Abstract

Abstract

With the extensive application of pre-twisted beam in engineer structure,it is very important to carry out analytical research of pre-twisted beam,put forward a dependable mechanics analysis model and the calculation theories.The analysis of mechanical property is carried out based on small deformation assumption to get the displacement general solution,and verify its accuracy using ANSYS software.The paper indicates that the general displacement method is feasible,and the displacement of pre-twisted cantilever beam is larger than non-twisted one,and because of pre-twisted angle,the lateral displacements appear.At the same time,the presented general solution offers an accurate displacement interpolation model.
