摘 要: 针对刚性介质接触条件下钢板局部屈曲的特点,利用能量法,推导刚性介质接触条件下钢板的局部屈曲强度的计算公式,并与无刚性介质接触条件下钢板的局部屈曲强度比较,研究发现刚性介质的存在使钢板的局部屈曲强度显著提高。为了方便工程应用,对理论推导的公式进行简化,提出了刚性介质接触条件下钢板的局部屈曲系数的简化计算公式。 In accordance with the characteristic of local buckling of steel plate in contact with rigid medium,the calculating formula of local buckling strength of steel plate in contact with rigid medium using energy method is deduced,compared with local buckling strength of steel plate without contacting rigid medium.Then,the local buckling strength of steel plate is enhanced remarkable by using rigid medium is pointed out.The calculating formula is simplified to be able to use it in engineering,and the simplified calculating formula of local buckling factor of steel plate in contact with rigid medium is developed.
