The test parameter was the sub axial horizontal load intensity which was not cyclic but constant. All the specimens failed in a flexural mode. The peak strength of the cyclic load in the main horizontal axis decreased naturally as the load intensity in the sub horizontal axis increased. The interaction obtained due to bi-axial loading is discussed in comparison with existing design curves. 1 Introduction The Hyogoken-Nanbu earthquake at Kobe, Japan in 1995 revised the Japanese highway bridge design specification [I], in which the dynamic loading ca
