Abstract

Abstract: This paper presents the results of experimental work to evaluate the performance of a novel proposed retrofitting technique on a typical loess cave building. For this purpose, the unretrofitted loess cave specimen, scaled 1:5, were carried out by a shaking table test. The specimen is retrofitted based on the test results obtained from unretrofitted specimen tests. The corresponding retrofitted prototype tolerated peak acceleration of 0.52 g and did not collapse. And select engineering parameters for seismic assessment, study the seismic performance of the retrofitted loess cave and verify the retrofitted effect of the adopted seismic retrofitted scheme.
