    • PROBLEM TO BE SOLVED: To solve such a problem that since a panel has out-of-plane deformation when a panel zone is hollow whereby a bending moment applied to a beam can not be borne by a web in an elastic area, a section modulus of beam ends is the section modules of only a flange excluding the web, and thus the strength of beam ends is lowered, so that a larger beam than in the case of bearing the bending moment by the whole section of the beam has to be used and an extra beam depth is required, which results in an increase in the weight of a steel frame.
      SOLUTION: The thickness of a diaphragm is increased, and a backing board is arranged on an upper or lower face of the beam flange, the material strength of the beam flange is increased, the thickness of the diaphragm or the backing board is increased, a cutout is formed in the web, or a prestrain is applied by heat wiring a lower face of the beam.

    • 解决的问题为了解决这样一个问题,即当面板区域是中空的时,由于面板变形,由此施加到梁的弯矩不能由弹性区域中的腹板承受, 梁端部的截面模数是除了腹板之外的只有凸缘的截面模数,因此梁端部的强度降低,使得比在梁的整个部分承受弯矩的情况下更大的梁具有 并且需要额外的光束深度,这导致钢框架的重量的增加。

      解决方案:隔膜的厚度增加,并且背板被布置在梁凸缘的上表面或下表面上,梁凸缘的材料强度增加,隔膜或背板的厚度为 在卷筒纸中形成切口,或者通过将梁的下表面进行热布线来施加预应变。 版权所有(C)2011,JPO&INPIT
