Boards and Transverse Stiffeners Effects on Floor Vibrations of Light-Gauge Steel Structure and Time History Response Calculation

Office buildings of Light-gauge Steel Structures have long floor spans in recent years. Design methods for suppression of vibrations induced by walkers are necessary for the lightweight floors. One approach is to use two-way action of joist floors that have been published by research reports for timber structures. Effects of boards on the steel joist, anti-vibration bars and lateral stiffeners are shown by acceleration measurements under ball and walking excitation. Also time history calculation of the single-degree-of-freedom system as easy design methods is introduced in this paper.
