The detailed procedures for high-speed cyclic loading test and the authors’ first-hand experience during the tests of reinforced concrete beam-column connections subjected to cyclic displacements at frequencies as high as 20 Hz is documented in this paper. It is found necessary to give special attention to the quality of the instruments to successfully perform high-speed data acquisition. Problems faced in different phases of the high-speed tests that are not common in pseudo-dynamic tests are highlighted. The applicability of some basic criteria established for quasi-static and seismic performance in gauging the high-speed dynamic performance is also discussed. Unlike in pseudo-dynamic tests, the inertia force contributed significantly to the readings of load cells integrated with the actuators that apply the high-speed displacement cycles. The shear capacity of the tested joints was higher than that computed with the empirical equation in seismic design codes.
