Hi Frank and all, I was wondering is there any way to apply fix pore pressure value in brickUP element during time history analysis. I want to do gravity analysis and after gravity analysis, I want to fix the pore pressure at the base of the model at constant value, during my time history analysis. ...

What type of property you are using?
Can you post your model and material property?

I had the same problem when using PDMY material. One solution to prevent the problem to happen is to update the materialstage to 0 ( during linear elastic). Also update the material shear modulus and bulk modulus to the value you originally defined in you material. So, you are providing the same dat...

Hello everybody, Finally, I solved my problem. I got 2 Gegabytes data from the 3D analysis of building, just for one analysis. Initially I was trying to insert the outdata into MYSQL server using insert command of mysql from VB.net. I found that this proceessing taking too much time. It took me 3 hr...

Thank you Silvia.
I am late for replying your post. Just today, I tried according to your suggestion and I got exactly I wanted.

Thank you again.

Dear All, I would like to know, is it possible to compile opensees in Unix, AIX OS. I cannot find any definition file on the source code that I have download from the opensees website. Please, provide me detail information about compiling Opensees in AIX. If possible please post the definition file ...

Dear All, HAPPY NEW YEAR 2009! Today, I would like to ask help about the handling of output of OpenSees. In my work, I am recording all the information of nodes and my model contains huge number of nodes. When I got the output file, the file size is around 300 MB. It is really a huge text file to do...

Dear Silvia, I would like to know how to record the responses only for specified interval of time. For example, if I am running dynamic time history analysis and my ground acceleration data are at time period is 0.05 sec. But I only want to recode the response of the structure at 0.5 sec time step o...

Thanks a lot!!! Silvia: If I use SP command. I got one problem. SP command work for first cycle when I applied the displacement in x direction but when I changed the displacement to y direction (Next cycle). It applied the displacement in y but at the same to it applied also in x direction even thou...

Dear Silvia, I want to test a column under bi-axial loading using displacement control. I need to apply different displacement history in x and y direction( x and y are the axes for applying displacement control to the column). In my loading history, first loading will be applied to x direction at t...

Thank you for help. Actually I wanted to ask about how to apply the static triangular load on the element like beam. I need to analyze building so that I am distributing the self wt. of slab as trapazoidal loading on the tributary beams. However, in OpenSees I cannot find any command which provide m...

Hello Everybody,
Could you please suggest me how to apply the nonuniform distributed force (Triangular loading) in the member.

Thank you

Thank you for your help.
Actually, I want to know how to select this "Lambda" parameter. What is the reason that you select 0.1 in your analysis? why not 0.15 or 0.2 or....???

I hope I will get answer of my query.

Thank You
