"Design strength and ductility issues need to be resolved," among other issues, says Kelly. The research also will confirm long-held assumptions about 60-ksi rebar that were based on judgment or past ...

The Stark residence foundation plan incorporates coordinated measures for reinforcement, water resistance, and site drainage. Footings will use rebar to increase tensile strength and load distribution ...

If structural engineers have their way, building codes will take a leap forward in the next couple of years to allow the use of higher-strength 80-ksi reinforcing steel in concrete shear walls in high ...
