Beam188是三维线性（2节点）或者二次梁单元。每个节点有六个或者七个自由度，自由度的个数取决于KEYOPT(1)的值。当KEYOPT(1)＝0（缺省）时，每个节点有六个自由度；节点坐标系的x、y、z方向的平动和绕x、y、z轴的转动。当KEYOPT(1)=1时，每个节点有七个自由度，这时引入了第七个自由度（横截面的翘曲）...

The deflection and rotation functions of the element boundary are obtained from the Timoshenko's laminated composite beam functions, hence convergence to the thin plate solution can be achieved theoretically and shear-locking problem is avoided naturally. The plane displacement interpolation functions of ...
beam elementsteel-concrete composite structuresSteel-concrete members are an example of layered systems with interlayer slip. To analyze such systems theoretically, layered beam elements, derived from the standard two-noded ones, may be employed. Special LB-ele...
During the past few years, a number of different finite elements for Timoshenko beams, which include shear deformation and rotary inertia effect, have been published. In this paper, a beam element which has three nodes and two degrees of freedom per node is used for the analysis of free ...
