Nosenko O. Development of Scientific Foundations for Effective Engineering Design of High Efficient Steel Piling Walls

TThe Dissertation solves an important scientific and technological issue of designing piling walls for the deep-waterport hydraulic structures. The new concept of piling walls made of sheet piling section of high bearing capacity is developed. New sheet piling sections of steel pile exceed the load-carrying capacity of steel pilings 1.6 – 1.7 times.The concept is based on the rational distribution of material in the plane of the cross-section of the hot-rolled pile sheet pile profile, while the conditional flexibility of the flange is reduced in comparison with the analogue and the center of gravity of the flange shifts in the direction of the profile wall from the middle of their length. Two profiles of sheet piling sections with increased bearing capacity were developed. Larssen-7 (W = 5010 cm3/m of piling wall; W/G=14,8 cm3/kg) and Larssen- 7H (W = 5200 cm3/m of piling wall; W/G=17,0 cm3/kg). Two structures of cold formed profile of furring channel sheeting piles and cold formed profile of cylindrical cross section of the same load bearing capacity as hot-rolled sheet profiles of Larsen type have been developed.A new construction design of universal clutch of shaped tube with square cross section has been developed for the conjugate sheet pilings in the piling wall.
