The invention discloses a truss structure optimization method based on non-probability reliability. The truss structure optimization method based on the non-probability reliability comprises the following steps: according to the stress and intensity of a truss model, checking and limiting a rod member as the solid circular rod; according to the non-probability reliability index, determining the rod member of the statically determinate truss with the reliability; and setting the sectional area of the rod member so as to satisfy the non-probability reliability index. The truss structure optimization method based on the non-probability reliability has the following beneficial effect: the steel amount for the truss is respectively reduced to 32.9% and 33.4% under the initial condition. Under the requirement for satisfying the structure system reliability, the quality of the truss structure is greatly reduced.
