5. Capabilities¶
Version 3.0.0 of WE-UQ app was released July 2023. The following lists the functionality available in this current version. (Note: New features and fixes in this release are marked blue in the following list of features.)
5.1. Structural Information Model¶
Applications used to specify/select the structural model to be used in the analysis.
MDOF: creating idealized multi-degree-of-freedom models
MDOF-LU: auto-generated multi-degree-of-freedom model
OpenSees: user-defined OpenSees models
CustomPy: user-defined OpenSees models
5.2. Wind Loading Event¶
Applications used to specify/select wind loading for the structure.
Stochastic Wind: simulating stochastic wind speed using spectral method
CFD-Digital Wind Tunnel: CFD simulation of boundary layer wind tunnel
CFD-Wind Load on Isolated Buildings: CFD-based wind load simulation for isolated buildings
DEDM_HRP: database-enabled design framework based on wind-tunnel data for high-rise buildings
LowRiseTPU: extracting aerodynamics loads based on TPU database for low-rise buildings
Wind Tunnel Experiment: uses pressure tap measurements from building in wind tunnel experiment
Existing: User-supplied time-varying floor loads
5.3. Engineering Demand Parameter Generator¶
Applications to identify the output parameters of interest given the wind loading and the structural model.
Standard Wind: (serviceability) inter-story drift ratio, peak floor acceleration
User Defined: user-specified EDP
