丁行义同志对“钢筋混凝土梁长期与反复荷载作用下的裂缝计算”的几点异议,经过详细阅读,提出了下列几点看法。供研究参考。 一、丁文认为张氏提出的长期裂缝公式仅用邕江桥一座桥的资料验证,感到有偶然性,可能导致过大偏差。南宁邕江大桥包括两个45米单悬臂及两个55米双悬臂,中间加3组22米 Comrade Ding Xingyi pointed out some objections to the “calculation of cracks under the action of long-term and repeated loads of reinforced concrete beams”. After reading in detail, the following opinions were put forward. For research reference. First, Ding Wen believes that Zhang’s proposed long-term crack formula is only validated by the data of a bridge on Qijiang Bridge. It is contingent and may lead to excessive deviation. Nanning Qiongjiang Bridge, including two 45-meter single cantilever and two 55-meter double cantilever, plus three groups of 22 meters
