Abstract
Resent research has focused on the potential loss in structural performance of reinforced concrete members with ASR related damage. In this research, deterioration and remained pulling shear stress evaluation method for ASR damaged concrete foundation of steel tower is developed by aiding finite element method. Expansion strain occurred on site due to ASR was identified by sensitive analysis of ASR model with comparing measurements of cracking pattern, crack width distribution and crack density of crown and body of concrete foundation. This method can evaluate stress state of concrete, rebar in structure and decreasing tendency of pulling shear stress corresponded to concrete expansion by ASR.
