For calculating stress of BNS body structure, a thin-walled eccentricbeam element witch accords with demands is introduced in this paper. The eccentricity existing in truthful structure.
针对客车车身结构的受力计算，本文提出了一种更符合实际结构的薄壁偏心梁单元。

The results show that the beam can be an eccentric tension member, meanwhile the performance of shear wall must be considered.
转换梁应作为偏心受拉构件，同时要考虑剪力墙参与工作部分。

The eccentric cam beam pumping unit make full use of original member and optimize key member, so it makes each member's force rational, and energy sav…
