摘要

摘要: 金属屋面系统常用于各种重要的地标建筑中，经常受到周期性的太阳辐射、温度变化和其他环境影响。通过试验研究温度场作用下直立锁边铝合金屋面系统的变形和应力分布规律，分析屋面板、支座和板肋在静力温度作用下的应力和变形特性，并通过循环温度加载测试评估屋面板的力学性能、变形和磨损特性。结果表明：随着温度的升高，板肋、支座、板底和板面的应力逐渐增加，应力集中现象明显，温度每增加1 ℃，屋面板温度应力最大增加约1.2 MPa。板肋应力最大，板面次之，板底应力最小，且各部分应力均在弹性阶段。屋面板热膨胀位移显著，屋面板纵向水平位移要明显大于板底竖向位移，最大纵向水平位移约20.4 mm。循环加载下，屋面板的磨损特性受循环次数的影响较大，最大磨损厚度约18.20 μm。

Abstract: Metal roof systems have been widely used in various important landmark buildings, and are often affected by periodic solar radiation, temperature changes and other environmental influences. The deformation and stress distribution of the standing seaming aluminum alloy roof system under the action of the temperature field were studied by experiments. The stress and deformation characteristics of roof slab, support and slab rib under static temperature were analyzed, and the mechanical properties, deformation and wear characteristics of roof slab were evaluated by cyclic temperature loading test. The results showed that with the increase of temperature, the stresses of slab rib, support, slab bottom and surface gradually increased, and the stress concentration was obvious. When the temperature increased by 1 ℃, the maximum temperature stress of roof slab increased by about 1.2 MPa. The slab rib stress was the largest, followed by the slab surface, the slab bottom stress was the smallest, and the stress of each part was in the elastic stage. The thermal expansion displacement of the roof slab was significant, and the longitudinal horizontal displacement of the roof slab was obviously larger than the vertical displacement of slab bottom, and the maximum longitudinal horizontal displacement was about 20.4 mm. Under cyclic loading, the wear characteristics of roof slab were greatly affected by the number of cycles, and the maximum wear thickness was about 18.20 μm.
