Abstract:
The vulnerability of reinforced concrete (RC) building systems to progres
sive collapse has turned out to be a challenging trouble for professional
structural engineers so as to prevent total failure on account of nearby dam
age. The goal of this paper is to enhance the knowledge of such buildings’
behavior underneath several scenarios of misplaced columns at different
floor stages, and their capacity for progressive collapse. The homes had
been analyzed following the guidelines for progressive collapse evalua
tion and design organized by means of the general services administration
guidelines (GSA). The progressive collapse of a ten story structure sub
jected to a simplest gravity load is taken into consideration and the column
has been eliminated at one place and the spread damage is evaluated. The
progressive collapse study has been carried out by way of removing the
column at a diagnosed crucial locations (at corner, middle and at interi
or) as in line with GSA guidelines. Static analysis is done using analysis
program ETABS. For each case, the consequences were taken in terms of
demand capacity ratio (DCR) at critical section, and as a result the structure
has been assessed for it’s susceptible to progressive collapse. The availabil
ity of shear wall is made on the component wherein collapse occurred and
DCR values are mentioned. After imparting the shear wall to the structure,
the progressive collapse of the structure because of accidental load may
be controlled in order that the GSA guidelines recommended DCR value
would be within the range.
