Stability Analysis of an RC Structure with RC Shear Walls in the Event of a Fire

Vulnerability of Multistory RCC Framed Building with Shear Wall During Fire

“…Similarly, other models naming is done in the same manner to avoid the confusion. To compare the results a small part is consider which is marked in the Figure (1). The deflection and rotation have been obtained and compared in the considered portion of the models.…”

“…Reinforced concrete (RC) shear walls are considered as one of the lateral loads resisting structural members in RCC buildings. Apart from acting as a lateral load resisting system, the RCC shear walls tend to provide stability and stiffness to the structure (1) . The displacement of the structure exposed to higher temperatures (550℃ and 750℃) have reduced due to the inclusion of RC shear walls in the structure (1).…”

“…RCC elements exposed to fire generally suffer strength loss of the matrix by degradation of the hydrate structure and spalling or "shelling" of the concrete. Other important properties of reinforced concrete (RC) structures which deteriorate are loss in compressive strength, loss of elastic modulus, cracking and spalling of the concrete cover, reduction of yield strength, ductility and tensile strength of the steel and loss of the bond between the concrete and steel (1) .At temperatures of 550°C, aggregates begin to deteriorate. Unsound aggregate particularly siliceous aggregates having quartz polymorphically change with a volumetric expansion causes damage.…”
