摘　　要：通过试验研究了天兴洲长江大桥箱型压杆加劲板的极限承载力,并与加劲板的极限承载力的理论计算结果进行了分析对比。试验结果表明天兴洲大桥箱型压杆带加劲肋板件设计是安全合理的,试验与计算结果能够较好地吻合,说明应用于箱型压杆中加劲板的极限承载力理论分析研究方法是可行的。This paper conducts a test study of the ultimate carrying capacity of stiffening plates for the compressive box members of Tianxingzhou Changjiang River Bridge and analytically compares the study with the theoretic calculations of the ultimate carrying capacity of the plates.The results of the study indicate that the design of the compressive box members with stiffening rib plates of the Bridge is both safe and rational;the tests accord with the calculations fairly well and the theoretic analysis and study ...
