【摘要】 本文根据正常使用投限状态的要求,经过分析对比,明确指出应该按一台最大吊车的荷载来计算吊车梁的挠度并建议相应的限值。另外,对轮压增大系数α进行了理论分析,对现行资料中常用的α值做了补充和修正。更多还原

【Abstract】 This paper distinctly presents, by way of contrast and analysis, the suggestion of calculating thecrane girder deflection with only one largest crane loading according to the requirement of serviceabilitylimit states, as a result, the corresponding allowable deflection are given. Besides, the authors introducethe theoretical analysis, through which the wheel load enlargement coefficient α in conventional designmaterial is to be revised and supplemented.更多还原
