Book Description
Ice action on two cylindrical and conical structures, located side by side, was investigated in a small-scale experimental study to determine the interference on the ice forces generated during ice-structure interaction. The proximity of the two structures changes the mode of ice failure, the magnitude and direction of ice forces on the individual structure, and the dominant frequency of ice force variations. Interference effects were determined by comparing the experimental results of tests at different structure spacings.

Book Description
IUTAM-IAHR Symposium on Ice-Structure Interaction Professor Bez Tabarrok, Chairman of the Canadian National Committee (CNC) of the International Union of Theoretical and Applied Mechanics (IUTAM) invited Professor Derek Muggeridge to organize a symposium on ice structure interaction. Dr. Muggeridge readily agreed and prepared a proposal that was endorsed by the CNC and presented to the General Assembly Meeting of IUTAM for their consideration. This Assembly gave its approval and provided the local organizing committee with the names of individuals who were willing to serve on the Scientific Committee. Dr. Muggeridge became chairman of this committee and Dr. Ian Jordaan became co-chairman of this committee as well as chairman of the local organizing committee. The symposium followed the very successful previous meeting, chaired by Professor P. Tryde in Copenhagen, by ten years. Both symposia uti lized Springer-Verlag to publish their proceedings. The Faculty of En gineering and Applied Science at Memorial University of Newfoundland were particul{lXly pleased to host this prestigious symposium as it marked the twentieth anniversary of its Ocean Engineering Research Centre.

Book Description
A test system was developed and used to investigate ice/structure interaction with centrifugal modeling. The test system was designed to perform two main functions: (1) create a uniform ice sheet, and (2) drive a model structure through the ice sheet at a constant speed. Both of these functions were required to be carried out while on board a centrifuge. The ice sheets were created by applying vaporized liquid nitrogen to the water surface in a model test container. Freezing test results were used to establish a linear relationship between ice thickness and the square-root of the product of time and temperature. The relationship was used to create ice sheets of predetermined thickness. An electric motor mounted in the model test container was able to withstand the large inertial stresses associated with accelerations up to 100 gravities. The motor drove the model structure through the ice sheet at a constant velocity. Two small scale model test programs were conducted to determine ice forces on offshore structures and the usefulness of the centrifugal modeling technique to investigate ice/structure interaction problems. The first program was designed to investigate ice crushing forces against isolated vertical cylindrical piles. The model pile test results show good agreement with the results of other research programs. The second test program was designed to investigate ice bending forces against frictionless rigid conical structures. The test results indicate that centrifugal modeling may provide a means for scaling ice density for small scale model tests. Further, a comparison of the test results with the results of a theoretical analysis using plasticity theory shows good agreement.

Book Description
Marine Structures Engineering is designed to help engineers meet the growing worldwide demand for construction of new ports and the modernization of existing ports and terminals. It provides an authoritative guide to the design, construction, rehabilitation, repair, and maintenance of port and harbor structures. Each chapter is self-contained, allowing readers to access specific information. The Author draws on his extensive experience in offshore structure and port engineering to demonstrate evaluation, rehabilitation, repair, and maintenance of in-service marine structures. Also covered in detail are state-of-the-art approaches to: *marine structures in cold regions, with special attention to the role of ice loads, permafrost, and other ice effects *shiplifts, marine railways, shipways, and dry docks *offshore moorings *floating breakwaters *marinas *structures that protect bridge piers from ship impact. Offering practical information on all aspects of marine structures, this book serves as an indispensable resource to all engineers and professionals involved in design, construction, maintenance, and modernization of ports and harbors.
