一、问题的提出在港口工程结构中(如钢闸门),常采用型钢作为受弯构件。型钢梁受弯时,牢固焊连在型钢上的钢板(面板),可以考虑作为计算截面的一部分;它与型钢形成整体共同变形与受力。所计入的钢板宽度B,应按有关规范的规定取用。当考虑钢板参加型钢的抗弯工作时,型钢的截面显然应比只由型钢单独抗弯时要小些, First, the issue put forward In the port structure (such as steel gate), often used steel as bending member. Bending steel beam, the firm welded steel plate (panel), can be considered as part of the calculated cross-section; it with the steel forming a common deformation and stress. The included steel width B, should be taken in accordance with the relevant provisions of the specification. When considering the steel plate to participate in the bending work, the section of the steel should obviously be smaller than when the steel alone bending only,
