Resposne of Reinforced Concrete Plate-Column Connections to Dynamic and Static Horizontal Loads, Volume 1

The object of the investigation was to study the response of interior reinforced concrete plate-column connections. Eight specimens were tested, 5 "statically" and 3 "dynamically" (rate of loading significant). Other experimental variables were reinforcement ratio and the amount of superimposed vertical load. The specimens had certain common characteristics. Nominal slab dimensions were 1.8 by 1.8 m.; slab thickness was 76mm. The column was square with dimensions of 0.3 by 0.3m. The reinforcement layout in the slab was isotropic. The statically tested specimens provided information on the influence of the change in reinforcement ratio and the amount of superimposed vertical load on the response to horizontal loading. 'An analysis model (the "grid model II) was developed to help interpret the results from the statically tested specimens. The dynamically tested specimens were used to obtain data on the response of the specimens, the observed hysteresis and calculated damping.National Science Foundation Research Grant PFR 78-1631
