| 利用折析壳有限元方法了薄壁截面杆件受横向荷载作用时膜应力的大小和分布规律。认为对薄壁杆伯上端部力的近似等效原则为合力，合力矩都给定，则离杆端远处的应力就其本确定。 |

| Problems of Approximate Equivalent of End Force on Thin-walled Beams |

| Abstract: |
| The size and distribution of stress in thin-walled bearns loaded by lateral force are computed through fold plate and shell FEM. The approXimate equivalent principles of ended force on thin-walled beams can be stated as follows: if the resultant force,resultant moment,bimoment and cross bimoment are given,then the stress on the far end of the thin-walled beam can be determined. |
| Key words: equivalent force,thin-walled beams,cross bimoment |
