| Description | Earlier, we understood that a single-storey building frame can be represented by an equivalent single degree of freedom spring mass system (Den Hartog, 1985). Similarly, a two-storey frame can be represented by a two degree of freedom (2DOF) system, a three-storey frame can be by a three degree of freedom system and so on and an n-storey frame can be represented by an N degree of freedom system provided that the assumptions made in the SDF system are made again here, i.e., the storey masses are lumped and the rotations of the columns are restrained at the floor and roof levels. We can include or not include the dampers in the spring mass system depending on choice. However, damping has to be included to be realistic. A damping of about η = 5% is generally assumed for concrete frames, a little lower value of η = 2% for steel. Again, in steel frames, the damping depends on whether the joints are bolted, riveted or welded. Book Name: Structural Dynamics in Earthquake and Blast Resistant Design |
