Hyperledger fabric-based consortium blockchain for construction quality information management

Botao ZHONG, Haitao WU, Lieyun DING, Hanbin LUO, Ying LUO, Xing PAN

Frontiers of Engineering Management 2020, Volume 7, Issue 4,   Pages 512-527 doi: 10.1007/s42524-020-0128-y

Abstract: Lack of trust has been an ongoing issue for decades in construction quality management, hindering the improvement of quality performance. The development of mutual trust depends on immutable, traceable, and transparent construction quality information records. However, current information technologies cannot meet the requirements. To address the challenge, this study explores a blockchain-based framework for construction quality information management, which extends applications of blockchain in the domain of construction quality management. A consortium blockchain system is designed to support construction quality management in which participants’ information permissions and lifecycle are discussed. Additionally, this study presents in detail the consensus process that aims to address the problem of information fraud. The automated compliance checking based on smart contracts is presented as well, aiming to assure that construction products meet regulation requirements. Finally, an example of the consortium blockchain network is visualized to validate the feasibility of blockchain-based construction quality information management. The research shows that blockchain can facilitate mutual trust in construction quality management by providing distributed, encrypted, and secure information records and supporting automated compliance checking of construction quality.

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 49-65 doi: 10.1007/s11709-017-0448-0

Abstract: A good understanding of the effects of galvanizing on the short- and long-term behaviours of steel components is essential for structural design. This review paper is motivated by a series of recent reports on cracking in galvanized cold-formed tubular steel structures and the limitations of current steel product standards and steel design specifications in this field. The steel-related and galvanizing-related factors, different pre-galvanizing countermeasures for brittle cracking and the available technical documents are summarized. An extensive bibliography is provided as a basis for future research and development in this field.

Numerical simulation of a new hollow stationary dehumidity blade in last stage of steam turbine

Youmin HOU, Danmei XIE, Wangfan LI, Xinggang YU, Yang SHI, Hanshi QIN

Frontiers in Energy 2011, Volume 5, Issue 3,   Pages 288-296 doi: 10.1007/s11708-011-0160-z

Abstract: As a result of adopting saturation steam and long blade, problems of water erosion of last stage blade for steam turbine become more prominent. In order to improve the operation reliability and efficiency of steam turbine, it is necessary to investigate the nonequilibrium condensing wet steam two phase flow and the dehumidity method. A wet steam model with user defined function based on FLUENT software was investigated to simulate the steam condensing flow in the cascades. The simulation consequences show that the pressure variations in simulation depict a good agreement with the experiment data. On the basis of the discrete phase model simulation results and experiment data, the efficiency of existing dehumidity blade with suction slot was calculated. A new stationary dehumidity blade was designed to elevate the dehumidity efficiency: the efficiency in the suction surface was increased by 21.5%, and that in the pressure surface was increased by 12.2%.
