VERSA-LAM, ALLJOIST and BCI Joists must be wrapped, covered and stored off of the ground on stickers at all times prior to installation. VERSA-LAM, ALLJOIST and BCI Joists are intended only for applications that assure no exposure to weather or the elements and an environment that is free from moisture from any source, or any pest, organism or substance which degrades or damages wood or glue bonds. Failure to correctly store, use or install VERSA-LAM, ALLJOIST, and BCI Joist in accordance with this Installation Guide will void the limited warranty. DO NOT Do not cut, notch or drill flanges (except in roof details, see p.5 of the ALLJOIST Specifier Guide) and do not cut flanges and web. Do not birdsmouth cut in bottom flange at high end of rafter. Minimum distance Do not cut holes near bearing support ( see hole cutting chart at pp.4 and 5 of the ALLJOIST Specifier Guide for allowable distance ). Do not hang joist by top flange or web. Do not bevel cut joist beyond face of wall.

Recommendations for Higher Floor Performance An increase in floor stiffness will reduce the deflection caused by service loads.

Minimum Criteria Improved Performance Using a live load deformation of L/48 Using a thicker subfloor, hence boosting the performance of the assembly.

Installing gypsum board to increase the weight and the rigidity of the assembly. To increase the rigidity of the assembly, add x strapping and bridging at mid-span.

3 Recommendations for Higher Floor Performance An increase in floor stiffness will reduce the deflection caused by service loads. Also, the type of subfloor, and the addition of bridging and other components, such as gypsum board, will increase the rigidity of the assembly. Minimum Criteria Improved Performance Using a live load deformation of L/48 Using a thicker subfloor, hence boosting the performance of the assembly. Gluing the subfloor to increase the stiffness of the assembly and reduce deformation. Using a wide-flange product, i.e. a x 4 instead of a x, to reduce deflection. Installing gypsum board to increase the weight and the rigidity of the assembly. To increase the rigidity of the assembly, add x strapping and bridging at mid-span. Floor performance can be improved by: Reducing the spacing or using a deeper joist, will also reduce deformation and increase load sharing, there by enhancing floor performance. Adding the weight of concrete toppings is another way of ensuring a high performance floor assembly. Using non load-bearing walls will also reduce the propagation of shock waves and boost floor performance. However, the contribution of non-bearing walls is difficult to quantify. Each additional component increases the capacity of the floor to perform well under a dynamic load. By including those installation tips to increase floor performance in relation with consumer needs, you will ensure home owner satisfaction. Bridging Use ALLJOIST for bridging at mid-span. Toe nail bridging at each end using " (8d) nail on each side of top and bottom flanges. 6A Use x strapping directly under bridging in order to optimize the floor performance. Nail strapping at each joist intersection and at mid-bridging with " (6d) nails.

4 Maximum Floor Spans Simple Spans Allowable Stress Design % Load Duration Glued & Nailed Subfloor Minimum Code Criteria L/6 Live Load Improved Performance L/48 Live Load. Spans are for simply supported spans.. Minimum end bearing length is ", except for bold spans which are " bearing length.. Maximum spans are measured in between the supports (clear span) and are based on uniformly loaded joists. 4. Total load deflection is limited to L/4. 5. Allowable spans take into consideration the composite effect from the glued and nailed subfloor for deflection purposes only. 6. The adhesives used should be approved for Field-gluing Plywood to Lumber Framing for Floor Systems. Apply per manufacturer s written instructions. 7. This table was designed to apply to a broad range of applications. It may be possible to exceed the limitations of this table by analyzing a specific application with the BC CALC software.
