APPLICATION OF RUBBER FOR BRIDGE BEARINGS

The report discusses the testing of rubber bearings in railroad bridge structures under dynamic stresses. Included in the testing were dynamic, static and tests at extreme temperatures. The tests showed that the modulus E of a bearing has no constant value; it depends on the loading, whereas the modulus G is practically constant. Static compression tests to failure generally gave high results except for the type of bearing with perforated reinforcing steel plates. The tests to determine the coefficient of friction gave the remarkable result that it is greater under low loads than under high loads. The tests on the various types of bearings have shown that repetition of vertical loading has a very much worse effect than repetition of shear loading.
