ASDIP STEEL Structural Engineering Software

​Design Your Steel Members and Connections Within Minutes


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

Now ASDIP STEEL includes the ACI and AISC seismic provisions. Load combinations per ASCE 7-05 or 10.

  • Quickly model your steel members with the simple and efficient graphical user interface.
  • Confidently optimize your design and comply with design Code provisions.
  • Impress clients and plan-checkers with eye-catching condensed or detailed reports.
  • Extensive documentation, solved examples, and blog posts to guide you throughout the software.
  • Use your valuable time wisely while ASDIP STEEL does the hard work for you.
  • Much, much more...


 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.”

Shear connections are typically used to connect beams to other beams or columns. Such connections transfer shear, with minimum rotational restraint, as opposed to moment connections.

This module performs the design of s shear connection subjected to vertical loads, based on the AISC ASD / LRFD methodology. It checks the limit states and design limitations according to the AISC 360-10 specifications (14th Ed. Manual). Either service or factored loads may be specified.

A typical shear connection is composed of three parts: support, connector, and beam. The support may be another beam or girder, a column flange, or a column web. The connector may be either bolted or welded to the support and to the beam. Typical connectors are single or double clip angles, single shear plates, or Tees.


The required input data consists of the geometry of support, beam, and connector. Beam can be coped at either flange. Connector can be either bolted or welded. Material properties of all components are required. Load cases are combined internally per ASCE 7-05 or 10. A single set of pre-combined loads may be specified.



The software calculates the capacity ratio of all applicable limit states. The effect of the load eccentricity on the bolt group is calculated per the Instantaneous Center of Rotation Method (ICR). In addition, the software performs the design checks required by the AISC per each connection type, and checks the geometric constraints.

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."
