5-Creating target spectrum according to TSC2018

To obtain the spectra given in TBDY2018, we use the SeismicInputs class for seismic inputs. For seismic recording input, an instance of our SeismicInputs sample class is purchased. This class will also be used in other classes.

SeismicVariables = SeismicInputs(lat = 39.85,lon = 30.2,soil = "ZC",intensity = "DD2")
SeismicVariables

Latitude :39.85

Longitude :30.2

Soil Class :ZC

Intensity:DD2

We provide information about the building model in the SeismicResistanceBuildingInputs class. Here we used DuctilityLevel, ResSystemType, SlabSystem which are Enum classes for classifications.

RCBuilding = SeismicResistanceBuildingInputs(Hn=70,
                                                 I=1,
                                                 DuctilLevel=DuctilityLevel.Yuksek,
                                                 ResSystemType_X=ResSystemType.BAKarma,
                                                 ResSystemType_Y=ResSystemType.BAKarma,
                                                 SlabSystem=SlabSystem.Plak_kirisli)

SeismicInputsManager class is used to find spectrum values. This class uses the information of the SeismicVariables class as input and calculates the other values if the SetVariables function is run and sets them to the class properties.

SIM = SeismicInputsManager(SeismicVariables=SeismicVariables, TL=6.0)
SIM.SetVariables()
SIM

Ss :0.737 S1 :0.195 PGA :0.309 PGV :18.833 Fs :1.205 F1 :1.5 SDs :0.888085 SD1 :0.2925 TA :0.06587207305607008 TB :0.3293603652803504 TL :6.0

SeismicResistanceBuildingManeger class takes SeismicResistanceBuildingInputs, which contains building information, and SeismicInputsManager classes, which calculate seismic data, as input, and calculates general building classification operations by running the SetVariables function and sets properties.

Srbm = SeismicResistanceBuildingManeger(BuildingVariables=RCBuilding, SeismicManager=SIM, BuildingClass=SeismicResistanceBuildingsClass.A14, Rx=6,Ry=3)
Srbm.SetVariables()
Srbm

SeismicResistanceBuildingManeger(BuildingVariables=Hn :70 I :1 DuctilLevel :Yuksek ResSystemType_X :BAKarma ResSystemType_Y :BAKarma SlabSystem :Plak_kirisli, SeismicManager=Ss :0.737 S1 :0.195 PGA :0.309 PGV :18.833 Fs :1.205 F1 :1.5 SDs :0.888085 SD1 :0.2925 TA :0.06587207305607008 TB :0.3293603652803504 TL :6.0, BuildingClass=<SeismicResistanceBuildingsClass.A14: 5>, Total_M_DEV=0, Total_M_o=0, DTS=2, BYS=2, Rx=6, Ry=3, Dx=1.0, Dy=1.0)

The Spectrum class calculates the spectrum information of the structure by running the SetVariables function using the SeismicResistanceBuildingManeger class and sets it to the ElasticSpectrums variable. This property returns pandas.DataFrame.

Spec = Spectrum(BuildingManager=Srbm)
Spec.SetVariables()

Spectrum(BuildingManager=SeismicResistanceBuildingManeger(BuildingVariables=Hn :70 I :1 DuctilLevel :Yuksek ResSystemType_X :BAKarma ResSystemType_Y :BAKarma SlabSystem :Plak_kirisli, SeismicManager=Ss :0.737 S1 :0.195 PGA :0.309 PGV :18.833 Fs :1.205 F1 :1.5 SDs :0.888085 SD1 :0.2925 TA :0.06587207305607008 TB :0.3293603652803504 TL :6.0, BuildingClass=<SeismicResistanceBuildingsClass.A14: 5>, Total_M_DEV=0, Total_M_o=0, DTS=2, BYS=2, Rx=6, Ry=3, Dx=1.0, Dy=1.0))

The plot_Spectrums function can be run to display all plots simultaneously. Graphs are drawn in one piece in a specially prepared format.

Functions in related classes can be used individually. For example, elastic and reduced elastic spectrum values for a certain period can be obtained with the help of the following functions.

Sae_Tp = Spec.Get_Sae_Tp(T=1.2,
                         TA = Spec.BuildingManager.SeismicManager.TA,
                         TB = Spec.BuildingManager.SeismicManager.TB,
                         SDs= Spec.BuildingManager.SeismicManager.SDs,
                         SD1= Spec.BuildingManager.SeismicManager.SD1,
                         TL = Spec.BuildingManager.SeismicManager.TL 
                         )

Sar_Tp = Spec.Get_SaR_Tp(R  = Spec.BuildingManager.Rx,
                         D  = Spec.BuildingManager.Dx,
                         T  = 1.2,
                         TB = Spec.BuildingManager.SeismicManager.TB,
                         I  = Spec.BuildingManager.BuildingVariables.I,
                         TA = Spec.BuildingManager.SeismicManager.TA,
                         SDs= Spec.BuildingManager.SeismicManager.SDs,
                         SD1= Spec.BuildingManager.SeismicManager.SD1,
                         TL = Spec.BuildingManager.SeismicManager.TL  )
