ABSTRACT
Abstract: Movement and distress in low rise residential buildings most commonly occur as a result of interactions between the footing system and the ground. This paper summaries the study that is carried out to evaluate the possible causes of distress in the G+2 Residential building founded on shallow foundation at Velacherry, Chennai, TamilNadu by detailed investigation. Disturbed and Undisturbed samples are collected by drilling borehole using auger. Laboratory test are carried out on disturbed and undisturbed soil samples obtained from the site of distressed building. The causes of failure of the structures are identified by considering the soil properties, intensity of loading, nature of foundation and pattern of cracks developed. Based on the degree of distress, the suitable measures are also recommended.
