BEHAVIOR OF GEOPOLYMER CONCRETE WALL PANELS WITH SQUARE OPENING VARIATIONS SUBJECTED TO CYCLIC LOADS

Masonry walls are non-structural elements that can increase the stiffness and strength of building structures subjected to lateral loads. Reinforced concrete (RC) wall systems are structural elements that have been developed to improve structural performance. Because the use of large amounts of ceme...
