Structures International, LLC - Providing Simple Solutions To Complex Problems TM

Developed in response to state and national building code requirements to provide design pressures for components and cladding, Structures International offers “4WIND”, a simple and inexpensive solution to the complex calculations currently required by both the Florida Building Code 2004 and the International Building Code 2006.

These new programs have retained the same user-friendly format introduced in our previous programs, but they have been enhanced in many ways. The new “4WIND” programs have been written to be independent of other software, so Microsoft Excel is no longer required. In addition, you can now export your calculations from the “4WIND” programs into your AutoCAD drawings.

The Florida Building Code 2004 and International Building Code 2006 require the following five items be included with all construction drawings:

basic wind speed (MPH)
wind importance factor (I)
wind exposure category
internal pressure coefficients
pressures on components & cladding

While the first four items are easily determined, the fifth is not.

Calculating pressures on components and cladding is very time-consuming. The formulas and charts commonly used in calculating these values (published in the ASCE 7-05 and the building codes) require interpolation and engineering judgment to determine the values of individual coefficients to be used in the various calculations.

Structures International offers easy-to-use tools developed by licensed engineers that produce a simple report that can be imported into your drawings as part of your submittal. “4WIND”, a significant time saver that allows you to provide your clients with accurate and prompt design pressures! With these tools, you can quickly determine the impact of wind-related variables and calculate wind pressures on components and cladding using the actual equations of the curves shown in the ASCE 7-05 charts. The results are as accurate as possible and therefore require no interpolation, and ALL THIS with just a few basic input requirements for each component.
