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. |

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. |

Gypsum Joint Ridging and Cracking Drywall cracking and ridging are typical problems seen in ceilings and walls of homes. Sometimes, both of these issues appear at the same location, with cracking appearing in wetter months and ridging in drier months. This problem has become more widespread as homeowners insist on larger rooms and open floor plans that have large clear span areas. This Research Report evaluates local environment changes that play a significant role in every gypsum ridging and cracking case. |
