Based on scheme of Dalian gulf cross-sea bridge, in this paper, a 3-dimensional FE model for Self-anchored cable-stayed suspension bridge is established with finite element program and pile-soil-structure interaction is simulated by use of the equivalent embed fixation model. Based on the FE model, model analysis is carried out and the effects of pile-soil-structure interaction on dynamic behavior of long-span self-anchored cable-stayed suspension bridge are specially studied. Under vertical excitation, the seismic response analysis result considering that pile-soil-structure interaction was compared with that of without considering such interaction. The analysis result show that interaction reduced longitudinal displacement of stiffening beam in middle of main span and tower at bottom, moment at bottom of tower and auxiliary pier pile, but enlarged the moment of conjoining section between steel and steel beam. The research results provide some theoretical foundation to composite structure system. © (2011) Trans Tech Publications.

Based on the previous undisturbed frozen field test, the research and analysis on the Size effect of fracture toughness K IC of vertical crack and herringbone crack of undisturbed frozen soils specimens of test I is performed emphatically, and it is found the rules that it varies with volume change. Meanwhile, a theoretical prediction by using the Gray System Theory methods is made and the theoretical prediction results K IC has been gotten, which is compared with the results of the test and the error fits the accuracy requirement. Thus it has been made a meaningful exploration for the research method of Size effect of fracture toughness K IC of test I of undisturbed frozen soils.

The fracture energy release rate G∼C, which is the important parameter of ice pressure calculation model that is built on energy balance method, is the fracture mechanics performance of ice material. It is related with these factors such as ice material loading rate P , which must be measured by experiment. It is the experimental method of fracture mechanics used in this paper. These ice specimens on the different thickness loading rate P were tested with fracture mechanics method at low-temperature testing machine, to obtain the fracture flexibility change rate d/da(1/M) of ice body which contains pre-crack and the values of P-δ under different conditions of P, which could determine fracture energy release rate GC of ice body during the ice pressure generated, which provide the necessary experimental data to establish ice layer pressure calculation model for the application of energy balance method. © 2011 IEEE.

Reservoir revetment on cold regions are often frost damaged resulting from the joint action of low-temperature and cryogenic environment in winter, and then reservoir revetments are often broken to decline the usage function, even to lose the function completely. In this paper, practical problems in engineering were analyzed for the drainage pumping station of Tuanjie Reservoir. Based on traditional method in analysis and calculation, fracture mechanics was brought to make quantitative analysis and calculation on the problems of anti-freeze damage from the viewpoint of fracture mechanics. So as to put forward a new idea to resolve anti-freezing of reservoir slope protection on cold regions, doing meaningful exploration. ©2010 Society for Experimental Mechanics Inc.

The rehabilitation properties of intelligent concrete beam reinforced with shape memory alloys (SMA) is investigated. In this study, SMA strands, made of 7 single wires, are used to replace the steel bars in ordinary concrete beam. The test of single point loading at the mid-span is conducted on the beam. The experiment has three stages including loading, unloading and heating the SMA strands. During heating the SMA strands by electrical current, the crack width can be reduced by taking the advantage of the shape memory effect of SMA strands. The results illustrate that SMA is a candidate material for rehabilitation of reinforced concrete structures. © (2011) Trans Tech Publications.
