This paper deals with the sensitivity study on reliability or failure probability of uni-directional fiber reinforced composite lamiIlates Subjected to off axial loads. Two kinds of fi1ew Sensitivity measures, Physical and stochastic sensitivity ones, Were defied in the present first order reliability method (FORM) . The former means these filsitivity measure which shows how the mean value of randompara-meters affect the safety index of lamilates based on FORM. The latter is the variability sensitivity Which is the measure bow the standard deviations of random variables vary the failure probability of laminates. Both the ses1itivitie scan be easily calculated as1alytically with safety index and standardized gradient coeficients on a design point by the present procedure. The proposed sensitivity measures have an only an a dvantage to be obtainedanalytically butalsoto of fermoreil formation re-liability tha the conventional numerical procedure. Numerical analysis of graphite epoxy uni-directioIlal compositeslaminates was performed for the various combination of off-axial loads. These results are useful for a desigrlerto evaluate the quantitative characters of design parafieters which contribute the stochastic material design of composite materials.
