Analysis Method of Elastic Foundation Frame for Medium and SmalI Hydropower Stations

Liao Jungang(Guangxi Institute of Water Resources & Electric Power)  
The features of the analysis method advanced in this paper for elasticfoundation frame are as follows:1.The elastic foundation is simulated by using somevertical elastic columns whose bottom are fixed on rigid foundation;these cloumnstogether with the frame form a new structure system,and the system is solved by usingfinite member element method.2.The effect of depth of the elastic foundation on thedeflection and the internal forces distribution of the frame can be reflected.3.The effectof the rigid parts for the nodes together with the deflection of members caused bybending,pulling or pressing and shearing can be considered in analysing the Structure.
