Wind Loads on Structures 2019 (WLS2019) performs all the wind load computations in ASCE 7-98, ASCE 7-ASCE 02, ASCE 7-05, ASCE 7-10 and ASCE 7-16 Standards. The software allows the user to "build" structures within the system, such as buildings, signs, chimneys, tanks, and other structures.

The below table describes features of the Wind Loads on Structures 2019 program. 

Features Pricing

New functionality

  1. Wind load computations in ASCE 7-16.
  2. Direct access to ATC Hazards by Location site. 
Features
Computes wind load calculations by analytical method rather than the simplified method.
Provides the user with options for determining wind loads for buildings, chimneys, tanks and similar structures, trussed towers, signs and domed structures.
Allows the user to describe the topography by using parameters for the topographic conditions included in ASCE 7-05 Section 6 or ASCE 7-10/16 Chapter 26.
Allows the user to construct a "building" structure by adding sections. The software does not constrain the user to a set of preordained footprints.
Provides a composite drawing of the structure as the user adds sections.
Program incorporates all roof types and combinations defined in ASCE 7-05 or ASCE 7-10/16, Chapters 27-28.
Allows the user to define roof slopes in terms of degrees or as a ratio (x:12) and to input all salient roof dimensions.
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.
When a building is completely defined in terms of geometry, the program will also perform the computations for the wind loads of user defined Components and Cladding.
For standards ASCE 7-05 (and later), open structure provisions have been added to allow monosloped, pitched and troughed roof shapes.
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, Cp, Cf and Net Pessures.
The software prints a full PDF report of wind loads for the MWFRS and Components & Cladding methodologies.

Note: 
After the release of WLS2019, SDG will no longer support versions of Wind Loads on Structures released prior to 2019. In addition, SDG will issue a license for WLS2019 for one year. If you wish to continue using WLS2019, you must renew annually. Failure to renew the license will result in WLS2019 not operating. SDG must do this to continue operating and providing technical support. For every year your serial number has expired, you will be charged an annual fee until that amount equals the cost of the new purchase.
