The structure of eccentric degenerated 3-D shell element of thin-wall steel tube concrete composite structure and the connection with 3-D block isoparametric element has been discussed using finite element method. Without considering the intensity limit of delamination damage of the two materials, an integrated stiffness matrix is formed with the combination of stiffness matrix of steel-wall shell element and that of concrete spatial block element. In order to make the superposition rule may be used at the joint of 8-node curved shell element and 20-node block element, an eccentric 8-node shell element is constructed.

The contrast tests of 1 reinforced concrete(RC) beams and 4 RC beams strengthened with near-surface mounted carbon fiber reinforced polymer (FRP) strips have been carried out, under conditions of different damage degree of RC beams. It is mainly conducted to investigate the effects of FRP strips reinforcement of flexural strength. The experimental results indicate that significant strength on the ultimate load and rigidity of reinforced concrete beams can be realized by mounting FRP strips to the beams, and propagation of cracks were reduced obviously.

Abstract. This paper analyzes the problems about the development of Yunnan ports, based on the perspective of new public management service. And then, it uses the Balanced Scorecard to analyze the development strategy of the Yunnan ports, from the four dimensions which includes the finance, the customer, the internal process, and learning growth. The paper also offers a Balanced Scorecard Strategic Map to illustrate the path and main tasks of the strategy implementation.
