Student, Dept of Civil Engineering, M G M College of Engineering & Technology, Kerala, India Professor, Dept of Civil Engineering, M G M College of Engineering & Technology, Kerala, India -----------------------------------------------------------------------------***---------------------------------------------------------------------------Abstract – In today's scenario, steel frame structures play an main advantage of steel structure is that it exhibit postimportant role in the construction industry because they are elastic behaviour. efficient, sustainable, durable, flexible and safe. To analyze the structure subjected to seismic loads, the deformed geometry In general, ground movement due to an earthquake can and the non-linear behavior of the structure must be occur anywhere in the world and special attention must be considered. Therefore, to determine the performance of the paid to the danger related to buildings, especially under structure, non-linear or a pushover test is performed. The strong seismic forces. While reinforcement is provided in the thrust test was performed on two frames, namely bare frame structural system in the construction of the structure, the and steel reinforced frame. Steel braced structural frame is location of the bracing must be in an effective position to one of the structural systems used to resist earthquake loads in make the building more rigid. Most of the steel braces used multistoried buildings. Bracings are required to inhibit lateral are X, V, inverted V, etc. Introduction of pipe damper in buckling the members For the better performance of brace bracing will enchance the seismic performance. So this pipe frame in building x shaped pipe damper is installed in brace deals with the study of the inverted V-type bracing system beam connection to enchance the seismic performance. So this with X shaped Pipe Damper(XPD) in steel constructions. study deals with the study of the inverted V-type bracing Push over analysis is the preferred analysis procedure for system with X shaped Pipe Damper(XPD) in steel seismic performance evaluation purpose and it also gives constructions. Push over analysis is the preferred analysis post elastic behaviour. Analyse and evaluate seismic procedure for seismic performance evaluation. The objective of Performance of bare frame and brace frame with XPD is this paper is to evaluate the response of bare frame and done with help of ANSYS software . braced frame with XPD subjected to seismic loads and to identify the suitable size of XPD in brace frame for resisting the 1.1 XPD seismic load efficiently. From the study it is obtained that brace frame with XPD provide better seismic performance The proposed damper is made through welding two than brace frame in terms of ductility, yield displacement, oppositely positioned pipe halves to forma X-shaped core, ultimate displacement and ultimate load and connecting the X-shaped core to side plates with circumferential welds. The XPD (X-shaped Pipe Damper) Key Words: X Shaped Pipe Damper, Bracing, Lateral damper provides the lateral resistance and energy Buckling, Steel Structure dissipation behaviors initially through flexural bending of pipe plates, and latter through the tensile stretching at 1.INTRODUCTION composite pipe halves [1]. The production process of XPD is simple and the pipes are easy to obtain. So, XPDs as in Steel frames play important role in the construction industry cooperate with brace frames will provide more seismic because they are profitable, sustainable, durable, flexible and resistant structure. sure. Recently, the need for structural remediation of civilian infrastructure around the world is well known and a lot of research is being done in this field. Whenever new technologies are developed they are changes in factors contributing to the structure, such as increased load required, deterioration due to corrosion exposure to aggressive environments, changes in functionality, potential Fig -1:Modelling of XPD in Ansys Software damage caused by mechanical and environmental effects, increased strength and durability of the material. Today steel The objective of this paper is to evaluate the response of frame system with beams and columns becomes the bare frame and braced frame with XPD subjected to seismic conventional building structure in the construction world. loads and to identify the suitable size of XPD in brace frame Structural design and structural analysis are both of the for resisting the seismic load efficiently. criteria needed to create a structure that is safe perform its function of producing structures in stable conditions.
