Title: Safety management of reinforced concrete bridges in China and evaluation methods for strength of existing RC bridges with crack
Abstract: In recent years, safety problem of bridges becomes a public topic and threatens people's living property; it also has become great hidden danger. This paper analyzes the main problems existing in the safety management, provides some improving measures, and points out the importance of safety operation on construction sites and its later maintenance and management. Based on the studies about damage bridges assessment on the level of materials and components, the author made a comparative analysis on the damage mechanism and applicable conditions, and put forward the amended formulas for calculating the flexural and shears capacity. The assessment formula for shear capacity was established as well, and in which various impact factors of shear strength was considered comprehensively.
