FRAGILITY ANALYSIS OF HIGH-RISE BUILDING STRUCTURE

In general the most suitable choise in improvement of high-rise building structure against lateral loding is used steel bracing system. The use of steel bracing was potential advantage over other scheme like higher strength and stiffness, economical, occupies less space, add much less weight to existing structure. The use of steel bracing systems for strengthening seismically inadequate high-rise building was a viable solution for enhancing earthquake resistance. Almost all the software like ETABS linear or Nonlinear static analysis presented by RC structure. Main parameter consider fragility curves etc. It was found that all bracing system the lateral displacement of building very effectively. The fragility curves developed in terms of PGA for Limit state: slight, Moderate, major and collapse in lognormal distribution. The aim of study is development of analytical fragility curves for High-Rise Building structure. Exact analysis using ETABS software* (ETBS’09, a 30 days trial version 2015) is carried out for G+9 , G+14, G+19 building using X-bracing, V-bracing fragility analysis of high-rise structure.
