摘要
H型钢腹板强度与稳定性之间的矛盾是长期困扰工程界的一个难题,文中所研究的全波纹腹板H型钢在一定程度上缓解了这个矛盾。文中根据能量原理分析计算了承受均布下的全波纹腹板H型钢梁的腹板屈曲强度,给出了波纹腹板弹性失稳的临界公式,用实例说明了全波纹腹板H型钢的优越性,为这种H型钢在工程中的应用提供了理论依据。
Contradiction between thin wall and stability of H-beam is a kind of problem in engineering field, the corrugated web H-beam researched in this paper reduce the contradiction some extent. In this paper, the buckling strength of the web of whole corrugated web H-beam under the uniform compression loading is analyzed by the energy principle.And the critical load formulae of the corrugated web plastic buckling is given, supply theory to this kind of H-beam in engineering application.
