Reinforced Concrete Coupling Beams with High-Strength Steel Bars
The use of high-strength steel bars in reinforced concrete coupling beams is expected to reduce reinforcement congestion. A series of tests was conducted to investigate the effects of high-strength reinforcement on coupling beam behavior. This document summarizes the test program and test data.
