Book Description
Just before spring breakup in 1972, 23 in situ tests were conducted on the Pembina River, in Alberta, Canada, to measure ice forces. These tests simulated an ice sheet pushing against a bridge pier. The apparatus utilized a hydraulic ram to push a 5 1/2-in. (14.0-cm)-wide vertical pile section horizontally against the ice sheet, which varied from 11.5 to 19.5 in. (29.2 to 49.5 cm) in thickness. The velocity of the pile was varied from 0.07 to 21 in./sec (0.18 to 53.3 cm/sec) by hydraulic flow control valves. Both flat and round piles were used to represent the pier. Some tests began with the piles a few inches away from the ice sheet, whose edge was cut flat. Other tests began with the pile in contact with the ice sheet. For some of the round pile tests, augered holes were used to provide better initial contact. These in situ test results were compared with the ice force measurements made by other workers on a nearby bridge pier during ice breakup. The in situ test ice forces were about 50% higher than the bridge pier test results. This disagreement was caused by a difference between the sizes of the piles and the size of the pier and a three-day warming of the ice before the ice impacted against the pier. (Author).

Book Description
In the programme of the symposium was written: "The International Union of Theoretical and Applied Me chanics has taken the initiative to organize the sympo sium. As the name of IUTAM implies, the organization brings forward achievements within the field of theore tical mechanics for application in science and engineer ing. According to the rules of IUTAM that only invited persons can attend, all lecturers and participants have been ap pOinted by the members of the scientific committee. To facilitate contact among the attending persons, it has been decided to restrict the total number to 85 persons including the lecturers. Only one session is planned, making it possible for everybody to attend all lectures. Most scientists and engineers have realized that the knowledge attained by extensive basic research is essen tial in order to solve technological problems. In the process of acquiring this knowledge we often fail to un derstand that scientific progress is only achieved by two main principles: (1) By studying the scientific litera ture and applying or improving the theories in order to predict behaviour and forces correctly, or (2) by re jecting existing theories and developing new ways to cope with the problem, resulting in a more differenti ated and, hopefully, more exact theory. Ice seems to be a simple material, but it is in fact so complex and strange that it is only in the latest dec ades that we have come to know some of the natural laws governing its behaviour.

Book Description
The complexities of designing piles for lateral loads are manifold as there are many forces that are critical to the design of big structures such as bridges, offshore and waterfront structures and retaining walls. The loads on structures should be supported either horizontally or laterally or in both directions and most structures have in common t
