The text, drawing Liede Bridge as project background, gives a detailed analysis about the transfer mechanism of the cable tower, with the aid of analytic theory methods, FEM calculations and model tests. While these model tests and calculations show that, on one aspect, the cable tower meets design requirements and falls into a safe state under construction load and bridge load. On another, its theoretical values are in accordance with the test values generally. To illustrate that the cable tower's transmission is in line with the plane-stress problem in Elasticity Theory verifies the overall static performance in cable tower along with the theory of design calculation.

In recent years, the trimaran as a novel ship has been greatly developed. The subsequent large vertical motion needs to be studied and resolved. In this article, an experimental study for a trimaran vertical stabilization control is carried out. Three modes including the bare trimaran (the trimaran without appendages, the trimaran with fixed appendages, and the trimaran with controlled appendages) are performed through model tests in a towing tank. The model tests are performed in regular waves. The range of wave period is 2.0–4.0 s, and the speed of the carriage is 2.93 and 6.51 m/s. The results of the three modes show the fixed appendages and the actively controlled appendages are all effective for the vertical motion reduction of the trimaran. Moreover, the controlled appendages are more effective for the vertical stability performance of the trimaran.

Ship Model

One of the phenomena restricting the tanker navigation in shallow waters is reduction of under keel clearance in the terms of sinkage and dynamic trim that is called squatting. According to the complexity of flow around ship hull, one of the best methods to predict the ship squat is experimental approach based on model tests in the towing tank. In this study model tests for tanker ship model had been held in the towing tank and squat of the model are measured and analyzed. Based on experimental results suitable formulae for prediction of these types of ship squat in fairways are obtained.

AbstractThe dimensions of many water streams, which satisfy proper hydraulic conditions, may not be compatible with the designed dimensions of an irrigation work that needs to be constructed in some locations. The design requirements of such irrigation works may involve a contraction in the channel width in the required location. This contraction, of course, affects different flow properties and the scour hole formed downstream of these structures. Therefore, the present experimental study aims to investigate the effect of the transition angle and the contraction on the flow properties and on the scour phenomenon downstream water structures. Through 460 experimental runs, carried out on 20 experimental models, the study proved that, for an efficient hydraulic performance and economic design, the best transition angle (θ) for the approaches of water structures is 30° with a relative contracted width ratio (r = b/B) not less than 0.6.

The ultimate bearing capacity of deep foundations has been investigated for the case of a strong layer overlying a weak stratum. The studies are based on model tests using buried circular and strip footings for a range of layer thicknesses. Based on the previously developed bearing capacity theory, the punching shear coefficients and corresponding shape factors have been evaluated.
