SpColumn is a powerful application designed for the structural engineers that need to analyze and to compare multiple column designs for their projects. Download spColumn 4.81 - Free Download from Shareware Connection Software Portal. Equipped with latest American (ACI 318-14) and Canadian (CSA A23.3-14) Concrete codes, spColumn is developed to design and investigate any reinforced concrete sections subject to combined axial and flexural loads. SpColumn is widely used for design and investigation of columns, shear walls, bridge piers as well as typical framing elements in buildings and other structures. Formerly pcaColumn, PCACOL, and IrrCOL, spColumn investigates sections that are impossible to find on design charts or to do by hand. Moreover, the reinforcement detailing (bars distribution) is an important factor affecting the crack width.Upgraded to ACI 318-11, spColumn is widely used for design of shear walls, bridge piers as well as typical framing elements in buildings and structures. Also, the Egyptian code equation should limit the value of the mean steel stress as given by Eurocode equation to overcome the underestimated values obtained in the case of sections having low steel ratio. The study showed a large scatter among the different code equations, however, most of the code equations overestimate the effect of concrete cover on the calculated values of the crack width. The experimental data include some variables affecting the crack width such as steel stress, concrete cover, flexural reinforcement ratio and rebar arrangement. Also, to verify the accuracy of the building code equations and the equations developed by researchers a comparison against some experimental data available in the literature was carried out. The models include different parameters such as reinforcement steel ratio, steel rebar arrangement and reinforcement grade. To investigate codes’ provisions beside some equations found in the literature concerning the crack width calculation of reinforced concrete members subjected to flexure, five reinforced concrete rectangular models were investigated theoretically. Some building code equations and equations developed by researchers are used for the calculation of the crack width in reinforced concrete flexural members.
