Structural Safety Analysis and Design of a Double-Layer Spherical Glass Dome
The glass curtain wall with shell structure has the advantages of beautiful appearance,good lighting environment and large space,and has been widely used in engineering.Generally,the span of curtain wall structure is relatively small,while the double-layer spherical shell glass dome has the characteristics of light weight,large span and beautiful shape.Therefore,taking a double-layer spherical shell glass dome project as the research object,3D3S software was used to analyze the safety of the structure under different load conditions and put forward the design points of the dome glass.The results show that under different load conditions,the maximum stress ratio of the dome structure is 0.82,and the maximum vertical displacement is 13.0mm,which has a good safety reserve space.Under long-term and short-term wind loads,the stress and deformation of the dome glass are small,which meets the design requirements.From the perspective of the practice of the dome glass,the point-claw curtain wall has the characteristics of high permeability,good safety,strong flexibility,environ-mental protection and energy saving,which can ensure that the cost is saved and the construction is convenient under the premise of beauti-ful appearance,so as to achieve good economic benefits.
