Wind Loads on Signs 2005:

This software performs all the wind load computations for signs in ASCE 7-98, 02 & 05, Section 6. The software allows the user to "build" sign structures within the system. It provides basic wind speeds from a built-in version of the wind speed map or allows the user to enter a wind speed. It provides for input of topographic features.  It has numerous specialty calculators.  It provides a selection list of steel pipes and tubes adequate to meet the calculated forces for defined sections of the support structure.  Wind Loads on Signs 2005 also allows the user to design a simple drilled/cylinder foundation based on UBC 1806.8.2 and IBC 1805.7.2.   


Standards Design Group, Inc., (SDG) developed this software in conjunction with Sign Industry professionals to provide sign shops with the ability to design and estimate an adequate sign structure, consistent with the International Building Code (IBC) which has recently been adopted in many jurisdictions throughout the United States.  The IBC requires calculation of wind loads and the resulting forces in a way that significantly differs from the calculations that the sign industry traditionally used.  In many cases, sign shops must submit bids or quotations for projects prior to incurring the costs of a registered professional engineer.  This program is designed to assist these sign shops in selecting structural materials that meet or exceed the engineering requirements for the defined site parameters.  Once the job has been contracted, a registered professional engineer, familiar with sign design, should be able to provide an adequate structure, consistent with the design parameters, within the material costs estimated for the job.

·         General:

o        The software operates in a Windows TM environment.

o      The software is user friendly. It allows the user to update and change parameters continuously through the process of determining wind loads for a given structure without starting from scratch with each update.

o        The user may choose between the 1998, 2002 or 2005 standards for their sign design.

o        The software operates in US standard or SI units. The user can convert back and forth by toggling a switch on the toolbar.

o        The software computes wind loads by analytical method rather than the simplified method.

o        The software provides the user with options for determining wind loads for signs.

·         Location and Topography

o        The software "reads" the wind speed maps (including the Continental US and Alaska) for the user with the same or better accuracy the user could achieve by "eyeballing" the map.

o        The software allows the user to describe the topography by using parameters for the topographic conditions included in ASCE7 Section 6.

·         Structure Design

o        The software allows the user to "build" the sign structure by defining multiple sign panels located at specified heights above grade. The software does not constrain the user to a set of preordained sign configurations.

o        The software provides a drawing of the sign structure as the user adds components.

o        The software permits the user to design one or two supports for a sign.

o        The software permits the user to design a basic drilled/cylinder shaped foundation for signs with pole supports.  The user inputs a foundation diameter and estimated soil condition and the program produces the depth required.  This is for volume estimations only, the program does not design the steel reinforcement. 

o        The software allows the user to obtain wind loads for the main wind force resisting system (MWRFS) at pre-selected height intervals or user-defined intervals.

o        When a sign structure’s geometry is completely defined, the program will additionally perform the computations for the wind loads at user defined stages of the sign support structure.

o        The software allows the user to select structural pipe and/or tube members for structural support components from a list of members based on the design criteria input.  

·         Calculations and Output

o        The user can "click" on various intermediate values of the MWFRS results to obtain the details of the calculations for a specific value, including: velocity pressure, gust effect factor, cf and net pressures. The software prints a full report of load for the MWFRS.

o         The program calculates a depth of a drilled/cylinder foundation for the calculated overturning moment and base shear created by the wind load on the sign design.   

o        The software provides calculators to allow the user to "play" with parameters without changing his current design. The user can print results from the calculators individually. The printouts include the data entered, intermediate calculations with equations, and the final answers.

o        The software will output the final structure to the Windows Clipboard™ to facilitate project estimating and communication with a registered professional engineer prior to final adoption of the structural design.



When the user completes computations of the Wind Loads on a Sign Structure, the program prints a report including the user defined data and the computed data suitable for developing project pricing and for presentation to a registered professional engineer for review.  (Note:  This program is designed to assist sign companies in determining the cost of adequate structural materials for a specified job prior to incurring the expense of a registered professional engineer.  The program is not designed to replace the services of registered professional engineers as required by established codes and ordinances.  In many cases, a registered professional engineer, experienced in sign design can provide an engineered solution with costs that will be less than the costs of material generated from this program.  In some cases where subjective parameters fail to meet the actual site conditions, the engineered solution may exceed the material costs projected by this program.)
