The main intent of this research is to replace the conventional concrete frame with geopolymer concrete frame under lateral loading condition and to study the structural parameters such as ductility factor, energy absorption capacity, load carrying capacity and stiffness. The activator solution is used in the preparation of geopolymer concrete. The dimension of prototype frames components include beams and columns are 230 mm × 350 mm and 300 × 300 mm, respectively. The characteristic strength of geopolymer concrete is 40.45 N/mm2 and the elasticity modulus of geopolymer concrete is 3.35 × 104 N/mm2. The size of beams and columns of the ¼ reduced scaled model frame i.e. 170 mm × 120 mm and 200 mm × 120 mm, respectively and the length and height of the frame are 1400 mm and 2340 mm, respectively. The frame was tested under push and pull lateral loading condition. The experimental results are compared with analytical results using finite element analysis. The stiffness, ductility factor and energy absorption capacity of reinforced geopolymer concrete frame for the first storey are 2.61 and 2.01 kN/mm; 6.23 and 5.97; 1542.82 and 1291.80 kN mm respectively and for the second storey, the stiffness, ductility factor and energy absorption capacity values are 1.47 and 1.41 kN/mm; 6.724 and 6.29; 2732.5 and 1837.44 kN mm, respectively. The reinforced geopolymer concrete frame, thus, exhibits better performance against horizontal loading circumstances, which makes geopolymer concrete suitable for construction sectors. |
