TESTING STUDY ON STRESS AND FRICTION RESISTANCE OF PRESTRESSED T-SHAPED GIRDER
【摘要】 对预应力“T”型梁钢束的预应力、孔道摩阻以及在静荷载试验条件下的应力进行了试验研究,结果表明“T”型梁钢束应力满足规范要求,孔道摩阻受施工质量的影响。
【Abstract】 Testing study is made on the prestress, friction resistance, and the stress distribution of the T-shaped girder under static loading. The testing results show that the T-shaped girder is available to meet the national specification and the friction resistance of hole is related to the construction quality.
