Additional information on hinges can be found in the CSI Analysis Reference Manual (Frame Hinge Properties, page 131). The P-M2-M3 hinge is best suited for nonlinear static pushover, whereas the fiber hinge is best for hysteretic dynamics. Unloading from the point of plastic deformation follows the slope of initial stiffness.īoth P-M2-M3 hinges and fiber hinges are available to capture coupled axial and biaxial-bending behavior. For informational purposes, additional limit states (IO, LS, CP) may be specified which are reported in analysis, but do not affect results.

The modeling of strength loss is discouraged, to mitigate load redistribution (which may lead to progressive collapse) and to ensure numerical convergence.ĬSI Software automatically limits negative slope to 10% of elastic stiffness, though overwrite options are available. Post-yield behavior is described by the general backbone relationship shown to the right. Hinges may be assigned (uncoupled) to any of the six DOF. Plasticity may be associated with force-displacement behaviors (axial and shear) or moment-rotation (torsion and bending). Multiple hinges may also coincide at the same location. To capture plasticity distributed along member length, a series of hinges may be modeled. Inelastic behavior is obtained through integration of the plastic strain and plastic curvature which occurs within a user-defined hinge length, typically on the order of member depth (FEMA-356). Elastic behavior occurs over member length, then deformation beyond the elastic limit occurs entirely within hinges, which are modeled in discrete locations. INTRODUCTION Nonlinear Static Analysis (PUSH-OVER): The nonlinear static analysis uses the simple inelastic approach which differs from a traditional static linear procedure that reduces seismic forces to levels that allow designing buildings under the assumption. We recommend that you complete five openSAP courses and topics from the Help documentation to gain the knowledge you need to pass the certification exam. Les explications très claires et bien illustrées. Pushover is a static-nonlinear analysis method where a structure is subjected to gravity loading and a monotonic displacement-controlled lateral load. You’ll learn how the exam works and the topic areas that will be tested. Suite à la demande de beaucoup d’adhérents nous vous offrons aujourdhui une excellente formation SAP2000 en PDF, c’est une formation concrète : théorie et pratique. Non-Linear Static Analysis Pushover Analysis in SAP2000. For nonlinear static, and nonlinear direct-integration time-history analyses, users may simulate post-yield behavior by assigning concentrated plastic hinges to frame and tendon objects.
