T6 should be 140MPa, while the aluminum profile specification should be 150MPa. Should that be the standard?Code for design of glass curtain wall... And the calculation formula of bolt connection, what is the compressive strength value of aluminum profile?Prawns help you, 3Q~
When the contact area of the fixture and the clamp decrease, the tension in the tensile process increases, and the change in the force area and bending moment, shear force, etc. will cause the increase of the local stress and the increase of bending moment.
Personal advice: 1. The degree of occlusion is enhanced by the gauge before stretching. Up and down / adjust the bearing, to prevent the deviation caused by the above results of the bearing.Check steel raw material is a batch product manufacturer. The factory certificate is the same.
In this case, not only is the bending deformation produced by tensile stress, it is a large part of the moment and shear, in a large error.
