thanks alot

hi every body i have little problem when i use recorders in bellow: recorder Element -file $data3/prCols1st.out -time -ele 1 2 plasticRotation the OpenSees print bellow: 0.01 4.45E-07 4.70E-06 -7.44E-07 4.45E-07 7.44E-07 -4.70E-06 0.01 i dont know whats that numbers? are they rotaion of end and star...

Hi every body I have an problem with dynamic analysis!! I want to know, if I want to use analysis Transient for dynamic analysis, I should only use ground motion or accelerate on my structure? Because I have an 3D space structure, I define mass, damping, load and analysis as following. But the opens...

thanks vesna, very very thanks

Hi every body I have problem, that there wasn’t any where (OpenSees Command Language Manual & example). I have some load that have Trapezium shape time series. Its mean that the load have linear value (for example increase from 0N to 10 N) from time 0 to 2 second ( with Linear Time Series) , and...

hi every bodi
does any body have cods about progressive collapse?
its aboute remove a member and analuse the structure
any body can help me?

hi every body i have an problem i analyzed an 3D space structure in SAP and OpenSees. all of the properties are equal in both but the answers of analyse are different, the axialforce of member in OpenSees are lower than SAP. and when i wrote the below code the both answer are equal: # FINITE ELEMENT...

ok! when i increase gravity loads on the structure, from 100 N to 10000N, the internal member force increase from 30 N to 56 N, and this procedure has continued. means that when i increase the load on the structure at 10000000000000000000 N , the members are still safe and support internal forces bu...
