IBP Integral Back-Pressure

Consequently, the shell wall is subjected to local axial compression from the beam and the circumferentially uniformly distributed overall axial compression resulting from the self-weight of the upper part and the roof.

壳壁因此承受由梁传递来的局部轴向压力,同时承受由上部壳体、顶盖等自重形成的沿环向均匀分布的整体轴向压力。
