Little did we knowwhen we introduced our first holdown

in 1966 that our product innovations

would lead us to solutions that can

help hold together five-story buildings

during an earthquake or allow builders

to install larger window and door

openings in homes. Our offering of

lateral-force resisting systems, includ-

ing Wood and Steel Strong-Wall

shearwalls, Anchor Tiedown Systems

and new Strong Frame moment

frames, gives designers and engineers

added design flexibility in wood-frame

construction and the confidence that

almost anything is possible.

At Simpson Strong-Tie, we believe that

strength really does come in numbers.

By offering the largest selection of lab

and field-tested lateral-force resist-

ing systems along with dedicated

engineers and field support reps to

back them up, you can count on the

strength of our products and our

people to perform.

Whether youre designing or build-

ing a single-family home, a six-story

mixed-used building or a retail store,

we know we have a solution to fit your

project and meet the most stringent

code requirements. And were not

done yet. The research, testing and

structural system technology thats

to come has us just as excited as we

were when we developed that first

holdown. With each new product and

design innovation, were working with

the industry to increase the structural

safety of homes and buildings around

the country. And in light of all the

hurricanes and earthquakes weve

experienced during the last 40 years,

thats a pretty good feeling.

WIND EFFECTS

High Wind-Resistant Construction

Wind forces are generated from natural events like thunderstorms, hurricanes and tornadoes.These winds create forces that attack the integrity of a structure in multiple ways: vertically,resulting in uplift forces, and horizontally, resulting in overturning, sliding and racking forces.Without proper design and construction, these forces can produce structural damageand even destruction. Modern design and construction practices, such as structuralconnectors used in a continuous load pathtransfer system, can effectively resist

these forces by reinforcing the structure from the roof to the foundation.

When the structure is anchored inplace to limit racking or sliding, thelateral force of the wind causes thestructure to rotate or overturn.

When wind flows over the roof ofthe structure, creating a strong liftingforce on the roof which can cause

it to break away.

When wind blows against the side ofthe structure exerting a lateral forcethat causes it to lean over (rack) toone side.

When wind blows against the sideof the structure exerting a lateralforce, causing it to slide off of itsfoundation.
