The Capacity Assessment about Existing Reinforced Concrete Bridge with Cracks
Recently, bridge deterioration with time and ever increasing traffic loads raise concerns about safety and durability of aging bridges. Based on the studies about damage 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，This paper combined with results of previous studies, based on the structural damage assessment research, reinforced concrete beam structure correction formula is given in the event of cracks and shear cracks.The assessment formula for shear capacity was established as well，and in which various impact factors of shear strength was considered comprehensively.
