【 摘 要 】

The issue of determining actual stiffness of beams and columns of concrete frames is discussed in the initial part of the paper. This is followed by description of some of the most frequently used flexural stiffness models. Then the influence of selected beam and column stiffness models on the distribution of bending moments in a real-life frame is analyzed. Conclusions for the selection of adequate frame- element stiffness models for analysis of relevant internal forces, aimed at achieving similar level of safety for beams and columns, are given in the final part of the paper.
