Nonlinear static analysis of cable-stayed bridge structures

Time Domain Buffeting Analysis of Suspension Bridges Subjected to Turbulent Wind With Effective Attack Angle

“…In spite of the fact that the behavior of the material of the structural elements in a long-span bridge is linear elastic, the overall load}displacement relationship for the structure is non-linear [13]. This overall non-linear behavior originates from (i) the in#uence of cable sag to its equivalent modulus of elasticity, (ii) the e!ect of initial stresses on structural sti!ness and (iii) the e!ect of large displacements on structural sti!ness and loads.…”

Analysis of cable-stayed bridges during construction by cantilever methods

“…The element force corresponding to u j is denoted by S j , in which S 1 and S 2 are the end moments and S 3 is the axial force. When the beam-column effect has to be taken into consideration, the beam-column element stiffness matrix has the following form [4,5]: …”

“…The sources of nonlinearity in cablestayed bridges mainly include the cable sag, beam-column and large deflection effects. A lot of studies on this kind of bridges have been done in the last half century [4][5][6]9,10]. But few papers presented concerns with the analysis of cable-stayed bridges during erection stages in construction.…”

Finite Element Analysis of Cable-Stayed Bridges with Appropriate Initial Shapes Under Seismic Excitations Focusing on Deck-Stay Interaction

“…where b E , b A , b I and b L are the modulus of elasticity, the cross-sectional area, the moment of inertia and the length of the beam-column element, respectively; s C , t C and t R are the stability functions representing the interaction between the axial and bending stiffnesses of the beam-column element [26]. In general, large displacements occur in the deck-tower system due to the large span and less weight of a cable-stayed bridge.…”
