Abstract: Computerized online engineering tool system for specifying the various components of a holdown system that assemble a run comprising a tie rod in a frame wall structure from the foundation up through the walls to the top floor, and bearing members and tension devices securing the tie rod to the wall. The system comprises a server; a database of drawing elements and hardware component parts; a program operably associated with the server and the database with the steps of i) allowing a user to login into the server; ii) allowing the user to select options for the run; iii) providing the user a data input and calculated data page for the load at each framing level and rod size sufficient to handle the load; and allowing the user to download a shop or installation drawing of the run generated using the drawing elements and hardware component parts from the database.
