Abstract:
Conside ring o r neg lec ting the a xial defo rmation o f compone nts , the buckling lo ads of steel po rtal f rame are studied
by the precise tr ansfer matrix method(PTMM).Accor ding to the principle and slig htly bending equilibrium differential
equa tion of com pr essio n bar , the PTMM fo r stability ana ly sis of steel por tal frame is built under axial fo rce .and the buckling
loads of steel por ta l frame unde r hing e suppo rt are so lv ed .The re sults we re basically identical with the result by finite
e lement me tho d.This show s that the me tho d is right and effective .Ba sed o n the alg orithm mentio ned abo ve , the stability
analysis of steel por tal frame with dfiffere nt boundary co nditionis has been do ne .Some ex amples indicate that the buckling
loads of steel po rtal frame conside red ar e identical with tha t w hich is neg lected .The sug g estion is giving no co nsider ation
to the axial deformation of compo nents to analy sis the stability of steel po rtal f rame .
