Tips for Structural Engineers

Concrete Pryout Failure for Anchors

Anchors in concrete have several different modes of failure when subject to tension or shear loads.  Concrete breakouts in tension tend to get the most consideration since the calculations can be more complex depending on various geometric constraints of anchors or anchor groups.  For anchor groups in shear, concrete pryout may also be of concern, especially when anchors are short…read more →

Anchored in Knowledge: Resources for Anchors in Concrete

Is your library lacking in design examples for anchors in concrete?  Are you familiar with the code-required inspections and certifications for concrete anchors?  Designing anchors in concrete can be complex and time-consuming if done by hand. Given the ever-increasing utility and flexibility of post-installed anchors, having the best resources on your bookshelf can ensure all failure modes are considered, all…read more →

Statement of Special Inspections

For certain structural projects, special inspections are required by the code to ensure a high quality of construction. However, which elements require special inspections? How often are the inspections required and who is responsible for ensuring the are completed at the appropriate time during construction. In the July 2018 SE University session, Dave K. Adams, SE, from BWE, presented Project…read more →

Key Parameters for Classical Design Methods

Structural software has become a daily necessity for structural engineers; however, it can be to an engineer’s detriment if the fundamental concepts of structural engineering are not well understood.  Having a good understanding of how structures behave can prevent devastating errors that might be overlooked in a software program.  Using classical design methods, engineers can estimate the preliminary member sizes…read more →

Importance of the Weld Ductility Factor in Bracing Connections

When designing bracing connections, have you been using a weld ductility factor on welds subjected to shear and transverse loads to allow for adequate redistribution of stresses? Although there have been multiple tests and papers showing the importance of this factor, some engineers are still unaware of its necessity which can result in underperforming bracing connections. In the February 2018…read more →

Using Structural Software Successfully

How well do you trust the results of your structural analysis software?  Relying on software can save hours of design time, but using an inaccurate model can have devastating results.  Even the most experienced engineer can stand to be reminded of potential inaccuracies when using structural software, especially with the many changes made to building codes and in structural software…read more →

Resources for Wind Borne Debris Tested Assemblies

Wind-borne debris is without a doubt a very serious design consideration when approaching a storm shelter or safe room design.  In every tornado or serious wind event, there are devastating images of the effects from upturned trees, 2x4s, cars, and even large fuel tanks.  Designing for such impacts can be daunting, and present day engineering theory may not be sufficient…read more →
