工程位于洛阳市,建筑平面为不完整的圆环形,圆环角度243°,外环直径142.7m,环形平面中心线弧长约236m,建筑总高度40.45m,地上8层,地下1层。结构是由钢管柱和焊接H型钢梁组成的钢框架和多个钢筋混凝土核心筒组成。计算采用ANSYS软件,通过对结构整体施加温度作用,考虑了整体温度变化、屋顶阳光直射、地下室刚度等不同影响因素,得出了结构在温度变化时楼板、剪力墙、钢梁等各部分的温度变形和应力分布规律,楼板变形并不沿着弧线长度均匀变化,而是接近于沿外环直径均匀变化。根据分析结果为工程设计提了参考。
The project is located in Luoyang City. The construction plane is an incomplete circle. The angle of the ring is 243 °. The outer ring diameter is 142.7m. The centerline arc of the annular plane is about 236m long. The total height of the building is 40.45m. There are 8 floors above ground and 1 underground. The structure is composed of a steel frame composed of a steel column and a welded H-shaped steel beam and a plurality of reinforced concrete core tubes. By using ANSYS software, different factors such as overall temperature change, direct sunlight on the roof and basement stiffness are taken into account by applying temperature to the whole structure, and the influences of various factors such as floor slab, shear wall, steel beam and so on Temperature deformation and stress distribution, floor deformation does not vary along the length of the arc uniform, but close to the diameter along the outer ring uniform change. According to the analysis results for engineering design reference.
