Abstract
Special programs and general programs applied to suspension bridge analysis have their limitations. This paper focuses on ANSYS-secondary-development and makes it possible to analyze suspension bridges both with accuracy of special programs and convenience of general programs. This paper is dedicated to saddle simulation,incremental launching realization and how to obtain unstressed length of main cable and slings and how to keep it unchanged. In the end, the method is verified through finite element model in Runyang Yangtze River Bridge.
Keywords
