Importance of Steel Detailer in Structural Detailing and Shop Drawings

The Steel detailer is a key team member in any Steel building or structural construction. He interprets the instruction details provided in the design documents, produces fabrication drawings and generates material estimates and other relevant reports. This detail must be presented in a standard format as required by the fabrication crew and construction team.

Once the architect or engineer completes Structural design documents for a desired steel frame structure, the steel detailer takes over the design detailing work. Accuracy of structural design documents determines the ability of the detailer to rightly interpret and avail fabrication details. It is a medium by which the architect or engineer communicates to the detailer the sizes, locations, dimensions, loads and other specifications for every steel component involved in the project.

If the design drawings provided by the engineer are found to be inaccurate or imperfect, the detailing process suffers heavily. The detailer will then misconstrue the design purpose and detail all the components inaccurately. Fabrication of parts becomes inefficient and erroneous resulting in waste of time and money.

First all of the steel components used in the structure are staked into a single system and are detailed as per the design guidelines. Commonly detailed parts include steel beams, columns, handrails, joists, decks, roof trusses, braces and girders. Steel detailer prepares plans, elevations, sections, views and details from 3D models to completely visualize the desired steel structure. He may require some help from designers to develop beam, column and end plate connections along with special connection details on the Shop drawings.

It is heavily recommended that the detailer prepare all the shop drawings; it is the service he is trained for, and this is why he is paid for. Shop drawings must be thoroughly checked to ensure that all design and fabrication requirements, local codes and guidelines have been met. If the detailer fails to produce all the required details, fabrication will be delayed which results in added cost to all other trades involved, including the project owner.

Introduction to Steel Connection Detailing, Beam-Column Connections

Steel connections detailing (beam/beam or beam/column) is an important exercise when planning definite distribution of loads transmitted from one structure member to another. This article helps you to become familiar with the more simple ways of joining steel components like beams and columns in a building frame. Basic design routines used for steel connection detailing purposes are: flexible end plates, bolted angle cleats and fin plates. All three of these are the most useful for steel beam/column or beam/beam connections.

In steel connection detailing process connections are assumed not to transmit any load from the target beam to another beam or column and for this to occur the connection must allow a small amount of rotation. With web cleats this happens from slip in the connected members and buckling of the cleats. Fin plates and End plates are purposely constructed of relatively thin material that will deform rather than transmitting any considerable moment.

To reduce steel fabrication expenses, the BCSA (British Constructional Steelwork Association) has proposed a number of standardized angle web cleat, fin plate and end plate connections and you should follow this for building steel frames. These fittings will usually be made of Grade 43 steel. In general the tops of all the fittings are placed 50mm below the top of the beam and the first bolt row will be 90mm below the top of the beam. A standard bolt pitch of 70mm is applied wherever possible. These recommended standards need to be customized for small components and for heavily loaded members.

To form beam-beam connections it is essential to notch the top and sometimes the bottom of the supported beam to clean up the flanges of the supporting beam. The BCSA standards utilize a 50mm deep notch rather than the lowest notch depth specified in the property tables of steel section. BCSA proposes use of fully threaded bolts or screws which are appropriate for 80-90% of connections in a typical steel frame. This means that there will be threads in the shear plane of the bolt so the threaded area of the bolt is used in estimating its shear capacity.

When detailing steel beam connections or column connections you need to examine the CAD program output closely to make sure that the recommended design can be physically constructed and that there is sufficient room to tighten the bolts. All steel connections are only as strong as the weakest link - hence the information provided here will enable you to avoid major slip-ups in steel framing and building design.

Steel Detailing With Tekla Structures

If you are thinking about your first steel detailing software, or moving up to a full 3D modeling software, I'm going to inform you of my experiences using Tekla Structures as a steel detailer.

I attended a seminar on Tekla Structures and was very impressed with the direction this software was headed and the development team behind it was vast. If you are intending to learn this software I highly suggest investing the extra money in the training class.

Your working environment is a fully rendered 3D model so you can visualize any aspect of the model and see any possible problems that need special attention. The program is very robust and feature rich and can be overwhelming at first. After 10 years of use there is nothing I can not do in this program and have been a beta tester also.

The program handles all your connection needs by way of macros to execute on the selected members. The developers were kind enough to even give the user the ability to create custom components to suit your needs and can be made very intelligent to perform different tasks depending on framing conditions involved. Before this ability existed the user might have to learn C++ to develop their own custom intelligent macros but that is now a thing of the past and a very powerful tool.

Drawing creation is very simplified and can even be tailored to your needs, automatic and manual dimensioning possibilities. You can custom create your own customer templates for logos and bill of materials. Drawings can be printed to a variety of file formats and my personal favorite is Adobe's pdf format which also makes it nice for electronic transfer to your customers.

You can export all applicable cnc machine data file in either DSTV or Peddimat format. Fabtrol file export is also possible. There is also a vast assortment of import file abilities. The last project I did the architect used Autodesk Inventor and provided me with his files. I was able to import his 3D model in and use it as a template, worked wonders for accuracy.

There is far more to be said of this software and in my ten years this software has developed into a marvel and is still growing with a very large user base.
