PROGRESSIVE COLLAPSE ANALYSIS OF TWO REINFORCED CONCRETE FRAME SHEAR WALL STRUCTURE

In this project, it is put forward to carry out a progressive collapse analysis of 2 models of G+9 storey Reinforced Concrete frame Shear Wall Structure, by considering sudden column removal cases at different locations according to GSA guidelines. A structural model of the structure has been modeled in ETABS v19.0.0. And loads are applied as per GSA guidelines for the assessment of progressive collapse. The structure is composed of 7 bays in both directions, 10 m distance between each bay in both directions. The total structure is designed and detailed by IS codes as a special moment-resistant frame linear static method of analysis is used. As per GSA guidelines four-column removal cases, one at a time on the ground floor has been studied, namely a Corner column, an Exterior column, and two interior columns. For all four cases, the linear static analysis method has been done and Demand/Capacity ratios (DCR) are evaluated. Member having DCR ratio greater than 2 will going to fail for alike column removal case. It is obtained from previous research that shear in a beam is not cynical in any case, columns are also not cynical in Progressive collapse. However, as per linear static analysis, it is captured that beams are going to fail in flexure.
