| Abstract: | A new plane triangular element with rotational degree of freedom at each corner is con- formed from ten-node isoparametric element in this paper. The character and precision of the new element are the same as those of isoparametric element , the rotational definition of the new element are the same as those of isoparametric element , as the rotational definition of the new element is the same as that of continuum mechanics. |

| Keywords: | rotational degree of freedom triangular element isoparametric element frame- wall structure |
