Presentation Abstract

The presentation will discuss two recent research efforts addressing limitations within existing seismic steel systems and post-disaster response of displaced populations. The discussion will focus on research into the seismic performance of non-orthogonal (skewed) special moment frame connections and a new post-disaster shelter structure concept for fast rebuilding in densely populated urban environments. 

The selection of an appropriate seismic steel system (braced frame, moment frame, shear wall, etc.) is often influenced by architectural considerations. Moment frame configurations offer the most architectural flexibility, but can be limited by code prequalification requirements that prevent the use of non-orthogonal beam-column connection geometries. Recent research on the seismic performance of skewed special moment frame connections having reduced beam sections will be presented.

Additionally, in developing nations, economic challenges, corruption, and lack of building oversight often prevent the implementation of modern seismic structural systems. As a result, earthquake hazards can lead to significant loss of infrastructure, displacing large populations. Implementation of emergency shelter relief in these urban environments of developing nations is particularly challenging due to high population density, building congestion, and integrated utilities and services. The presentation will discuss recent research efforts into a fast rebuilding paradigm suitable for urban environments in developing regions affected by natural disasters.
