Exterior Brick Masonry Veneer Supported by Wood Trusses Code compliant use of Metal Plate Connected Wood Trusses (MPCWT) to support brick veneer can be accomplished by both individual designs and by adhering to the recommendations that follow within this report. This discussion focuses on a common use of MPCWT’s; the gable end at the transition from a wider section of a building to a narrower section. |

Deflection Limits for Floor Trusses There are circumstances when the deflection requirements for a specific structure that utilizes floor trusses as structural members are questioned. The current residential and commercial building codes provide minimum design requirements for loads and for deflection of structural floor members, which also apply to floor trusses. The building designer may specify more stringent requirements. This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products |

Deck Ledger Attachment to Residential Wood Truss Floor Systems This Research Report provides construction details for residential deck ledger attachment to metal plate connected wood truss floor systems. Proper attachment of the deck ledger to the house is critical for ensuring that an “attached” deck is safely and securely supported at this location. |

Conventionally Framed Roofs & Roof Trusses: Code-Compliant Construction This Research Report reviews pertinent sections of the 2006, 2009 and 2012 International Residential Code (IRC), the 2012 IRC Commentary, and additional sources in an effort to compile the related data and identify discrepancies or omissions. The focus is catered toward meeting and better understanding the requirements for conventionally framed roofs and roof truss construction per IRC Section R802. |

Cantilevered Sill Plates: Use with Wood Trusses to Align with Varying Thicknesses of Exterior Sheathing The prescriptive residential energy code requirements found in the 2009, 2012 and 2015 International Residential Code (IRC) include requirements for continuous insulation at foundations in several climate zones. This Research Report discusses the issue of cantilevered sill plates supporting metal plate connected wood trusses installed parallel and perpendicular to the foundation walls where there is a potential for discontinuous planes between the exterior wall above the sill plate and the foundation insulation planes. |

Bottom Chord Live Load Concurrency and Truss Design The truss industry is currently employing ASCE as its source for the loading of live loads to the bottom chord of trusses for uninhabitable attics, in accordance with the International Residential Code and the International Building Code. However, there currently is a discrepancy between ASCE 7, the IBC and the IRC. This report examines the discrepancy and the correct loading for proper truss design. |
