ANALYTICAL MODELING SYSTEM OF RETRACTABLE LARGE SPACE STRUCTURE USING PARAMETRIC METHOD

摘要

The present invention relates to an analytical modeling system of a retractable large space structure using a parametric method, which facilitates geometric reproduction of an atypical roof including a retractable roof through parametric modeling, automatically inputs a load to a structure in consideration of a driving mechanism of a roof, and efficiently performs structural analysis and review of results of alternatives repeatedly performed in a design process. For the structural analysis of the retractable roof structure, in which a movable roof runs along a main runway truss, in a computer program, the analytical modeling system of a retractable large space structure using a parametric method comprises: a parametric load distribution module for distributing a load of a movable roof member to a node corresponding to a main runway truss member, wherein the main runway truss and the movable roof are modeled by the main runway truss member and the movable roof member, the movable roof member is parameterized to vary the position of the movable roof member according to the input opening/closing rate of the movable roof; and a structural analysis module for having the main runway truss member matched with member information, and receiving load information calculated by the parametric load distribution module so as to match the load information with a joint of the main runway truss member to perform structural analysis.;COPYRIGHT KIPO 2019
