Cross Section Analysis And Design is a powerful application that can perform a wide range of cross section calculations, including the design of reinforced concrete sections. It can handle any arbitrary cross section under biaxial bending and axial loads. The given cross sections are built up of one or more geometric entities and can be drawn directly using the versatile featured user interface. The user can also import standard steel sections from a complete shape library according to all major codes (AISC, Australian-New Zealand, BS, Chinese, European, Indian, Aluminum etc.) Among its capabilities, Cross Section Analysis And Design can calculate all sectional properties, plot Moment – Curvature and Interaction diagrams, estimate the location of neutral axis under given sets of biaxial loads and plot the corresponding stress – strain diagrams as well as the resulting stress contours. The last -named items can also be calculated by providing the location of the neutral axis plane on the section. Moreover, the program fully complies with all major codes concerning reinforced concrete sections (AASHTO, UBC, AS 3600, IS 456, ACI 318, BS 8110, CSA A233, EC2, NZS 3101 and CP 65). The user can also perform a reinforcement design according to above listed codes, plot the matching interaction diagrams etc., or even check a given reinforcement amount for the specified load cases. The stress – strain curve of concrete, reinforcement and other materials is specified as per the defined Analysis Parameters Sets. Thus calculations can be performed for many design situations, such as Ultimate/Serviceability or custom defined Limit States, with an automatic adjustment of the material properties, safety factors etc. A large material library is also available according to almost all concrete/reinforcement material specifications. Apart from concrete and reinforcement materials, the user can specify custom linear, bilinear, trilinear parabolic or fully general materials.
