Abstract
AbstractTwo deck floors, with different lateral stiffnesses, were constructed to measure lateral loads generated by occupants that are needed for design of residential or commercial exterior deck-type floors. Load was measured with two load cells attached at each end of the ledger representing the attachment to the building. The decks were supported on rollers, simulating minimal lateral resistance from columns. Occupants performed two different types of dynamic actions, in two orthogonal directions, at occupancy live load levels of 0.48, 0.96, 1.44, and 1.92 kPa (10, 20, 30, and 40 psf). The first loading cyclic was a side-to-side swaying motion that could result from a deliberate synchronized movement such as dancing. The second was an impulse-type load, which simulated horseplay-type activities. The difference in stiffness between the two decks resulted in a significant change in the human–structure interaction. Significant inertial effects were observed when the flexible deck was loaded parallel to th...
