2. Response of Building to Wind Event

The following are the requirements for response of single structure due to wind action. The requirements are being met by the WE-UQ application. These requirements are broken down into a number of groups, general, wind loading, building description, analysis, and UQ. All requirements in this section are related to work in WBS 1.3.7.
