Bond Behavior of Reinforcing Bars Subject to Lateral Pressure

In this study the influcence of the lateral pressure on bond behavior of reinforcing barshas been investigaed experimentally. A total of 36 specimens has been tested at the laboratory. The tests have been carried out for the uniaxial and biaxial pressures of the intensities of 0, 5, 10, 20 and 40kg/$\textrm{cm}^2$. the compressive strengths of the specimens are either 360 or 520 kg/$\textrm{cm}^2$, and two kinds of bars, round and deformed, have been used. Based on the test results, linear regression equations have been proposed, and the comparisons between test results and the regression calculations have been made.
