Loads

A spring Wisconsin snowstorm demonstrates how a building design practice may lead to higher risk.

An unusual design project gives this CM international exposure.

Getting information up front on sprinkler systems can ease the design process.

Finding opportunity in the growing solar panel market.

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

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

A best practice for building designers: find a friend to check your load paths.

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).

I am thinking of using wood trusses for the roofing/ceiling structural systems on some houses I shall build. I remember, though, an engineer/volunteer fireman commenting back in 1989 that the connector plates are prone to expand and pop off, early on in a fire, causing catastrophic structural failure. Was this the case, and if so, has this problem been corrected?

Do you have open web floor truss span tables available?
