  • Advanced Analysis of Braced Staggered Truss of Steel Structure
    DEStech Transactions on Materials Science and Engineering, 2017
    Co-Authors: Wen Wei Yang, Wen-shu Zhang
    Abstract:

    Based on refined plastic hinge, this paper considers the effects of second-order effects of structure plastic strength, geometric imperfection, residual stresses to the structure stability by modifying the Element Stiffness Matrix. In this study 12 story braced staggered truss systems were designed and their seismic performances were evaluated by the modified Element Stiffness Matrix. The results were compared with the seismic performance of conventional staggered truss systems. According to the analysis results, the braced staggered truss systems showed relatively satisfactory load-resisting capability compared with conventional staggered truss systems, the herringbone braces and symmetrical arrangement monoclinic braces are better to improve the lateral Stiffness.

  • Advanced analysis of staggered truss of steel structure
    Advanced Materials Research, 2012
    Co-Authors: Wen Wei Yang, Xu Hong Zhou
    Abstract:

    Based on refined plastic hinge, this paper considers the effects of second-order effects of structure plastic strength, geometric imperfection ,residual stresses to the structure stability by modifying the Element Stiffness Matrix. Use the modified Element Stiffness Matrix to analyze the force of the staggered truss of steel sturcture and compare the calculation results with ANASYS’s. Use the modified Element Stiffness Matrix to analyze interstory drift of the staggered truss of steel sturcture and compare the calculation results with K Jim’s. The result shows that the developed Element Matrix can accurately calculate the stability capacity and interstory drift of the staggered truss of steel structure. Design by advanced analysis method is the direction of the analysis and design of modern steel structure.

  • The finite Element model research of the pre-twisted thin-walled beam
    Structural Engineering and Mechanics, 2016
    Co-Authors: Chang Hong Chen, Yan Fei Zhu, Yao Yao, Ying Huang
    Abstract:

    Based on the traditional mechanical model of thin-walled straight beam, the paper makes analysis and research on the pre-twisted thin-walled beam finite Element numerical model. Firstly, based on the geometric deformation differential relationship, the Saint-Venant warping strain of pre-twisted thin-walled beam is deduced. According to the traditional thin-walled straight beam finite Element mechanical model, the finite Element Stiffness Matrix considering the Saint-Venant warping deformations is established. At the same time, the paper establishes the Element Stiffness Matrix of the pre-twisted thin-walled beam based on the classic Vlasov Theory. Finally, by calculating the pre-twisted beam with elliptical section and I cross section and contrasting three-dimensional solid finite Element using ANSYS, the comparison analysis results show that pre-twisted thin-walled beam Element Stiffness Matrix has good accuracy.

Firstly, based on the author previous literature on the flexure strain relationship, the paper deduces the Element Stiffness Matrix of the pre-twisted beam. Finally, by calculating the pre-twisted rectangle section beam example, and contrasting three-dimensional solid finite Element using ANSYS, the comparative analysis results show that pre-twisted Euler beam Element Stiffness Matrix has good accuracy.
