The relationship between axial stiffness, torsional stiffness, flexural stiffness and deformation has been given.

Based on the bifurcation buckling of abnormal beamcolumn steel frame,it was found that the way to ascertain column s effective length of normal steel frame can also be used in abnormal beam-column steel frame;the principle of virtual work was used to deduce the flexural stiffness of two kinds of Abnormal beams,and its effect on the effective length of rigid steel frame column was analyzed.

One of the key problems of this technique,such as flexural rigidity of the RC beams strengthened with CFL,must be discussed.

Static test of eight steel-light weight concrete composite beams with re-entrant trough profiled steel sheeting specimens were conducted to study the flexural rigidity of the composite beams.

Based on the flexural rigidity of curve box girder,This paper proposes the concept of equivalent span,and transforms the space analysis of continuous curve box girder into the foree analysis of plaae structure.
