某钢榫结构房屋地震模拟振动台试验研究

Shaking table test study of an integrated house with steel mortise-tenon connection

钢榫连接的新型集成房屋榫卯节点受力复杂,很难通过理论计算和有限元软件分析来评估结构抗震性能。对苏州某公司设计、生产的一栋单层钢榫结构集成房屋进行了足尺结构地震模拟台试验,通过对试验现象的观察和试验数据的分析,证实钢榫节点强度较高,连接可靠,在地震中无损伤,整体结构具有抵抗9级及以上大地震考验的能力,可以适用于高烈度地区。

As a new structural type, the integrated house with steel mortise -tenon connection has his characteristic technical superiority such as economical cost, simple design, modular production and construction. Involving complex structure stress and many difficulties in analyzing by traditional theories and FEM software, it is hard to define and assess seismic capacity of the buildings. So this paper consigned by a company in Suzhou studied the seismic behavior of integrated buildings by structural models with full scale on shaking table. Through simulated earthquake test on a shaking table, this paper analyzed the experiment data and phenomenon. The results proves that this type of composite joint had high strength and rigidity, and the house can resist 9 - magnitude earthquakes and is well suited to be deployed in earthquake stricken zones.
