Rural Masonry Isolating Structure and LRB Experiment: Seismic Resistance Properties and Statistical Data Curve Analyses

The low masonry structure is the most commonly applied building type in rural China. It is possible to install small‐diameter, low cost, and easily constructed laminated rubber bearing (LRB) components. Isolation technology has broad application prospects in rural buildings. We developed a small‐diameter LRB in this study wherein the isolation layer is set above the floor for easy installation and replacement. We built and tested 4 walls to observe the effects of different LRB thicknesses; we assessed test respective phenomena and seismic parameters accordingly. We ran another test on five small‐diameter LRB components with varying horizontal stiffness, different forms of shear strain‐equivalent horizontal stiffness, and postyield stiffness while changing the fitting formula for the second shape coefficient to give small‐diameter LRB design providing gist.
