完成了包括2 5Ⅱ级钢筋搭接焊、弯折 90°对焊焊缝不填满弯折圆弧处 ,以及弯折 90°对焊焊缝填满弯折圆弧处三种情形对应的三组结构抗拉承载力试验 ,试验数据表明 ,2 5Ⅱ级钢筋搭接焊、弯折 90°对焊焊缝填满弯折圆弧处不会降低2 5Ⅱ级钢筋焊接结构的抗拉承载力 ,弯折 90°对焊焊缝不填满弯折圆弧处将使2 5Ⅱ级钢筋焊接结构抗拉承载力大大降低 ,本文基于大型结构分析软件ANSYS的非线性有限元分析结果亦验证了如上结论。
Completed, including 2 5 Ⅱ grade lap welding, bending 90 ° butt weld does not fill the arc at the bend, and bending 90 ° weld bead filled with curved arc at three cases corresponding Tensile strength test of three groups of structures, the test data show that 2 5 Ⅱ grade lap welding, bending 90 ° bend weld weld filled with curved arc will not reduce the tensile strength of 25 Ⅱ grade welded structure Bearing capacity, bending 90 ° butt weld is not filled with curved arc will make 2 5 Ⅱ-class welded steel structure greatly reduce the tensile bearing capacity, based on large-scale structural analysis software ANSYS nonlinear finite element analysis results also Verify the above conclusion.
