In this research we conducted a sensitivity experimental study where we explored the dependency of the shear strain on the seismic properties of bearings, namely lead rubber bearing (LRB) and super high damping rubber bearing (SHDR). The factors studied were vertical pressure, temperature, shear modulus of the inner rubber (G value), loading frequency, and loading sequence. Six specimens were adopted, i.e., three LRBs and three SHDR bearings. A series of test plans were designed. The seismic characteristics of the bearings were captured through a cyclic loading test, which included post-yield stiffness, characteristic strength, area of a single cycle of the hysteretic loop, equivalent stiffness, and equivalent damping ratio. A whole analysis of variances was then conducted. At the same time, to explore certain phenomena caused by the factors, an extended discussion was carried out. Test results showed that the temperature is the most dominant feature, whereas the G value is the least contributing factor, with the effect of the loading frequency and the loading sequence found between these two. The increment of the post-yielded stiffness for LRB from 100% to 25% is a significant reduction from a low temperature to high one. The slope of the characteristic strength versus the shear strain for LRB under high temperature is larger than the one under low temperature.

Water lubricated rubber bearing is one of the most appropriate bearings widely used in submerged pump for drainage. The apparatus for studying the tribological behaviors of the water lubricated rubber bearings has been devised and established in the paper. The experimental studies on the tribological properties of the rubber bearings have been conducted under different load and velocity using the apparatus. Effects of load and velocity on friction coefficient of the rubber bearings have been estimated. The experimental results show that the friction coefficient decreases with increasing velocity; the friction coefficient increases at first and then decreases with increasing load; the friction coefficient increases sharply with the rising temperature. The experimental results also indicate that there is an appropriate bearing clearance which the friction coefficient is minimum.

FRP (fiber reinforce polymer) rubber bearing is a novel isolator improved from traditional laminated rubber bearing. Several specimens were manufactured to study the mechanic properties of FRP rubber bearing. Vertical experiments are conducted to study the compression capacity and compression modulus of the bearing and horizontal experiments are conducted to study the shear modulus and damping property of the bearing. Hysteretic curve and damping ratio of each specimen are derived from the experiments. The results show that the performance of FRP rubber bearing matches that of multiplayer rubber bearing but have good damping capacity.
