ABSTRACT:

In this paper, the widely used pointwise equilibrating polynomial (PEP) element which is able to consider the local second-order effect (bowing effect) efficiently and accurately is improved based on Timoshenko beam theory. PEP element adopts a fifth order polynomial for the lateral displacement field and was derived under Euler–Bernoulli beam theory, so it neglects transverse shear deformation and can only apply to thin beams. To fill in this gap, this study revises PEP element based on Timoshenko beam theory allowing for transverse shear deformation and then the application scope of the element is extended.  The proposed element uses a fifth order polynomial for the lateral displacement field as PEP element and a linear shear strain filed additionally. The derivation of internal forces and tangent stiffness matrix of the element is detailed in this study. Besides, numerical examples are investigated to verify that the proposed element not only inherits the good properties of PEP element but considers transverse shear deformation accurately
