This project quantified the improvement in structural behavior of reinforced concrete shear walls retrofitted with a new method that allows the walls to rock over the foundation and self-center after ...

The ACI Foundation’s Concrete Research Council (CRC) selected eight research projects to receive grants this year. The ACI Foundation is committed to progress in the industry by contributing ...

A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that ...

This second column taken from my new book Composites for Construction — Structural Design with FRP Materials (published by John Wiley & Sons Inc., New York, N.Y.) focuses on the design of concrete ...

Despite the severity of the conditions and applications they encounter, concrete crusher and mobile shear attachments are capable of providing hundreds of hours of useful operation — provided they are ...

Researchers have developed a more precise method to identify and monitor shear crack development in concrete using acoustic emission analysis across multiple stress conditions. Published in Scientific ...

Recent structural collapses, including tragedies in Surfside, Florida, Pittsburgh, New York City and Davenport. Iowa, have centered the need for more frequent and thorough inspections of aging ...

Score another small victory for more-constructible high-rises, especially in seismic zones. Results of recent load tests on a "sandwich" shear-wall assembly, designed to simplify and speed ...
