Abstract

During this half century excessive floor vibration due to normal occupant-induced loads has become a common concern in composite steel-concrete beam systems. This problem was addressed by a number of researchers until current codes and guidelines were introduced, although serious study did not begin until 1966. In the majority of studies some significant notes were made but some such as active modes have been over looked. In this study some of them will be researched and classified to solve problems in limited areas of the study. Thus, to numerically recognise the active modes in a composite system, 24 coupled composite steel-concrete beams are simulated and analysed by considering different length girders at differing distances. Nevertheless, it should be stressed that active elements will determine the main mode and direction of vibration in a system
