&lt;p&gt;I&amp;#39;m an internship in a Offshore Oil and Gas service and supply company and I started working with SACS recently. I have a question concerning fatigue analysis:&lt;/p&gt;
&lt;p&gt;What&amp;nbsp;are the steps to follows to do a&amp;nbsp;time history&amp;nbsp;fatigue analysis knowing that i have a force time history file of&amp;nbsp; 3 hours ( just for wind ) , and i chose a JS spectrum for the wave response input.&lt;/p&gt;
&lt;p&gt;These are the steps i followed but i had&amp;nbsp;abnormal results:&lt;/p&gt;
&lt;p&gt;1- Static Analysis (create a pile head superelement)&lt;br /&gt;2- Dynamic analysis (extract mode shapes)&lt;br /&gt;3- Dynamic analysis (Time history wave wind ,force)&lt;br /&gt;4- Post processing (Time history fatigue)&lt;/p&gt;
&lt;p&gt;regards, &lt;/p&gt;
&lt;p&gt;Marwane&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
