Hi
what are CR1,CR2 in steel02 material?
Thank you

Hi,

How can I get period at each time step in time history analysis?

Thank you.

Thank you,
can you send me your program? please.

yes, I get the same result without pdelta: sap:7.7136cm opensees:7.71354 cm equation:7.71354cm It's important that: pdelta plas large displacements in sap2000 = displacements with corotational in opensees but displacements with pdelta effect in sap2000 isn't equal with pdelta effect in opensees in m...

Hi, in my model cantilever 2D with these properties: lateral load V=1000kg gravity load P=-20000kg cross section A=23.9 cm^2 modulus of elasticity E=2.1e6 kg/cm^2 moment of inertia I=1317 cm^4 length L=400 cm under static analysis, lateral displacement with p-delta effect is: with opensees:12.5562 c...

Hi,
what is difference between p-delta and corotational coordinate transformation?
