FINITE ELEMENT METHODS FOR SOLVING STRUCTURE COMPOSED BY PLATE-BEAM WITH THEIR ERROR ESTIMATE
板-梁组合构件的有限元解法及其误差估计

In this paper, we study the convergence of finite element solution of structurecomposed by plate-beam. To begin with, we give a conforming condition for this compositestructure. According to this condition, in general the finite element methods for solving thecomposite structure are shown, in general, to be non-conforming. Based on Strang'sframework, the convergence of the finite element solutions is proved one by one and theirerror estimate is given.
