hello！ 1.I use beamcolumnjoint element in RC Frame analysis. The period of the structure is so big. Somebody else also have this problem. 2. How to model Mat1 ~ Mat4 of the 4 springs in Joint2D element ? element Joint2D tag? Nd1? Nd2? Nd3? Nd4? NdC? [Mat1? Mat2? Mat3? Mat4?] MatC? LrgDspTag? tag: un...

I have the same problem. T is very big or infinite.
Try Joint2D element in altoontash dissertation.

I used BeamColumnJoint in RCframe
Gravity analysis and pushover analysis is OK

hi vesna
Could you give me your email ？

who can tell me what's the problem??
the eigenvalue analysis must have some problems

hi, everyone, I assembly BeamColumnJoint Element to the 3-story frame. But in this case you see no errors but I get a period above 6 seconds. The period of central Line model is just 0.5 seconds. # 1601 1701 1801 1901 2001 # -->04 ||========== ==||============||============||============|| # || || |...
