The static characteristics of a suspension bridge with a span of 78 m are analyzed.The original geometrical shape of the main cable is measured under no-load condition.Then,the measured data are introduced into the finite element model for geometric nonlinear simulation.Finally,the load test is carried out to observe the change of the sag of the main cable control section under the action of the graded load.The measured data are compared with the theoretical values calculated by the finite element analysis software.The measured values of the measured points are less than the theoretical value ...
