ASDIP STEEL Structural Design Software

​Design Your Steel Members and Connections Within Minutes


ASDIP STEEL structural design software is utilized by engineers for design of steel base plates, steel and composite beams, steel columns, and shear connections. ASDIP STEEL is based upon the latest AISC specifications (AISC 360 and AISC 341 Seismic).

ASDIP STEEL structural design software is also capable to design anchor rods and shear lugs per the latest ACI provisions.

ASDIP STEEL 4 now includes the ACI and AISC seismic provisions, Load combinations per ASCE 7-05 or 10/16, and Shear Connections.

Key Benefits of ASDIP STEEL

 I Love how you investigate features in the Steel Program that I have suggested. The latest feature of adding the 0.8 stiffness factor for the Direct Design method works great. Your Software really is First Class and you provide First Class Support.”

Beams are structural members that mostly work in bending and shear as a result of transverse loading. Other terms such as girders, joists, purlins, stringers, girts and lintels are often used. The compression flange, which is attached to the web in the plane of the beam, may or may not be laterally braced, thus the buckling concepts of compression members apply to beams as well.

Composite action is developed when two load-carrying structural elements, such as a concrete floor slab and its supporting steel beams, are integrally connected and deflect as a single unit. Since the concrete slab exists anyway and the shear connectors are inexpensive and easy to install, it is structurally advisable to use composite construction whenever possible.

ASDIP STEEL performs the steel beam design or composite beam design for single span, either interior or border, subjected to distributed and concentrated loads, as well as end moments. Two cantilevers may be modeled. The program computes the bending moments, shear forces, and vertical deflections per load combination, and compares them against the beam strength. The program computes the number and spacing of the shear studs or connectors required to develop either partial or full composite action, as well as the required camber.

This steel structural design software is based on the AISC ASD/LRFD methodology and calculates the shear and flexure strengths according to the AISC 360-10 Specifications (14th Ed. Manual). Load combinations per ASCE 7-05 or 10/16.


The required input data consists of steel yield strength, member length, and lateral bracing. In addition, for composite beams it is required the slab thickness and beam spacing. as well as metal deck and shear studs information. You may specify two partial distributed loads, up to six concentrated loads, and two end moments.

Either service or factored loads may be specified. Load cases are internally combined, or you may enter a set of pre-combined loads.



The design process is simple with ASDIP STEEL. First, enter your input data using the rich set of controls. Second, specify the design criteria, such as the allowable deflection and camber, shear connectors, etc. Then use the Design Manager to find all the steel sections that meet this design criteria. Sort the table if you wish, either by weight or by design ratio. Finally, when you select one of these winner sections, the corresponding properties are transferred automatically to your calculations.

I’ve used Mr Encinas’ software for designing composite steel beams, and found it easy to use, surprisingly flexible (for a “fill in the blanks” interface), and best of all, largely self documenting. I’m an engineer who always struggles with documenting calculations owing to time constraints. Being able to print out a nicely-formatted output that reflects a classic hand-calculation approach is a boon. I highly recommend this product."
