Abstract:
This paper describes a series of experimental research efforts focused on characterizing the ultimate flexural behavior of lightly reinforced concrete intake towers. The main objective of this research was to provide empirical data to be used in the development of a simplified analysis procedure for seismic evaluation of this type of structures. The studies included an experimental investigation of the flexural behavior of 1/8-scale model rectangular concrete intake towers under monotonic and cyclic lateral loads. Further experimentation was conducted to quantify the influence of the parameters governing the deflection capacity of these structures. An empirical expression is presented for the ultimate deflection capacity of lightly reinforced towers with rectangular sections.
