Rational Understanding about Renaissance Path of China's Road and Bridge Engineering

Mao-run Feng,Zheng-song Zhao

Frontiers of Engineering Management 2014, Volume 1, Issue 1, Pages 42-51 doi: 10.15302/J-FEM-2014013

Abstract: At the turn of this century, China began the largest road and bridge development in the world, which has virtuously interacted with the social and economic development and has elevated the engineering technology to world-class level. Surveying the development of world transportation, and comparing the road and bridge construction efforts of Europe, U.S.A, Japan and China, general experiences of success can be derived as follows: It is greatly beneficial to give priority to transportation for economic development; it takes national strategy and social action to build up a transportation network; demand and innovation are the driving forces to upgrade road and bridge technology; management innovation and quality assurance can greatly improve development caliber. While rationally acknowledging China's transportation infrastructure achievements, we should reflect on issues with Chinese characteristics that have affected quality and efficiency, expose all construction practices that violate scientific law, overall management defects in road and bridge construction and maintenance, and search for new ways to strengthen social management and the creation of a healthy soft environment.

Extension Controller Design via Sliding Mode Control

Chen Jenyang,Wong Chingchang

Strategic Study of CAE 2001, Volume 3, Issue 9, Pages 48-51

Abstract:

In this paper, a novel extension controller based on the scheme of sliding mode control is investigatedBy integrating the essential concept of extension set theory with the sliding mode control , the robustextension controller can be easily realized.In this study, a basic extension controller is organized first without any specific expert knowledgeActually, the proposed extension controller is stable in the sense of the Lyapunov.

Correlation between tension softening relation and crack extension resistance in concrete

Xiufang ZHANG , Shilang XU ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3, Pages 323-329 doi: 10.1007/s11709-009-0041-2

Abstract: Changes of the material fracture energy consumption with crack propagation can be described by a crack extensionThe variation of the crack extension resistance is mainly associated with the energy consumption in theThe crack extension resistance is then a function of the softening curve, which is a basic mechanicalThe relationship between the softening curve and the crack extension resistance curve is then analyzedThe results indicate that the characteristic points of the crack extension resistance curve is closely

Adaptive Extension Controller Design for Nonlinear Systems

Wong Qingchang,Chen Zhenyuan

Strategic Study of CAE 2001, Volume 3, Issue 7, Pages 54-58

Abstract:

A design method for the extension controller is developed in this paper.The proposed adaptive extension control resulting from the direct adaptive approach is employed to directlyadapt the gain parameter of the extension controller.Unlike the fuzzy controller, only one linguistic — like level is needed in the extension controllerThe derivation shows that the proposed extension controller is stable in the sense of the Lyapunov.
