Seismic Damage Causes and Strengthening Methods of Museum Free-Standing Cultural Relics

Abstract

To protect museum cultural relics, seismic damage causes as well as aseismic strengthening methods of free-standing museum cultural relics were studied in this paper. Museums, cultural relics and their bases were all considered to study causes of damage of free-standing relics. Shortages of typical domestic aseismic methods were discussed, overseas isolation techniques were introduced. Based on 2 typical examples, reasonable strengthening methods for museum cultural relics were further demonstrated. Results show that main damage causes of museum cultural relics under earthquakes relate closely to over strong earthquake intensity, shortage of strengthening measures of relic, destruction of showcase or museum building and so on; museum, showcase and relic are all important factors for aseismic strengthening of the relics. Besides, to effectively protect the relics, traditional strengthening methods have to be improved; development as well as application of new isolation devices is encouraged.
