The previous data of 115 high-strength light-weight concrete and 330 normal concrete specimens are discussed statistically to investigate the ductility of light-weight concrete members. From the results, observed failure modes and critical ductility factor are generally confirmed using the calculated values of shear and bond capacities. The critical ductility factor observed for light-weight concrete members is about 90 % and 40 % of the normal concrete members in case of shear failure and concrete compression failure, respectively. The critical ductility factor of light-weight concrete members could be calculated using the values of capacities and other variables in spite of different failure modes.
