• SACS Dynamic - Extract Mode Shape

    Hi! Tried to run the dynamic extract mode shape for a seismic analysis. However, received error message as follows from output listing file. Not able to trouble shoot. Hope to receive favorable advise from all of you. Thank You.
  • How to import Craig-bampton super element in a dynamic SACS analyses ?

    I created a Craig-Bampton dynamic super element as per methodology described in "SACS Dynamic Superelement" document. I created a wave response file so as to have be able to create a reduced force vector. Spectral check is directly done in the listing…
  • Dyn mode shape analysis for MAT support jacket

    Hello Can I know how to use SACS to do dynamic analysis for those mat-supported jackets? E.g., How to mode the soil-foundation interaction to solve the super element, similar to what we have done for those piled jackets? Otherwise, we have to ignore…
  • How to perform SACS dynamic analysis (Dynpac) with COG shift for topside

    Hi, I'm currently design a susbtructure and the topside come with couple forces for COG shift. When I conduct the dynamic analysis (Dynpac) for the model, I suspect that SACS actually converts the couple forces into mass, the natural period increase…
  • Dummy Pile in SACS

    Can I run a simple 2D dynamic model with dummy pile in SACS?
  • RE: Dypac with superelement

    Thanks Geoff for your answer. Having Said that, you are suggesting to ignore DEAD Load case when generating mass matrix. Where can it be modified ? in Dynpac File or in Dynamic Super element file ? I am doing a preliminary analysis of pile Stick Up…
  • Dynamic Super Element Analysis

    Dear SACS users, I have been trying to perform dynamic super element analysis to set up a load iteration process with the turbine manufacturer. I tried to follow the steps menioned in the help file of DSE analysis as much as possible. I made a simple…
