The STUDY ON THE STABILITY ANALYSIS OF RC FRAME BUILDINGS

Abstract

Buckling is instability of column under compression, any axial member that supports compressive load. In most of the buckling analysis applied loads, structural properties and material properties are considered certain. The buckling load factor (BLF) or effective length factor (K-factor) is one of important parameters in design of column or beam-column members in framed structures and the stability design method based on this effective length is quite commonly used by practicing engineers for many years. The present study mainly deals with BLF that may affect critical buckling load. It is concluded that buckling of structure is a major factor in stability analysis and we need to study factors that may affect the buckling during design of structure. From the analysis, it is interred that as the loads on buildings increases the most critical value of BLF, as height of building increases the most critical value.
