PBEE Toolbox Users's Manual

PBEE Toolbox is a set of Matlab functions, which are used to create a structural model according to Eurocode provisions, to perform the nonlinear seismic analysis by employing program OpenSees, and for post-processing of analysis results. In the manual the functions of the PBEE Toolbox are presented and explained. Following functions are available at this stage:

  • CBeamEnvelopeTakedaSlip,   CColumnEnvelopeTakedaSlip, CBeamEnvelopeHystereticSlip, CColumnEnvelopeHystereticSlip. These functions determine the moment-rotation relationship of reinforced concrete beams and columns.
  • OS_tcl_Model_Takeda_Slip, OS_tcl_Model_Hysteretic_Slip. These functions create the model for OpenSees. Results are tcl files, which are input files for OpenSees.
  • Eigen,  EigenAnalysis, Pushover, PushoverAnalysis, Dynamic, DynamicAnalysis, DynamicSeries, DynamicSeriesAnalysis, SingleIDA1Analysis, SDOFDynamicAnalysis, SDOFIDAanalysis, ImposedDisplacement, ImposedDisplacementAnalysis. These functions create tcl files for OpenSees and runs selected type of analysis in OpenSees from Matlab environment.
  • PushoverDamage, SingleIDA1Damage. THese functions determine the damage at the level of plastic hinges.

PBEE Toolbox Examples of Application

The objective of this report is to show the capability of the PBEE Toolbox. In the first example the pushover analysis, nonlinear dynamic analysis and IDA analysis is presented for the four-storey reinforced concrete frame building, which has been designed according to previous versions of Eurocode 2 and 8. The results of the nonlinear dynamic analyses are compared with the results of the pseudo-dynamic tests, which were performed in the ELSA Laboratory in Ispra. The results of the pushover analysis are used to determine the target displacement for a defined seismic loading. The target displacement is determined according to the N2 method and according to the SDOF-IDA approach. Further on the influence of some selected modeling uncertainties on the seismic response is presented. The second example is four-storey frame, designed to reproduce the design practice in European countries about forty to fifty years ago. In this case only the pushover analysis and the nonlinear dynamic analysis are performed. The results of the nonlinear dynamic analysis are presented with the results of the pseudo-dynamic test.
