Properties Uniformity Analysis of Cold Formed Steel Sheet Piling

Abstract:

Through analyzing the molding process characteristics of cold-formed steel sheet piling, mechanical testing and metallographic analysis was made on the curved position of the U-shaped cold-formed steel sheet piling , the following conclusions was drawn: Cold formed steel sheet pile was subjected to the complex cross-section cold roll forming process, resulting in the uneven performance of a steel sheet piling along the horizontal. For the open cold formed steel of asymmetric steel sheet piling and complex cross section, a simple test at flat panel location is difficult to represent the overall performance of cold-formed steel, therefore it is necessary to make a comprehensive performance test on locking. A test method to check the locking occlusion performance on the cold bending steel plate is put forward. The experimental tensile strength of the Q235 level of ordinary carbon steel production of cold-formed steel sheet piling locking bite is 66MPa.
