I dont really understand what ground motions i should use, and how to implement these in the. Pushover is a staticnonlinear analysis method where a structure is subjected to gravity loading and a monotonic displacementcontrolled lateral load pattern which continuously increases through elastic and inelastic behavior until an ultimate condition is reached. Additional variables are also available for plotting. In this it is necessary to define the plastic hinges. A 12span existing rc bridge was selected for the case study.

Pushover analysis sap2000 itme analizi nonlinear pushoverperformance point. The hinges hinges are points on a structure where one expects cracking and yielding to occur in relatively higher intensity so that they show high flexural or shear displacement, as it approaches its ultimate strength under cyclic loading. It helps in understanding the deformation and cracking of a structure in case of earthquake and gives you a kind of fair unders.
