Abstract  

Load-bearing capacity tests of 10 stainless steel bolted joints for aluminum alloy members under elevated temperatures were carried out, considering the size of the core plate, cover plate and the bolt. The failure mode, deformation performance and ultimate capacity of the connection were derived from the test, which were performed under 20, 200 and 300℃. As results, temperature has influence on the failure mode of the shear connection. Corresponding numerical models were established using ABAQUS, and the analytical results agree well with the test results. The contribution of temperature, plate thickness, plate width, bolt diameter and end distance to the bearing capacity were further studied with the verified FEM models. The calculation formula for high temperature bearing capacity of the stainless steel bolted joint for aluminum alloy members was derived, and verified with the test results.

铝合金板件不锈钢螺栓连接的高温承载性能分析

完成10个高温下铝合金板件不锈钢螺栓双剪连接试验，考虑芯板尺寸、盖板尺寸和螺栓规格的影响，试验温度分别为20、200和300℃，研究抗剪连接的破坏模式、变形性能和极限承载力.试验结果表明：温度会影响抗剪连接的破坏模式.采用ABAQUS建立数值分析模型，得到的数值分析结果与试验结果吻合良好.进一步研究温度、芯板宽度、芯板厚度、螺栓直径和螺栓端距等参数对连接承载力的影响，拟合得出铝合金板件不锈钢螺栓抗剪的高温承载力计算公式，并将拟合公式与试验结果进行对比，验证公式的有效性.
