description | The assumptions of frame supports being hinged or fully rigid; storey masses being concentrated at the floor levels; distributed masses and deformations of the columns being neglected are frequently seen in dynamic analysis of frames because of less effort in calculation. In practice, however, column bases of frames may usually rotate and translate a little due to elastic behavior of soil. In this case, semi-rigid support behavior can be modeled using elastic spring against rotation at the column bases of frames. In this study, free vibration of semirigid supported single degree of freedom (SDOF) systems is studied including distributed mass and P-? effect of the columns and natural frequencies are obtained. Effects on frequency values of rotational spring coefficients at the column base and of axial force are presented in tables and graphs. |
