The deflection, the load carrying capacity, the stress intensity factor, and the fracture load of a slender column with fixed ends have been calculated. The column has a single-edge crack at the mid-section and it has an initial deflection. A crack reduces the flexural rigidity of a column. It increases the lateral deflection and decreases the load carrying capacity of a column. The lateral deflection at the cracked section increases the bending moment there, thereby it increases the stress intensity factor and decreases the fracture load. Author
