SHORT- AND LONG-TIME DEFLECTIONS OF REINFORCED CONCRETE FLAT SLABS.
Abstract
This report summarizes the results of a field investigation to determine the short- and long-time deflections and concrete strains in an Army barracks flat-plate structure at Fort Hood, Killeen, Texas. Due to the rather great slab thickness of 9 in., corresponding to an L/T ratio of approximately 28, all observed deflections were small and in no instance exceeded 0.022 ft, or about 1/800 of the shorter span, during the 45-month observation period, in spite of an early temporary construction load estimated to have been almost 30 percent in excess of the total design load. The measured short-time deflections under various loading conditions compared reasonably well with deflections predicted by use of the ersatz frame analysis method. (Author)
