An unusual project with an uncommon shape presented the kind of design challenge truss technicians don’t see every day.
 

A family team known for launching and selling home-construction companies is rolling out its newest venture, Hanover Family Builders, with nine communities in Osceola and Lake counties.

NFC Executive Director Chris Tatge and SBCA staff member Jim Vogt demonstrated on the BCMC show floor just how quickly a structure comes together with wall panels.

When Jim’s Apple Barn, the largest candy store in Minnesota, wanted to expand by way of adding a confection-filled planetarium to the end of a blazing yellow barn already bursting with sweets, it had a difficult time finding a truss company willing to take on the project. “We were the only ones that said yes,” recalled Trevor Ebinger, a member of the Manion Lumber & Truss sales staff. “It was quite an undertaking.”

A little forethought can prevent the potential overstress that occurs when deflection leads to rooftop ponding.

The BFS design team in Shelby, Alabama “collaborate on anything that doesn’t sit right,” says Thom Patton. One result: a roof that rests perfectly on a school building after a simplified build and easy install process.

This presentation seeks to explain how to correctly apply live loads to the bottom chord of trusses for uninhabitable attics in accordance with IRC Table R301.5 and IBC Table 1607.1 and ASCE 7-10 Table 4-1.

This Research Report will look specifically at the sill plate requirements according to the 2009, 2012, and 2015 International Residential Code (IRC) and International Building Code (IBC) and clarify if a sill plate is required in the following conditions:

  • Flat truss bottom chord bearing on ICF wall.
  • Flat truss top chord bearing on ICF wall.
  • Roof truss bearing on ICF wall.

This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products where deflection requirements may impact serviceability.

Lumber Design Values

No matter the species, component manufacturers (CMs) purchase and rely on the accuracy and reliability of many different lumber design properties, including: bending (Fb); shear parallel to grain (Fv), compression perpendicular to grain (Fc^), compression parallel to grain (Fc), tension parallel to grain (Ft), and modulus of elasticity (E and Emin).
