Base Plate Modeling in STAAD.Pro 2007 By RAM/STAAD Solution Center 24 March 2007 Introduction: Base plates are normally designed using code- base procedures (e.g. AISC-ASD). Engineers often run into situations where there are no codes available to design a particular type of a base plate or there are instances where base plate were simply over designed in the past and the engineer has to check the design of this old base plate based upon new loadings and make modifications as required. In these situations, an engineer may opt to do a finite element analysis on the base plate. STAAD.Pro 2007 is equipped with a lot of mesh Figure 2: Plan view of tank base plate generation and loading tools. The purpose of this document is to demonstrate how engineers can analyze base plates using STAAD.Pro 2007. We would like to thank Mr. Indranil Roy Chowdhury, P.Eng. from Hartford Installations, Missisauga, Ontario for allowing us to publish this document. Please note that this document assumes that the user has basic knowledge of STAAD.Pro and Finite Element Analysis. Exercise Problem: Figure 3: Elevation view of base plate stiffener 1.

The tank leg pipe diameter is 0.9ft and the thick
