RESEARCH ON THE INITIAL FAILURE LOAD OF COMPOSITE FIBER REINFORCED PLASTIC BOX GIRDER
摘要
Abstract
A theoretical calculation method for the initial failure load of CFRP box girder is established by combining the classical laminated plate theory and the folding plate theory.The initial failure load of the box girder of [04/±45/04],[02/±45/02/±45/02] and [±45/02/-±45/02/±45] is calculated by this method.At the same time,the three-point bending experiment is carried out on the CFRP box girder by using DNS100 electronic universal testing machine.The theoretical calculation value of the initial failure load of the composite box girder is compared with the experimental value.The theoretical calculation error is less than 4%.The results show that the theoretical calculation method of the initial failure load of the composite box girder is correct and the higher the 0° ply ratio,the initial failure load of composite box girder is higher.关键词
