WHO IS STRUCTURAL ENGINEER An engineer with specialized

WHO IS STRUCTURAL ENGINEER • • • "An engineer with specialized knowledge, training, and experience in the sciences and mathematics relating to analyzing and designing force-resisting systems for buildings and other structures. " A structural engineer usually has one of two roles on a building project, as identified by CASE: The Structural Engineer of Record (SER) "perform[s] or supervise[s] the analysis, design, and document preparation for the building structure and has knowledge of the requirements for the load carrying structural system. " The SER is responsible for the design of the primary structural system, which is "the completed combination of elements which serve to support the building's self-weight, the applicable live load which is based upon the occupancy and use of the spaces, [and] the environmental loads such as wind, seismic, and thermal. " A Specialty Structural Engineer (SSE) "performs structural engineering functions necessary for the structure to be completed and who has shown experience and/or training in the specific specialty. " The SSE "is usually retained by a supplier or subcontractor who is responsible for the design, fabrication, and (sometimes) installation of engineered elements or by the general contractor or subcontractor(s) responsible for construction related services. " Common examples of such elements are precast or tilt-up concrete, open web steel joists, pre-engineered cold-formed steel or wood trusses, and metal building systems.

SE’s role in scheme of things.

What is new for an SE. • Emerging Issues • Structural engineers have a uniquely significant responsibility for protecting the public relative to the other design disciplines. Architectural, mechanical, and electrical system failures usually result in unattractiveness, poor functionality, discomfort and/or inconvenience. A structural system failure almost always has more serious consequences, even in the best cases, there are often substantial costs associated with correcting what is or could become a life-threatening situation. As a result, professional liability insurance rates for structural engineers have been increasing, leading to the creation of the Risk Management Program (RMP). In addition, efforts are underway to establish board certification at the national level and expand separate licensure at the state level to "raise the bar" of qualifications to practice structural engineering. • • • Design for Blast Resistance , Progressive/Disproportionate collapse of structures.
