Analytical studies of a cable stayed girder bridge

摘要: Abstract The paper deals with the linear and nonlinear behavior of a cable stayed girder bridge subjected to static dynamic conditions load. Particular reference is given designed by Division Bay Toll Crossings for Southern Crossing San Francisco Bay, California. loads displacements considered are symmetrical vertical plane which includes central longitudinal axis roadway girder. orientations cables diamond-shaped towers in three dimensional space taken into account. A theory presented determining effects on bridge. employed influence lines various parameters bridge, maximum caused specified live loads, temperature changes, differential movements. based direct application Muller-Breslau's principle structures composed finite elastic elements. also obtaining selected cases load distributions. Special attention distributions forces moments girder, cables. general For load, determining, (1) camber dimensions each unstressed segment (2) displacements, forces, at section stages erection, (3) possible overloads vehicular traffic segments required fabrication determine camber. insure that all dead prescribed designers, obtained after erection. other studies needed modes failure during use theory, nonlinearforce-deformation relations tangent stiffnesses kinds members encountered analytical model. axial-flexual lie space, catenaries. axial-flexural members, influences eccentricities
