hi and thanks cbrn: yes,i set Global Y-axis as spectrum direction,but my structure is symmetric, its cross section is circular then i think that there is no diffrent in x or y direction,but in spectrum analysis when i set global y -axis as specrum direction i check y displacement.do u think...

hi please some one help me to solve this problem. it is urgent to me. thanks

hi dears: I have a structure and do two seismic analyses with it. 1-spectrum analysis 2-transient analysis But the thing that is very strange is different result obtained from them. Stress, nodal displacement, and ......are different. I expect that at least nodal displacement at top of...

hi SKJoe thanks alot for your response, i do every things that u said but again like my past problem when i check the result at nodes that I set the displacment load, there is difference between my load data and the data that shown in post26 result plot. I don't know why it happened,please help...

hi thanks for your response as you know people usually use solid65 element for concrete then because of it i didn't say any thing but befor TBDATA command i wrote: TB,CONCR,1 TBDATA,1,0.25,0.25,0.1E6,7E6 IS it correct? i mean that do i describe tensile strenght like this? strenght of my concrete...

hi my dear freinds i want to see crack in solid65 element and describe a tbdata like this : TBDATA,1,0.25,0.25,0.1E6,7E6 IS it correct? i mean that do i describe tensile strenght like this? strenght of my concrete material is 0.1Mpa. thanks regard

please help me if someone knows it. thanks in advance regard

I intend to do a transient analysis and using dis versus time data as displacement load at the base of my Structure,I make a table using *Dim and set it as displacement load in my problem(D command),but I don't know how to set up my transient analysis option, do I have to describe separately a...

Hi every body I had 1560 acceleration versus time data(ELCENTRO EARTHQUAKE DATA) and I wanted to do a transient analysis, after I saw more topics about seismic and transient analysis I understand that I have to convert my acceleration data to displacement so I use *VOPER and INT2 commands to do...
