日本多震,建筑物的抗震性能普遍较高。但如同人摆脱不了衰老一样,随着时间的推移,建筑物的抗震性能会有所下降,所以日本十分注意定期给建筑物做“体检”。提起日本建筑,首先要提到其抗震建筑方法,即让地震产生的力不直接作用于建筑物,从而避免建筑物受损的方法。具体来说,就是把夹杂多层铁板的积层橡胶和减振器组合成抗震层, Japan more earthquake, seismic performance of buildings generally higher. However, as people can not get rid of aging, as time goes on, the seismic performance of buildings will be reduced, so Japan pays great attention to regularly make “physical examination” to buildings. Mention of Japanese buildings, the first to mention its seismic building method, that is, the force generated by the earthquake does not directly affect the building, thereby avoiding the damage to the building. Specifically, it is a laminated multi-layer iron laminated rubber and shock absorber into a seismic layer,
