A structural engineer is poised to be the first to use steel fibers as structural reinforcing in the lateral-force-resisting system of a concrete-framed high-rise in a seismic zone. The application, designed to reduce reinforcing-steel congestion in shear-wall link beams and, perhaps, in shear walls themselves, is based on recent successful performance tests of SFRC link beams at the University of Michigan, Ann Arbor.

It also allows diagonal rebar to be smaller and more bendable, so it can exit
The growing need to collect, store and analyze the huge volumes of data collected from infrastructure project stakeholders is generating a new growth area for construction-sector firms, IT vendors and professionals.
