The cyclic loading method was adopted to study experimentally on loading frequency

shear strain

the sequence of vertical pressure loading

shear modulus of inner rubber of isolator and temperature effects on the vertical pressure dependency of horizontal mechanical property of LRB with shear modulus greater than 0.8MPa.The degree of effect of above factors on the postyielded stiffness and yield force of LRB was analyzed

some fitting formulas were given

in which all kinds of factors were considered.Research results show that the effect of frequency of loading

horizontal strain and shear modulus of inner rubber of bearing on the vertical pressure dependency of LRB are small

sequence of the vertical pressure loading and temperature have a certain degree effect on them.As a whole

the post-yielded stiffness of LRB decreases linearly with the increase of vertical pressure

the yield strength increases linearly with the increase of the pressure.The error of the fitting empirical formula for the yield strength should be fully estimated under high pressure condition.
