Hi
I've modeled an unanchored tank (shell elements) resting on ground (solid elements). I have given a seismic record to the ground and I want to get the base shear and overturning moment of the tank as my history outputs during the analysis. My question is which categories should I tick when...
Hi
I'm trying to model a 3d liquid tank with acoustic elements and steel shell. I've also used springA elements and a solid mass to serve as a damper. The whole system is subject to an earthquake record. I would like to know which one of these suits this type of analysis better? Transient...
Hi
Is the modal analysis of unanchored tanks (simply placed on the ground) with abaqus any reliable given the nonlinear nature of the problem? I've obtained some results for convective and impulsive modes but don't know if they are any valid or not.
Hi
I'm trying to model an unanchored storage tank using FE software Abaqus. I wanna run a modal analysis and find out the frequencies for main impulsive and convective modes. However, I need some analytical equations for these two in order to verify my results. Is there any design code or...
Hello
I want to model an unanchored tank subject to real-life earthquake loading. The problem involves contact and separation between the tank and the rigid ground and also fluid-structure interaction. Should I use dynamic explicit or dynamic implicit step for this purpose? How time consuming...
Dear all,
I'm trying to model a liquid storage tank using abaqus. The tank is anchored at the bottom and I've modeled the liquid (water) with acoustic elements. I am trying to verify my model by comparing it to results of previous research and experimental studies so I need to extract certain...
Hello All
I'm relatively new to ABAQUS and I am trying to model a liquid tank using coupled Eulerian-Lagrangian (CEL) technique for seismic analysis. My problem is that I cannot extract the natural frequencies and modes of the liquid-filled tank because abaqus/standard doesn't support Eulerian...
