Free Base Plate Calculator

ASDIP free online base plate and anchorage calculator allows you to check the maximum bearing pressure on the support, the tension and shear forces per anchor rod, as well as design of biaxial base plates. With this calculator you'll be able to do the following:

  • Design Steel Biaxial Base Plates and Anchorage
  • Calculate Bearing Pressures, Tension and Shear Forces 
  • Generate Graphical View of the Base Plate and Breakout Areas 
  • Full Version: Multiple load types, shear lugs design, anchor rods design, seismic provisions, detailed reports, custom load combinations, and more!
  • Trial Version: Same as the full version but with minor limitations, such as Print and Save. It lets you test all ASDIP software for 15 days.

ASDIP STEEL includes modules for base plate and anchorage design per the latest ACI 318-19 and AISC seismic provisions. You can also model Steel / Composite Beams, Steel Columns, Shear Connections and Moment Connections. The Base Plate module includes biaxial forces and moments for a number of load cases, and load combinations per ASCE 7 or User-defined. The software generates a plan view of the base plate with exact configuration of the bearing area, including partial bearing under biaxial loads. Design per either ASD or LRFD. The program generates graphics of the breakout areas for tension and shear. Exposed formulas and code references for granular checking are included in detailed calculations.

Start your Free Trial and experience everything that ASDIP has to offer! You'll be able to evaluate all software, including the retaining modules, for 15 days: includes packages for CONCRETE, STEEL, RETAIN and FOUNDATION design. Or place an order and upgrade to the Full Version. 

How to Use The Bate Plate Calculator

Welcome to the ASDIP free online base plate and anchorage calculator. This base plate calculator allows you to model a column base plate and anchor rods. Use the Geometry tab to enter the dimensions of the column, base plate, and concrete support. The base plate can be placed eccentrically on the support.

In the Materials tab specify the material properties for steel, concrete, and rebars. You can model up to 4 anchor rods at each end, and 3 anchor rods at each side of the column. Select the anchor diameter and material specification. The seismic provisions are disabled in this free calculator.

A number of different load cases can be specified for horizontal and vertical concentrated loads, and biaxial moments. Click on the Loads tab to specify the loads information, either a single set of pre-combined loads, or a full set of load cases such as dead, live, roof live, snow, wind, and seismic. For the latter option, the calculator will combine the loads per the ASCE 7-16 load combinations. Other load combination options, as well as the calculation reports, are disabled in this free calculator.

Base Plate Calculator

This base plate calculator can model base plates subject to biaxial loading, either in partial or full bearing condition. The Graph > Base Plate tab shows a plan view of the base plate and anchor rods, indicating the bearing pressures at corners, as well as the tension forces in each anchor rod. The bearing area is colored for easier identification. The user interface of the the free calculator will change dynamically with every selection.

Anchorage Design

This base plate calculator can model anchor rods in different locations around the column. Depending on the loads, some anchor rods may be subject to compression, tension, and shear. The program calculates the forces in each anchor rod and applies the ACI 318 anchorage design provisions. The options to specify anchor reinforcement for tension and shear are disabled in this free calculator.

Concrete Breakout Diagrams

An important feature of the beam calculator is its ability to generate the tension and shear concrete breakout diagrams for the specified load combination. See the Graph > Tension Breakout and Shear Breakout tabs. The diagrams conveniently show the shape and magnitude of the breakout areas, whose calculation by hand can be time-consuming for irregular or narrow supports.
