PEC engineers Aldo McKay and Cliff Jones will be attending and presenting at the 2017 NCSEA Structural Engineering Summit in Washington, DC this week. This year, the conference is celebrating 25 years of bringing practicing structural engineers together for educational sessions, social and networking events and the Structural Engineering Awards Banquet. The full conference schedule is available here.

Aldo will be presenting on Evaluation & Retrofit of Existing Structures for Mitigation of Progressive Collapse. He will discuss the special design requirements intended to minimize the potential for Progressive Collapse (PC) for important government and military buildings. For new construction, these additional design requirements, while significant, can be easily incorporated into the design with proper planning and coordination. However, for existing buildings, structural upgrades can be expensive and challenging. This presentation will discuss the advantages of using advanced nonlinear dynamic analysis methods to maximize the contribution of the existing structural system including components often considered as secondary elements (such as slabs) in reducing collapse potential when performing alternate path (AP) analysis. In addition, design considerations for ductile structural upgrades of Reinforced Concrete structural systems will be discussed.

Cliff will be presenting on the State of the Practice: Blast Design of Building Facades and Structural Systems. He will discuss the philosophy of blast design followed by background information focused on identifying criteria, standards and references for blast design of building and facade systems. Typical approaches for defining blast loads will be presented followed by an overview of blast design and analysis approaches for typical facade and structural components. Finally, efficiency in design and overall project cost savings through additional engineering will be discussed.

In addition to presenting, Cliff Jones will also be participating in the NCSEA Code Advisory Committee on Resilience. This newly formed subcommittee develops positions and recommendations on issues in the emerging field of resilience-based planning and design. The committee coordinates with state and local efforts by SEA member organizations and works with other groups (including NIST, FEMA, ASCE, and ICC) to develop concepts of natural hazards resilience as they relate to the practice of structural engineering.
