In this study 2 models are subjected to different load cases involving gravitational loads, temperature loads, seismic and wind loads in the presence and absence of expansion joint and the parameters like displacements, drifts, bending moments and steel consumption were evaluated. From the study it was observed that both the Models showed considerably lesser values of parameters like Steel consumption, Maximum Bending Moments, Storey drift and Average displacements in the presence of an expansion joint. Based on the overall output is can be suggested that the elimination of the expansion joint should be considered only for Model A because in case of Model B the structure was seen to become very uneconomical with increased values of the parameters compared under higher seismic zones.

INTRODUCTION An expansion joint may be defined as a mid- structure separation designed to relieve stress on a building material which are experienced during the life span of the structure. The expansion of the structure depends upon numerous factors like architectural aspects of the structure, temperature changes, provision for temperature control, materials of construction etc. Expansion joints are necessary in a structure as they counter the adverse effects a structure experiences during its lifespan due to temperature variations [1-3]. This study can be helpful in Civil Engineering as it gives a clear picture of the changes a structure undergoes when subjected to temperature loading and also its variation under different seismic zones. II. LITERATURE REVIEW Michael J Pfeiffer and David Darwin (1987) in their report gave a brief description of the process involved in working out an expansion joint in buildings, the purpose of each type of joint and its selection based on requirement [4]. René de Borst and Paul P.J.M. Peeters (1989) developed an algorithm by simultaneously considering the effect of thermal dilatation, changes in elastic properties with increasing temperatures, and the calculations were carried out with the DIANA finite element code [5]. James M Fisher (2005) studied and examined different structures with his focus basically on the provision of expansion joint and the basic guidelines used to determine the requirement of an expansion joint at any given location and also on the requirements of the expansion joints pertaining to commercial and industrial structures [6]. It also includes some of the basic formulae to be used for determining the general information regarding expansion joints in structures. Matthew D Brady (2011) had discussed the guidelines for dealing with dimensional changes in building structures under the effect of changing temperatures [7]. It also includes the additional details regarding the need, location, type, codal requirements and recommendations of expansion joints. B. Dinesh Kumar and K. Vidhya (2014) presented a study involving the analysis of a G+1 RCC structure without an expansion joint and difference in floor heights for its behavior under different loadings [8]. The comparisons of column rebar and support reactions were done and were observed to be almost similar in both the cases. Previous studies done on similar topics involve work done on expansion joints or temperature loading alone and also how the behavior changes under different seismic zones. A combined effect of these two parameters is hardly available and also does not portray a clear image of the complications faced in terms of changes in the RESEARCH ARTICLE OPEN ACCESS
