Seismic Analysis and Rehabilitation of Corroded Reinforced Concrete Building
Corrosion of reinforcing steel is a primary cause of degradation of reinforced concrete (RC) structures. The process of carbonation and chloride attack are the factors responsible for corrosion which lead to loss in the structural performance of buildings during their service life. The time dependent corrosion process effects the safety and serviceability and may even lead to progressive failure of structures. Corrosion leads to reduction of reinforcing bars diameter, cracks in concrete, concrete cover expulsion, decrease in concrete and steel strength and loss of bond between concrete and embedded steel. In multistorey concrete buildings, corrosion is a much more serious concern with regard to their seismic performance. Hence, steps of the accurate assessment and establishment of the existing corrosion level of the structural elements and evaluation of the local and global seismic capacity of existing corroded RC buildings have been a great challenge globally. In the present study, a methodology has been adopted where based upon the non-destructive and destructive material’s site as well as laboratory tests, revised properties have been adopted for seismic evaluation and establishing the proper rehabilitation scheme for the existing two-storey RC framed buildings. Obtained results for sound, corroded and retrofitted building from linear seismic analysis and nonlinear static pushover analysis have been compared and discussed.
