Design

A complex roof with multiple arcing panels provided design challenges both before and during construction.

One analytical tool that can help you consistently determine code compliance and reliable performance is the freely available wall calculator developed by the Applied Building Technology Group (ABTG). 

Since FRTW studs are allowed in wall assemblies that are otherwise defined as non-combustible, building and truss designers often confront the question does a joint between the wall and the roof or floor assembly mean that those elements of the building also require noncombustible material, like FRTW? To answer this, we need to study the IBC

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.

Corrosion resistance is critical to ensuring connector plates hold up in adverse environments. 

When Mandere Construction couldn’t get the trusses it needed to frame its projects, owner John Mandere went looking for the best truss folks he could find—and hired them
