为了研究点支式玻璃建筑中铸铝支承件的承载性能,对3种典型铸铝支承件进行了足尺模型试验研究。按照实际工程中支承件的形式与尺寸制造模具,采用ZL105-T1和ZL111-T6这种铝合金材料铸造成足尺模型试件,借助万能试验机对试件进行加载试验,得出了试件的屈服荷载与极限荷载。根据试件的实际几何尺寸与材料属性,建立有限元模型对试验过程进行数值模拟。有限元分析结果与试验数据吻合良好,验证了有限元模型的可靠性。试验研究与有限元分析表明铸铝支承件的承载力较高,可以在实际工程中应用。
In order to study the bearing capacity of cast aluminum support in point-supported glass building, full-scale model test was conducted on three typical cast aluminum supports. In accordance with the actual project support the form and size of the mold manufacturing, the use of ZL105-T1 and ZL111-T6 this aluminum alloy material cast into full-scale model specimens, with a universal testing machine to load the test piece, the test piece The yield load and ultimate load. According to the actual geometry and material properties of the specimen, a finite element model was established to simulate the experimental process. The results of finite element analysis are in good agreement with the experimental data, which verifies the reliability of the finite element model. Experimental research and finite element analysis show that the bearing capacity of cast aluminum support is high and can be applied in practical engineering.
