{live-template:Tutorial} {info} This tutorial was initially written for [SAP2000|sap2000:home], though the general procedure also applies to [CSiBridge|csibridge:home]. {info} \\ {on-this-page} \\ An overview of the procedure for *pushover analysis* is given as follows: h1. Create the computational model * Create the computational model, without pushover data, using conventional [modeling|kb:Modeling techniques] techniques. * Define properties for pushover [hinges|kb:Hinge] using Define > Section Properties > Hinge Properties. Hinges may be defined manually or by using one of several default specifications which are available. * Assign the pushover hinges to selected [frame|kb:Frame] objects using Assign > Frame > Hinges. * Select Define > Load Patterns to define [load patterns|kb:Load pattern] which will contain the loads applied during pushover analysis. h1. Define a nonlinear static load case * Select Define > Load Cases > Add New Load Case to define a [nonlinear|kb:Nonlinear] static [load case|kb:load case] which will apply the previously-defined load pattern. This load case may be force-controlled (pushed to a specified force level) or displacement-controlled (pushed to a specified displacement). * Select Other Parameters > Results Saved to Multiple States such that various parameters may be plotted for each increment of applied loading. h1. Run the analysis * Select Analyze > Run Analysis to run the static-pushover analysis. h1. Review results * To plot base shear vs. monitored displacement, select Display > Show Static Pushover Curve. Additional variables are also available for plotting. * To plot hinge deformation vs. applied loading, select Display > Show Hinge Results. Moment as a function of plastic rotation is one such option. * To review displacement and the step-by-step sequence of hinge formation, select Display > Show Deformed Shape. * To review member forces on a step-by-step basis, select Display > Show Forces/Stresses > Frames/Cables. * Select Display > Show Plot Functions to plot response at each step of the pushover analysis, including joint displacement, frame member forces, etc. h1.
