problem in Incremental Dynamic Analysis

Post by alirezatabriz »

Hi, I have a serious problem in my IDA curves. I used steel02 material and forceBeamColumn elements with fiber section in modeling but in my models Dynamic Instability occurs when the maximum story drift is equal to 1 ( equal to my story height )!. Does anyone know where is the problem ?
