Abstract:In this paper, the consideration of system selection of long-span steel structure, and the structural analysis and design optimization of Lamellar-Kiewitt suspend-dome were studied. The first part of this paper summarized and classified all kinds of the long-span spatial steel structure system, and their main structural features, development, and application, advantages, and disadvantages were briefly introduced. Selecting the feasible system was considered based on architecture, structure, economy, and buildability index. The Lamella-Kiewitt suspend-dome is selected as the roof structure, and the static performance of the structure is obtained by nonlinear geometric static analysis, the eigenvalue analysis is carried out by subspace iteration method, and the response spectrum analysis is adopted for dynamic analysis of the structure. The axial stress in cable-strut, the overall deflection of the roof structure, and the natural frequency were satisfied with the Chinese design code. The structural optimization of the roof structure is studied under the various rise-to-span ratio, strut-height, and single-layer reticulated shell types. Analyses and optimization of suspend-dome in the paper were conducted with finite element software Midas Gen. From the result of optimization show that the total steel consumption of Lamella-Kiewitt single-layer suspend-dome structure with four hoop cables has a good economy. The study of this paper can provide a reference for the construction of a similar structure in the future. | |||

Abstract:Based on the experimental results of a stay cable model incorporated with a small size MR damper, a model consisting of the modified Bouc-Wen model in series with a standard model of a linear solid is proposed to predict the MR damper response attached to the stay cable. Using the experimental results of the stay cable with the MR damper and performance testing of the MR damper, dynamic properties of MR damper with constant current input coupled with stay cable is firstly studied. To carry out the semi-active vibration control of the stay cable model by using MR damper, dynamic analysis is carried out to predict the behavior of the MR damper with a continuously varied applied voltage to expect the achieved semi-active MR damper force. Dynamic analysis results is validated well by the numerical simulations of the measured experimental data. . | |||

Abstract:In the present paper, for stay cables installed with designed magneto-rheological fluid (MR) dampers of the Shandong Binzhou Yellow River Highway Bridge, a series of in-situ tests are conducted to investigate control efficacy of the cable free vibrations achieved by the semi-active MR dampers, Passive-off MR dampers and Passive-on MR dampers. Based on experiences and lessons from the systemically theoretical and experimental investigations of the Shandong Binzhou Yellow River Highway Bridge in China, one integrated smart damping control and sensing system for the stay cables vibration in cable-stayed bridges site based on microprocessor with the DSP chip is proposed and is carrying out on the Ningbo Zhaobaoshan Bridge in China. | |||
