【Abstract】 Energy method of member structure is simplified so that the first natural frequency of structure can be calculated according to the static and dynamic line of deflection. In some conditions, the way is rapidly convergent and high degree of accuracy can be obtained. The effectiveness of the way is better. It can be used in engineering for reference.更多还原
