%X It is may be limited by the test technology conditions or by the test fee that tests the inherent frequency for a super big structure using common experimental method.Therefore,according to the similarity theory,the present paper introduces a simulation method,which can use a small model to gain the inherent frequency for a super big structure by means of the frequency similarity rule K_f educed from the differential equilibrium equations of dynamics.The method is not only simplicity,but also economy.It is more fit for a generally engineering research,which is limited by the condition and the fee.So,we obtain a research way in experimental simulation of inherent values for super big structures.As a engineering example,we discuss the inherent frequency values of a super big concrete platform from a steel factory with the method in this article.The results is identical sufficiently when it is compared with the finite element method.
