摘　　要：三角形曲面壳元在单元交界处的切线是连续的，能更真实地反映结构的几何形状，本文利用广义协调三角形板单元ＴＧＣ－ ９的法向位移场与三角形线性膜元位移场相结合，通过假设膜应变的方法构造了一个广义协调三角形扁壳元，数值算例表明该单元具有精度高且收敛快的优点。As the tangent on the boundary of elements is continuous, triangular shallow shell elements are more suitable for the analysis of shell structures. Combining the displacement field of the generalized conforming plate element TGC-9 and the triangular linear membrane element, a generalized conforming triangular shallow shell element is formulated by the assumed membrane stranin method. Numerical analysis of examples show that the element has the characters of higher precision and quick convergence.
