At present, small radius looped prestressed tendons have been widely used in cable-stayed bridge anchorages; the error limitation of stretch elongation in prestressed technology is 6 percentage, but in field it always exceeds the limitation. In this study, the main factors which lead to the stretch elongation were analyzed through a field full-size model test of a cable-stayed bridge. Moreover, the behaviors of ring prestressed tendons were studied for different penetrating strands technology and some advices and suggestions were finally made to offer an example for similar engineering.

Concrete is used in tower, and steel is used in anchor zone. It can make full use of the two materials’ nature. It can not only satisfy the tower’s stressed aptitude, but also can reduce the cost of construction. In this paper, the full size model has been designed and constructed. The test investigation of the statical performance have been proceeded. The results show that the neotype anchor system can make full use of the materials’ nature and is in good working order. The anchor system with enough bearing capacity satisfies the operating requiements of the cable-stayed bridge.

Kollokvium om at udstille kunst og naturvidenskab. Steno Museet, Danmarks Videnskabshistoriske Museum, Århus, 25. september 2006. In the fall of 2006, the Steno Museum (Aarhus, Denmark) exhibited the installation Room One created by the American artist Rosamond Purcell. This installation consists of a full-size model of Museum Wormianum, the Danish physician Ole Worm’s curiosity cabinet, dating from the 17th century. This is a work of art – yet it depicts a naturalist’s laboratory. When one adds that it has also been called the first museum in Denmark, it seemed an obvious step to make the artwork the occasion of a symposium on the relationship between art, science and museums. At this symposium, the artist, along with a number of science historians and museum curators, discussed the definitions of art and science then and now, and spoke about the attempts to transcend the disciplinary boundaries that take place within the museums. Different ways of exhibiting were brought into focus, and Purcell’s installation formed the basis for many interesting discussions about the museum as a place of learning and of aesthetic experience.

In this paper the four main requirements for a propeller are dealt with. These requirements concern efficiency, cavitation, propeller-excited forces and stopping abilities. In a propeller diagram the characteristic efficiency curves for different conditions are explained. A comparison of the optimum efficiencies for various types of propulsors is given, and the applications on a 130,000-dwt tanker are considered. Cavitation-inception curves both for a specific propeller and for systematic propeller series are discussed. Predicted torque and thrust fluctuations, based on model-test data, and the results of measurements on the full-size ship are compared. Finally a quasi-steady testing technique, developed to analyze different types of stopping maneuvers, is described.

Main Component

A new method of measurement of the cable force in cable-stayed bridge model test is introduced. Pressure ring sensor is used as the main component in this method and the tension of the stay cables can be measured real-time and in time. It is vertified that this method is exact and credible by model test and can be used in actual cable-stayed bridge. The static measurements for the test model are conducted. The testing results are compared with the numerical results of finite element model developed for the test model. A platform is established for the future researchs.

Based on the working principle of vibration wire strain gauge, two influence factors were analyzed and the temperature correcting equation was given. Furthermore combined with the anchorage zones model test of Xiaoshawan Yellow River Bridge in Inner Mongolia, temperature correction coefficients of test dates were found by linear fitting function of MATLAB, and then the test datum were corrected that achieved very good effects.

Cable Stayed Bridge

Anchorage zone of tower is a key part of cable-stayed bridge. Some factors such as powerful local concentrated forces, anchor forces from prestressed steels and weaken factors from hole make this area in complicated states. Analysis of strength performance at the anchorage zone of cable-stayed bridge tower has been attracted attention in bridge engineering. Full-scale model test and force analysis was carried out when a typical cable-stayed bridge was selected as the research object. Three stress states of anchorage zone are consider, that is under prestressing, under cable forces in completion state and under maximum cable force. Analysis of stress distribution and force transmission route in these states will provide a scientific basis for design and research work for the future.
