【Abstract】 This paper briefly introduces the characteristic and analytical methods on the problems of geometric non-linear related to long-span bridge. Based on these, the geometric non-linear static and dynamic analysis of long-span bridge is discussed. Some related analytical methods are also presented. Finally the authors give their preliminary personal opinions on the problems needed to be solved.更多还原
