Does the software RWIND Simulation consider the wind directionality factor (Kd) from the ASCE 7-16?


The wind directionality factor (Kd) from the ASCE 7-16 Sect. 26.6 is not automatically considered in the ASCE 7-16 wind load profile or RWIND Simulation calculation. The wind directionality factor (Kd) can be considered in RWIND Simulation by modifying the load case factor for the load cases generated by RWIND Simulation in RFEM. These equivalent load case factors can be edited and customized under the "Load Combinations" tab with in the "Edit Load Case and Combinations" dialog box.

This factor for various structure types can be determined from table 26.6-1 from the ASCE 7-16 [1].
