heal.abstract	A method which determines the optimal design of Lead Rubber Bearing (LRB) systems based on a systematic use of the interrelations that govern the behavior of a single LRB is proposed. This is based on the assumption of constant velocity spectra and the analysis of a single degree of freedom system adopted by many design codes. The optimal cost of the bearing that consists of the cost of rubber and lead is determined by varying the external and the internal diameters together with the total height of rubber. Thus, numerical results are presented which are compared with those determined following a mathematical programming approach and their agreement is established.	en
