Numerical Approach to Assess the Performance of Concrete-Filled Steel Tube Stub Columns under Fire Hazards Abhishek Chand, Ramkrishna Dandapat, Dibyendu Adak, M. Longshithung Patton, Syed Bustan Fatima Warsi Journal of Structural Design and Construction Practice, 2025 Concrete-filled steel tube (CFST) stub columns made of various steel thicknesses and concrete types subjected to combined thermomechanical load were investigated using the finite element (FE) program, and optimization of steel and concrete for economic options was studied. The relationships among fire-resistance rating (FRR), critical temperature, load ratio, concrete grade, and steel thickness were investigated in this study from an economic and structural perspective. The strength and FRR of stub CFST columns with the same external dimensions can be kept in close proximity using larger concrete infills and thinner outer steel tubes instead of thicker outer steel tubes with thinner concrete cores, to make construction economical.
Structural Performance of Nanosilica-Blended Square and Circular CFST Stub Columns Dibyendu Adak, Abhishek Chand, M. Longshithung Patton, Subhrajit Dutta, Himanshu Bisht Practice Periodical on Structural Design and Construction, 2023 The study focuses on the structural behavior of concrete-filled steel tubular (CFST) stub columns with conventional cement concrete and nano-silica blended (doses of 4%, 6%, 8%, and 10% nano-silica by weight) concrete core infill of M25 grade under a pure axial compressive load. The strength and deformation capacities, as well as failure modes, of the CFST columns were assessed with reference to steel hollow and reinforced concrete (RC) stub columns. At optimum replacement of cement with nano-silica, the increase in strength from filling the hollow steel columns is about 1.6 and 1.5 times for square and circular sections, respectively. The addition of 6% nano-silica to the cement concrete core of CFST columns showed 2.55 and 1.19 times more strength as compared to RC stub columns with square and circular sections, respectively. As a result, adding nano-silica to the concrete mix increases the core’s axial compressive load carrying capacity and strengthens the nano-silica blended CFST stub column. The addition of the optimum doses of nano-silica increases the higher rate of hydration and rapid formation of hydrated products in the cementitious matrix due to its higher specific surface area. Due to its higher specific surface area, adding the right amount of nano-silica speeds up the formation of hydrated products in the cementitious matrix and makes the rate of hydration faster.
