Abstract
The use of High Strength CoCre 4 (HSC) in building sys- is increasing in most parts of the world to the many advantages it off en such as allowing the use of stnaller thereby increasing the area of usable floor space. The woll may openings for windows, doors and duct spaces for functional This is an experimental and analytica1 study of concrete walls openings. The main objective of the study the of high smmgtb concrete walls with openings for various load openj.ng configurations. An experimentaJ program including specimens was conducted. For better undemanding of concrete e!Thct. three of the fourteen specimens were made of Normal (NSC). The walls were clusified into four groups draw the necessary conclusions for the -y p1U’8111elers. The effect the selected p1U’8111etern on the walls with openings were and discussed in the form crncking, s1raln, ond the collapse For insight on the behavior, a nonlinear finite element analysis was test specimens and the wall cracl ing. strains ond loads were compared to those obtained from experiments. three pre-loaded wall specimens were selected for retesting after repaired. by Carbon Fiber Reinforced Polymers (CFRI’i}
