Analysis on design of replacement concrete reinforcement for frame columns in a unfinished continuation project
A unfinished continuation project has serious quality defects such as concrete segregation and insufficient concrete strength grade in the peripheral frame columns.To ensure the safety of the building structure,reinforcement design is needed.This article designs a re-placement concrete reinforcement scheme based on the mechanical properties and degree of damage of the components through analysis and calculation.The plan provides a detailed analysis to the design of the surrounding beam,the supporting steel between the surrounding beams,the beam end steel support,the replacement sequence,and the monitoring plan.According to the observation results of settlement de-formation of the replacement column,the replacement effect of this scheme is reliable and safe.
