Abstract
Unlike cast in situ construction, precast concrete construction is a type of construction in which the concrete elements used in the structure are not casted on the site but are made off site usually in a factory or casting yard and are cured and treated and then transported to the construction site where they are assembled via connections. In many precast concrete structures especially in European countries, the main components of the structure comprise precast concrete walls (both interior and exterior walls) as these walls play dual role of resisting lateral as well as gravity loads. As these walls are joined together on the site itself; their stability against lateral loads is an important concern. In this paper, stability against overturning, sliding and stress checks of precast concrete walls of a structure with number of stories varying between 3 and 4 is done using European codes. The structure has simple rectangular plan. The analysis is done using Microsoft excel sheet and Mathcad software, and the effect on the precast walls due to torsion in the structure is studied. Also, various provisions are taken to make the unstable walls stable, and at last the need for the precast construction in India is accessed.
