Hello, I’m doing a pushover analysis for a Nonlinear concrete frame. The NonlinearBeamColumn elements with 5 integration points are selected. After the gravity analysis, a pushover analysis with load controlled pattern is conducted. I tried many solvers but all of the strategies cannot complete the ...

1. Don't forget to create the folder firstly;

2. use the command ''wipe' after the whole analysis;

3. Many other typos in your script may also create zero-output.

Hello, I'm trying to generate the total accel. of a node with the pattern of UniformExcitation. The command I put is recorder Node -file $Path/Accel_Node1.out -node 1 -dof 2 accel; That is, the OpenSEES record the relative accel. of node 1 in the 2nd DOF. However, how can we get the total accel. of ...

During my IDA of a relatively complex 5-stories and 3-spans concrete frame, the OpenSEES program failed to converge and the program crushed. The error messages are listed as follow: WARNING BandGenLinLapackSolver;;solve<> -factorization failed, matrix singular U<i,i> = 0,i=62 WARNING AcceleratedNewt...
