Hi Everyone
I am using R-CRISIS for seismic hazard map creation. I know how to use the given attenuation model in R-CRISIS but I want to use an attenuation model from a published article. How to make such an input file? Also, I would like to know, how to find out suitable spectral ordinate parameters for each zone for R-CRISIS? (It will be so helpful if you explain the later one in detail)
Hope Somebody can help me with this.
Dear Vivek G Babu
About your first question :
You have to create a text file according to the desired attenuation model and change the format of this text file from txt to ATN. Then, you should import the defined text file through R-CRISIS ( attenuation data>add user model) and then you have to assign this attenuation model to the desired seismic source. It should be noted that this method is for CRISIS2007 which is also applicable for R-CRISIS.
The mentioned text file should be look like the attached file. I think that Kramer's book explains how to make this text file. I have attached a manual which is in Persian.
About your second question:
The hazard curves often obtain based on Peak Ground Acceleration (PGA) and also most attenuation models are based on this spectral parameter.
