... discussed above, it is evident that despite comprehensive research programmes being carried out on the tubular joints with various strengthening methods, none have focused on CFS tubular T-joints reinforced with side plates at chord–brace junction under combined compression and bending. Therefore...

...Kexin Zhang; Tianyu Qi; Dachao Li; Xingwei Xue; Zhimin Zhu Purpose The paper aims to investigate effectiveness of the strengthening method, the construction process monitoring, fielding-load tests before and after strengthening, and health monitoring after reinforcement were carried out...

.... The displacements and concrete strains of the bridge at mid-span were measured during the test. Design/methodology/approach This paper describes an innovative technique, external prestressing, used to strengthen a 36-year-old prestressed T-beam bridge. This paper introduces the construction process...

...Hongshuai Gao; Quansheng Sun Purpose With the rapid development of transportation and the continuous increase of traffic volume and load level, some bridges cannot meet the use requirements, and the demand for bridge strengthening is growing. Furthermore, bridges are affected by factors...

...Jiawei Wang; Yanmin Jia; Guanhua Zhang; Jigang Han; Jinliang Liu Purpose Most existing studies are confined to model beam tests, which cannot reflect the actual strengthening effects provided by prestressed carbon-fiber-reinforced polymer (CFRP) plates to existing bridges. Hence, the actual...
