TY - JOUR ID - 756 TI - Nonlinear analysis of semi-rigid frames with rigid end sections JO - Iranian Journal of Science and Technology Transactions of Civil Engineering JA - IJSTC LA - en SN - 2228-6160 Y1 - 2007 PY - 2007 VL - 31 IS - 5 SP - 567 EP - 571 KW - Semi-rigid KW - nonlinear KW - plane frame KW - rigid-end section KW - Critical load DO - 10.22099/ijstc.2007.756 N2 - This work presents a computer-based analysis of semi-rigid steel frames. The geometric nonlinearity of the structure and the material nonlinearity of the connections are considered in the analysis. The critical load has been searched as a suitable load parameter for the loss of stability of the system. Several examples are presented to demonstrate the validity of the analysis procedure.            UR - https://ijstc.shirazu.ac.ir/article_756.html L1 - https://ijstc.shirazu.ac.ir/article_756_b278561984690eb78e0dee48165f6604.pdf ER -
