THE AUTHORS' ANSWER TO DISCUSSION BY DR.JUN KANDA (Jun KANDA, J. Struct. Constr. Eng., AIJ, No.504, 141-142, Feb. 1998)

Abstract

The point of the discussion made by Dr. Kanda on the classification of design load into two classes is whether the ultimate and serviceability limit states are considered separately during the design stage. In the current deterministic design method, two levels of design load are determined separately. Under the principle of this method, the serviceability limit state is exceeded with probability 1.0 when the ultimate limit state is exceeded, and the thresholds of these two limit states and the event of exceedence are considered separately. It is reasonable for the probability-based design method to be based on the same principle for the smooth transition from the deterministic design method.
