装饰石材及其支撑结构抗震性能试验研究

天然石材装饰是新型的建筑物高级外装饰形式,随着经济发展,目前国内已经逐渐地在高层建筑中使用。由于没有经历地震的检验,其抗震性能为工程技术人员所关注。本项研究结合实际装饰石材工程,进行抗震性能试验研究。为此设计和制造了模拟楼房的试验支架,采用二种地震波对楼房进行动力反应分析,并将分析结果作为振动台输入,进行抗震试验。通过试验,检验了装饰石材的固定方式和支撑结构的抗震性能,有助于保障装饰石材的抗震安全。

The natural decorative stone is a new type of high quality ornamental material for tall buildings.Since there is no experience of decorative stones surviving earthquake,the characteristic of earthquake resistance is the concern of engineers.A dynamic test of realistic decorate stone has been carried out to study its seismic behavior.The test frame simulating actual building was designed and fabricated.Seismic response of building was analyzed by using two kinds of seismic waves.The analytical results were used as the input waves of shaking table.The fixing of decorative stone and the seismic behavior of bracing structure were examined through test and then the safety of earthquake is able to be ensured.
