Abstract	Single-core and to a certain extent multi-core lead-rubber bearings have been extensively used in seismic isolation. Yet their behavior is not well understood and experimentation is required to obtain their mechanical properties. A recently developed and validated theory contributed to the understanding of the effects of heating of the lead core on the characteristic strength and ability to dissipate energy of these bearings. Additional results on the theory of heating of lead-rubber bearings are presented in this paper, including readily useable data on the rise of temperature in the steel shim and end plates of these bearings. The results may be used in the assessment of the validity of the theory of lead core heating in single and multi-core lead-rubber bearings and in recently developed multi-core lead-rubber dampers. Examples are presented (including some experimental data) to illustrate the application of the theory. The utility of the presented theory is to reduce the requirements for physical testing of lead-rubber bearings and dampers.
