METHOD FOR SUPPORTING DESIGN OF ASEISMATIC REINFORCEMENT FOR BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a method for supporting the design of an aseismatic reinforcement for a bridge that can analyze a structure including a reinforcing structure by a finite element method (FEM) so as to ensure a strength design under an assumed load of actual horizontal seismic force in a structural design for the execution of aseismatic reinforcement works on a complicated structure such as a steel bridge. SOLUTION: An I girder 20 is drawn in a front view by two-dimensional CAD and is in every sectional shape converted to two-dimensional CAD data having a drawing and coordinate values on an arbitrary axis. The two-dimensional CAD data are converted to three-dimensional coordinate data, and according to the three-dimensional data, an FEM analysis model is constructed. Meshing, thickness and material characteristic information are given for an FEM analysis. COPYRIGHT: (C)2006,JPO&NCIPI
