Providing different type of bracing in the existing building structure under seismic load

This paper presented the influence of the providing different types of the bracing system in the existing building structure. The selected object of analysis is Timbul Jaya Plaza building that located in Madiun City Indonesia. The system of building structure is Moment Resisting Frame (MRF). Seismic loading analysis use equivalent static analysis base on SNI 1726 2012. Modelling and analysis of structure use computer software ETABS version 9.00. Aim of this research to compare the use of different types of the bracing system under seismic load. Type of bracing that analyzed is X-bracing, V-bracing, and Inverted V-bracing. Model of structure without bracing used as control. Result analysis known that the providing of X-bracing will decrease maximum displacement until 36.28 % compared with existing structure without bracing and increase the stiffness of structure. (paper)
