Structural steel frames in new construction

We were recently tasked to work on new construction with structural steel frames. The scheme required large open spaces. This is becoming common in modern, industrial design. So, a steel frame was naturally needed for the superstructure. This was both for vertical loading and for lateral stability. The roof structure had a large section of a flat roof. But it also had atypical angled pitched roofs. These two elements presented a design challenge. We overcame this with several crank beams and cantilever beams to make it sound.

One other challenge faced was the limitations in terms of space for bracing. Consequently, many of the connections were designed as moment-resisting connections. We did this to allow the architect and client to achieve the required layout. Other bracing options would not have fit within the space available.

Initially, the client opted for a piled foundation. But; upon receiving the quotations from the specialist piling contractors, they instructed Simplify Engineering to provide a value engineering alternative for the substructure as well. The solution we offered was a combination of a shallow flat raft and several trench fill footings. This; combined with the structural steel frames solution provided, reduced their construction costs. This enabled project completion on time and within budget.
