| Abstract: | The concerned problems on using symmetry for displacement method to solving statically indetirminate structure are discussed in this paper. Attention is paid to and serious exposition is made on these problems: the meaning and application of symmetry ;the determination of supporting conditions and types of simplified structure in the light of given deformation conditions;the result on using symmetry in simplifi cation; and the accurate application of slope-deflection dauation equation,etc. Through practical examples,the result on using symmetry for displacement method in solving statically indeterminate strusture is clearly illustrated. And the correctness of calculation result of the exampe is checked with the monent distribution method. |
