![]() The following fields are optional and will show up on you printed page.Įxception from part 3 page 320 (Use the calculator below) Example 55'-8" is written as 55.67Įnter an optional Tributary area between 10 and 500 square feet at (MRH 60 ft). See below for additional information about the Kd factor.įor determining Zone 5 dimension "a". See below for additional information about Kzt. Refer to section 26.8 and figure 26.8-1 to determine the wind speed-up effect. Thank you in advance.ĭesign Load Method: ASCE7-10 Strength Design Load & Allowable Stress Design You may get an email about updates to the wind load program or changes to this website. If you enter your email address, you can be rest assured it is safe and will not be sold. The program will let you know when the conversion has happened after the design pressures are calculated.īe sure to enter all required fields. This will cover the mean roof height and least building width. Finally, I added programing to accommodate the use of feet and inches to be converted to decimal feet as the program requires. See the calculator below to verify the exception can be used. I added a check box to force the program to utilize part 1 when using the exception rule in part 3 which allows the use of part 1 for heights greater then 60 feet and less than 90 feet. Since the introduction of the ASCE 7-16 code, I made a few revisions to the ASCE 7-10 program. In these calculations the ASD velocity pressure is reduced by 60%. In general the LRFD will be used for the main structure and the ASD will be used on the components and cladding. For me the biggest change utilizes the LRFD (Load Resistance Factor Design) and ASD (Allowable Stress Design). Refer to your local jurisdictions to determine which map and wind speed to use. The Wind speed maps are separated into category 1 through 4. A few of the key changes are: The Importance factor used on the older code is no longer used and is built into the wind speed maps. There are many references on the web about the big changes to the ASCE7-10 code. The program will automatically determine Part 1 or Part 3. This program utilizes Part 1: Low-Rise Buildings h60 ft to calculate the design pressures. Refer to the bottom of this page for various building code web site links.Īs you will see in the Asce 7-10 Building Code there are four parts for determining the components and cladding. It is highly recommended you review the building code to understand where the information comes from. I use these programs to verify the design pressures provided by the architects or to create them for estimating or engineering purposes. The program displays the Wall Components and Cladding design pressures for the selected conditions. (Can you see the pattern? Three versions on every major number X, X.1, X.2)ĬadTools use late binding to AutoCAD's COM object, that's why you need to type in the Reference String.Here is a web enabled Asce7-10 wind load program. Generally you need to change the three last digits so it match your AutoCAD version, the list below may be useful along with some "try and error". What shall i type in? The string (reference to COM object) used by CadTools depends on AutoCAD versions. It would be nice if you could continue to use CadTools on coming AutoCAD versions. "Manually (type in self)" option for CAD version Parameter in the settings? This is a sample from the "HelpFile": The first option in the list is "Manually (type in self)", this option is useful if by any reasons development of CadTools is halted and there are newer versions of AutCAD on the market. Zwcad has a identical COM object model to AutoCAD (the first I've seen so far) and it was easy to fix CadTools. BricsCAD, ProgeCAD and others built on Intellicad won't work. Nice to know that CadTools is appreciated.ĬadTools can be used with any CAD software with identical COM object model as AutoCAD.
