The design/check of composite columns is seamlessly integrated within the program. Initiation of the design process, along with control of various design parameters, is accomplished using the Design menu. Automated design at the object level is available for any one of a number of user-selected design codes, as long as the structures have first been modeled and analyzed by the program. Model and analysis data, such as material properties and member forces, are recovered directly from the model database and are used in the design process in accordance with the user defined or default design settings. As with all design applications, the user should carefully review all of the user options and default settings to ensure that the design process is consistent with the user’s expectations. The AISC 360-10 composite column design options include the use of the Direct Analysis Method. The software is well suited to make use of the Direct Analysis Method because it can capture the second-order P-Δ and P- δ effects, provided the user specifies that a nonlinear P-Δ analysis is performed. Chapter 2 addresses prerequisites related to modeling and analysis for a successful design in accordance with “AISC 360-10.” Chapter 3 provides detailed descriptions of the specific requirements as implemented in “AISC 360-10.” The program does not check any of the specific requirements for seismic loading as required by the specification in the ANSI/AISC 341-10 code. The appendices provide details on various topics referenced in this manual. The user also should review the AISC Direct Analysis Method Practical Guide.
