<t>Dear Earthquake Experts,<br/> <br/> I am currently dealing with Indian Standard on earthquake (IS1893). In this standard default response spectrum is given for 5% damping ratio and additionally multiplication factors are given to correct the response spectrum for other damping ratios. In my case ...

<t>Hello huffte, indeed it might look like an ambiguous question. Actually, I was asking it keeping in mind the answer of ruipinho in the same thread from yesterday. As I understood it yesterday for example EC8 specifies response spectrum for given site conditions. The acceleration at zero period is...

<t>Dear ruipinho and huffte, thanks so far for your very supportive feedbacks. In order that I have understood ruipinho's answer properly, I would like to take one practical example. For example, my location in Germany falls in Type 1 and ground type E category as per EC8 with PGA equivalent to 1.4g...

<t>Dear Seismosoft tool experts,<br/> <br/> I am perhaps confused with a very insignificant question. For several recorded accelograms the PGA is reported as 0.3g or 0.4g etc in case of major earthquakes. But in case of response spectrums mentioned in various country specific seismic codes the PGA i...

<t>Dear SeismoSoft team,<br/> <br/> I would request an improvement that user could specify the start point of the artificially generated accelogram. For example user may be interested that earthquake stars at 30s in his simulation and not directly at 0s to avoid combination with any instabilities in...

<t>Hello, in case of large wind turbines, the structural frequencies of as low as 0.1 to 10Hz are generally interesting with large slender components. For such a case what should be the range of chosen period of response spectrum in SeismoArtif to generate artificial accelogram? Also our load calcul...

Hello, are there any rules to specify the duration of artificial accelograms generated with method 2 or 3 in SeismoArtif? Thanks in advance!!

Hello huffte, Thank you very much for your fast and sufficiently detailed answer.

<t>Hello, I am interested to make artificial accelerograms using SeismoArtif (method 2 or 3) for use as input in dynamic analysis of large wind turbines combined with all other wind and operational loads. In SeismoArtif their is a big choice of Envelope Shapes but I am not completely sure which one ...
