function time history analysis (data)

[Anonymous]

I have two storey steel building in France ( Saint-Nazaire)
load
dead load :
   roof : q= 45kg/m2
   floor :q= 235kg/m2
imposed loading
              q=350kg/m2
wind :  zone III-IIIb
snow : 1A
seismic action:
zone 3
Soil type : A
I can design
1.lateral force method of analysis
2.modal response spectrum analysis
But I don’t understand design time history analysis.
How can I import time history functions? Here; this is Saint-Nazaire (France)
Data time history where I can research  ?
 If would not be of too much trouble for you guys, can you make a video or a tutorial, 
sorry for my English
thanks

bonjour à tous
j’ai un batiment deux niveaux. Je peux modéliser par
1.methods d’analyse par forces latérales
2.analyse modale utilisant les pectres de réponse
mais je n’ai pas compris analyse temporelle. Comment je peux définir la fonction du temps.
ici c’est saint Nazaire. Quel site je peux rechercher diagrammes déplacement-temps.
Ci joints un fichier de robot. Est-ce que vous pouvez faire une vidéo pour guide utilisation

Check this thread:

of course look at posts related to seismic, tha, not related to modelling

hi rafal.
how can i create THA function corresponding to my spectrum/ earthquake. This is my problem ? 
this is my spectrum

[Rafal.Gaweda]

I do not know.

Unfortunately it is not a simple operation.

The method of creating response spectrum compatible artificial ( synthetic ) accelerograms is described for instance in the "Response Spectrum Compatible Accelerograms" chapter of  the "Dynamics of Structures" by Ray Clough, Joseph Penzien.

Some topics related to proper selection of accelerograms are discussed in this paper:

Hi  pawel
thanks for answer
I’ve read scientific articles
As a common basis for this study we queried the PEER Ground-Motion Database

(http://peer.berkeley.edu/peer_ground_motion_database/spectras/new) to find the ten accelerograms

with 5.8≤Mw≤6.2, 0≤rrup≤20km and 400≤Vs30≤600m/s

that best match the French version of the Eurocode 8 (EC8) design spectrum for a EC8 class B site

in scientific they chose corresponding to class B site

I can to find any accelerograms or corresponding to my class  ?

how can I to find the accelerograms corresponding to my class ( A, B , C,D…) ?

Let me know if this help you, Great Massimo Speziani!!!

Too bad.. the program is in Italian 😞
