Seismic Design Methodology for Precast Concrete Diaphragms Part 2: Research Program

PurposeResearchers need to collaborate to address grand challenges such as climate change, poverty and sustainable food production. The purpose of this paper is to investigate how the researchers in a globally distributed research program interact to move their research forward.Design/methodology/approachThe authors interviewed 14 participants in the research program.FindingsIn spite of the spatial distribution of the researchers the output from the research program is predominantly collaborative; as much as 79 percent of the publications are co-authored by researchers from multiple countries. However, the researchers mostly work alone on their contributions to their joint work and spend minimal time interacting. This strategy of minimal interaction is punctuated by islands of intense interaction when they occasionally meet in person. Interaction feels natural, productive and satisfying to them when they are co-located but less so when they are distributed, probably because they experience technology-mediated interaction over a distance as somewhat impoverished. The interviewees mention that the minimal-interaction strategy incurs the risks of cracks in common ground and of misconstruing minimal interaction as lack of commitment. But the strategy is generally well-liked.Research limitations/implicationsThe experience of technology-mediated interaction as impoverished points to an explanation for the finding of less interaction in distributed than co-located research. It should be noted that the study is restricted to one research program.Originality/valueBy questioning widely touted recommendations for ongoing, regular and sustained interaction this study provides a fresh look at scientific collaboration.

1994 Northridge Earthquake

Observations on damage to concrete structures, due to the 1994 Northridge earthquake, are reported from a Canadian code perspective. Most of the damaged structures were older, nonductile, structures that do not conform to current design and detailing requirements. Concern is expressed about the seismic hazard of older Canadian structures having similar deficiencies. A significant number of parking structures suffered extensive damage and a number of precast concrete parking structures collapsed. Deficiencies in these structures include lack of proper diaphragm connections, a mix of gravity load columns with ductile framing, inappropriate number and distribution of shear walls, torsional effects caused by ramps, and the creation of short columns due to geometric features. This earthquake also demonstrated the deficiencies in connections of pre-1973 tilt-up structures. Key words: seismic design, earthquake, Northridge, structures, codes, concrete, precast concrete.
