For additional explanations on using these tables, refer to the respective handbook editions. If thus required, use Class S (HPC) concrete. To use the beam span calculator below, first select the number of floors that the floor beam will be supporting from the drop-down list. In the table above, the widest floor beam span for 12' of supported floor joists is 14'7" (if using a 5-ply 2 X 12). For our example above, we are using a 4-ply 2 X 12. Longer spans are generally done with composite steel concrete or only steel structures. This support could take the form of a structural wall. This means that our 4-ply 2 X 12 will be 4 X 1-1/2 inches wide or 6 inches. In general, wood columns are spaced every 8 to 10 feet depending on the strength of the floor beam above it and the load on this beam.

The species of lumber, size of lumber and the load it carries. If built-up wood posts are being used, the width of the post needs to be as wide as the beam that it is supporting. Therefore a post to support this built-up floor beam will need to be 6" by 6". The full table shows more lumber sizes. Let's expand our house beyond that 17'2" span capability to 24 feet wide. The question now is how big does that center floor beam need to be? They are produced to a concrete … 1978) [ACI 318-77, UBC-76], Precast, Prestressed Solid Wall Panels (31k, PDF), Precast, Reinforced Solid Wall Panels (31k, PDF), AASHTO Girders (Type II, III, and IV) (34k, PDF), PCI Design Handbook (3rd Ed. UDL means uniformly distributed load which is measured in kiloNewtons per metre (kN/m). Supreme Floor Beams are 155 mm deep and are manufactured in two widths; 120mm and 170mm wide respectively and in the same profile. Use the span tables below to determine allowable lengths of joists and rafters, based on size and standard design loads. Data taken from CMHC Wood-Frame House Construction Tables Please note that the 170mm wide floor beams are only available in lengths over 4000mm. Whenever span-to-depth ratio exceeds 30 for double tees a positive roof slope is essential to preclude ponding. Beam Span Chart Table The span of a beam is dependent on a few variables. This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12). It also shows the maximum that the beam can span for various numbers of such pieces of lumber built together (this is indicated by 3-ply, 4-ply and 5-ply). In the case of our example house, the house is 24 feet wide so the house will require a total width of 24 feet of joists. For example, for a 24 foot wide house with a center floor beam, the total supported length of the floor joist is 24 feet.

Dividing by two gives us 12 feet of supported length. VERSA-LAM ® laminated veneer lumber (LVL) beams and headers eliminate twisting, shrinking and splitting, and deliver flatter, quieter floors and structures. The following sections from the PCI Design Handbook include interaction curves, load tables, and section properties for various precast concrete components. Then you divide this by two to give a supported length of 12 feet. ... Load / Span Charts for 155mm deep beams at varying centres. The table below gives the maximum span for each precast concrete 225mm T beams based on using Thomas Armstrong Concrete Blocks products. With 100mm thick blocks (max density = 1900 kg/m3) For additional explanations on using these tables, refer to the respective handbook editions. Typically in basements, these posts will be structural steel, concrete or built up wood posts made from pieces of standard dimensional lumber (2 "bys") all nailed together side by side. The supported length shown along the left-most side of the table, is the total length of the floor joists to be supported on either side of the floor beam divided by two. (1) and9.20.17.4. The floor joists are still 12' long but now you can see a floor beam running horizontally across the middle of the house (supported by the lower concrete foundation wall). Width of beam ≈ (0.4 to 0.6) × depth. This site also has information on learning how to read joist tables and a joist calculator. Although the ductility energy ratio ( $$\\mu_{E}$$ μ E ) of the reinforced concrete beam has been the topic of numerous study purposes and critical inquiry for the last decades, narrow consideration, especially in terms of reinforced concrete deep beams (RCDBs), is conducted to examine the ductility energy of hybrid-RC deep beams with various CFRP configurations. For now, we'll look into supporting the floor joists with a floor joist beam.
