High-Strength Concrete Joints Under Cyclic Loading

This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American Society of Civil Engineers) Committee 352 on Joints and Connections in Monolithic Concrete Structures (1985). The recommendations, concerning the design of joints that are part of the primary system for resisting seismic lateral loads, are based on tests of normal-strength concrete connections with compressive strength f' c ranging between 3500 and 5500 psi (24 and 38 MPa).
