Synopsis : In cellular sheet piling structures, connection sheet piles, required at the intersection of walls between are cells and circular cells, are subjected to the most severe stress and deformation conditions among structural components and so they may lead to fatal failures. For the purpose of studying ultimate strength of "T" connection sheet piles, which are used for almost all types of cellular cofferdams in Japan and developing new connection sheet piles with higher strength, a series of two directional simultaneous tensile tests were conducted by using several types of about one-meter-long prototype "T" connection sheet piles. For design purposes, test results obtained were illustrated as interaction curves of ultimate strength at connections concerning hoop tensions in circular cells and are cells for every structural details, and also estimation methods for ultimate strength of typical types of connections were discussed. Additional tensile tests were also conducted on three types of "T" connection sheet piles for newly developed straight web sheet piles with higher interlock strength than that of conventional ones. |
