In this study four strengthening methods for improving the seismic resistant ability of this problem are tested. These methods are developed under the condition that the original form is not changed. In method 1, a thin stainless steel strap is imbedded into the bottom face of the arch. In method 2, nine thin stainless steel straps with various lengths are imbedded into the brick joints horizontally. In method 3, two thin stainless steel straps are imbedded along the semi-circular joints of the arch. In method 4, eight thin stainless Z shape pieces are planted along the horizontal and vertical joints of often found damaged area. Totally, five specimens are manufactured and cyclic horizontal loading is applied. From these tests, the earthquake-resistant performance including damage mode, hysteretic loop, energy absorption and ultimate load are compared and discussed. Furthermore, the strengthening effect of post-earthquake strengthening is discussed for strengthening method 1. According to the test in the four strengthening methods, method 1 obtains a greatest value of ultimate loading and good stiffness however it has to cut a slot through bricks. In method 2 the loading resistance is not so high like method 1, but the original form is not interfered.
