A flitch plate beam consists of a steel platesandwiched between two pieces of lumber.

Fabrication The basic fastener spacing for each web thickness is given in the table below. I would agree with that, where your flitch beam extends over the support. Make sure you have adequate number of bolts over the support to transfer all the shear from the steel to the wood. If your support is small, say 4xpost, and your beam shallow, you may not be able to achieve the required load transfer. Span Tables for Joists and Rafters (Figure 5) gives a required compression value of 2psi for a span of feet and bearing length of 1. Select the correct table for the supported floor joist condition (simple or continuous — see notes below).

Choose the required center-to-center span for the beam in the Span column. Includes span tables for all load bearing locations and the number of jack studs. These charts are for pound per square foot snow load on the roof.

Building Code of Canada for Limit States Design and assume a normal. Joist CONTINUOUS FLOOR JOISTS SIMPLE- SPAN FLOOR JOISTS. The span tables I have looked at are for ridge beams , Floor joists, or load bearing end walls. The flitch I am looking at just has to hold up the ceiling joists and the drywall. It may be oversized already, except for the flitch over the doorway.

SuperBeam checks flitch beam that use a S2(Grade 43) steel plate flanked on either side by timbers bolted to each other through the plate. Mechanical properties of composite timber flitch beams laminated vertically with fibre reinforced plastic and steel reinforcements. A flitch beam consists of two pieces of wood with a steel plate sandwiched between them. There seems to be something missing from the table.

For flitch plates this is a good set of tables ;. Figure 5: Bending moment capacity variations of Kerto S LVL flitch beam over 1. Figure 4: EI Value variations of Cflitch beam over 1. I have read thru most of the posts on flitch beams , steel plate attached to wood beams. The advantage of this design is the greatly reduced weight of individual bars and ease of handling compared with a solid steel flitch plate (on a typical metre span a flitch plate could weigh 3kgs). The column current holds up a triple 2xbeam.
