Innovative Tools and Techniques
Modeling: Hinman Consulting Engineers has developed advanced 3-dimensional methods of analyzing the effects of explosions on a building. Not only does this add precision to the analytical product, the graphical representations provide the client with easily understood results. Below is an example 3-D representation of the existing window’s performance colored coded by window performance condition for an ISC designated Medium Protection Level Loading. For all GSA Risk Assessment/Retrofit Design projects, we commonly issue such images along with the corresponding STANDGARD report to create the most reader-friendly and technically accurate reports possible.

Our in-house software, Blast Analysis Modules (BAM), includes approximately 100 modules, which are used to determine explosive air-blast parameters and the resulting structural behavior of critical components including windows, walls, cladding elements, columns, slabs, beams and girders. Because every building has its own unique characteristics our models are designed with the ability to accommodate a variety of material properties, support conditions, connection details, air-blast parameters and geometries to most accurately predict the behavior of the specific building under severe loading conditions. Response is evaluated using numerical methods to solve the governing differential equations explicitly as a function of time. The models incorporate strain hardening effects, damping and non-linear material behavior. Output includes displacement as a function of time, peak displacement, ductility, support rotation, reaction loads and rebound effects.
