Abstract: Computerized methods and systems for modeling a structural frame of a building. One or more client computers and a central server are coupled to a data communications network. The central server receives a plurality of input parameters representative of design characteristics of the building frame from users via the client computers. The central server consolidates the input parameters according to a defined hierarchy among the users to resolve conflicts between two or more of the input parameters. The central server further generates a building frame model based on the consolidated input parameters to optimize construction of an actual building frame according to the model. The model assigns load values to load bearing members of the building frame based on connections between the members.
