Static and Dynamic performance of RCC framed structure subjected to Geometric and Material non linearity

Abstract

 Extensive research in the field of construction materials has led to the manufacture of improved materials and the engineers are familiar with the properties of the materials more than ever before. This has helped to predict the behavior of the structure in its entire intended time of service. Finite element based software can now predict the structural elements that may becritical in due course of time. These analyses are tedious to perform manually but can be dealt with quite easily using finite element based analysis software such as one used in the present study i.e. ETABS.In the present work the effects of second degree analysis such as sequential construction analysis along with Geometric and Material non linearity are studied. Geometric and material non linearity are both second order analyses which help to determine the future loads and conditions on a structure. And help the structural engineers design the building so that it remains serviceable for its entire intended life. In this paper the conventional analysis is compared against time dependent Geometric and Material non linearity.
