 <fs medium>With the fabric formwork modeling techniques defined, the four step procedure outlined above may now be used to design a fabric formed concrete panel.  A first step in obtaining an optimum panel design requires that the load paths to the boundary supports be determined – a result of the lateral loads.  The anchors are then placed at these locations anchoring the panel to the backup framing system.  If, for architectural reasons, the panel is to be configured with predetermined load paths and anchor locations, this step could be omitted.</fs> <fs medium>With the fabric formwork modeling techniques defined, the four step procedure outlined above may now be used to design a fabric formed concrete panel.  A first step in obtaining an optimum panel design requires that the load paths to the boundary supports be determined – a result of the lateral loads.  The anchors are then placed at these locations anchoring the panel to the backup framing system.  If, for architectural reasons, the panel is to be configured with predetermined load paths and anchor locations, this step could be omitted.</fs>
