[Size: 4.7 MB] ... ASDIP STEEL is structural engineering software utilized by engineers for design of steel base plate, steel and composite beam, steel columns, and other structural steel members. ASDIP STEEL is based upon the latest AISC specifications (AISC 360). ASDIP STEEL substantially simplifies time-consuming calculations for structural engineering design. Steel Base Plate Design: Base plates are elements required at the end of columns to distribute the concentrated load of the column over a much larger area of the material that supports it. The design of column base plates involves two main considerations: One, spread the load so as to maintain the bearing pressures under the allowable values, and the second is with the connection, or anchorage, of the base plate and column to the concrete foundation. The program performs the elastic design of a column steel base plate resting on a concrete support and subjected to any combination of axial load and bending moment, including uplift loading. The moment is assumed acting about the strong axis of a steel column welded to the plate. In addition, this program computes and checks the maximum bearing stress on the support, as well as the tension and shear forces per rod. The column may be eccentrically placed on the concrete support. For axially loaded base plates, such as those in frames assumed to be pinned at the base, the program is based on either the cantilever model or the Thornton method covered in the AISC Manual 14th Edition. For base plates with moment, two design theories are considered: a) For plates assumed rigid, the strain compatibility is enforced in accordance with the Blodgett method (“Design of Welded Structures”). b) For plates assumed flexible, the strain compatibility is ignored in accordance with the DeWolf method (“AISC.Design Guides # 1, Second Edition”). For columns subjected to axial tension or uplift, the Murray method is used. The anchor rods are designed per the latest provisions of the ACI 318 Appendix D “Anchoring to Concrete”, and includes checks for all failure modes in both tension and shear, interaction effects, and reinforcing design. Shear lugs can be designed as well. The input data required includes the plate, column and pier dimensions, the distance from rods to center of column, the materials properties and the acting service loads. Select the column properties and the anchor rod material from the built-in databases.
