This paper takes a sluice reconstruction project as an example. The constraint internal force, the related axis force, bending moment, and shearing force at the corresponding section are solved according to the unit stress and internal force balance. Furthermore, technology of mesh auto-generation in cross-section is utilized to plot the internal force graph of the structure directly, which will provide reference for reinforcement design and make it more convenient.

Part of the bottom column in the frame structure is buried in the soil,sometimes it should be considered the affects from the body of the soil when calculating the ground floor of the frame structure. The Winkler assumes is quoted in this article, as considering the coefficient of the Soil-column interaction, the equivalent height calculating formula of the column restrained by the earth is deduced , this can change the frame structure that restrained by the earth into the commonly structure to calculate. It illustrates that the restrained load by the earth in the bottom of the structure has the big affects on the internal force and lateral. It provides a simple calculating method for such structure.

Tunnels of new across the old one with short distance is the emphasis and difficulty in metro engineering development, which has great research values. According to the characteristic of deformation on overlap tunnels with short distance, we put forward the calculating model of lining deformation and internal force analysis. And deduced the formula of calculation on the new tunnel's construction to adjacent ones, then discussed and analyzed the settlement of the point of inflection on soffit lining and the greatest subsidence angle. We verify the theoretical formula about the reliability of the computation and rationality through a series of numerical simulation test against the background of Qingdao overlap tunnels.

Abstract For plane truss structure, starting from the analysis of ideal truss model, the influence of tangential deformation and angular deformation on the secondary internal force of the truss is fully considered through Python program. It is obtained through analysis that: in the ideal truss model, the Pδ second-order effect causes the member to produce tangential deformation and angular deformation, resulting in secondary internal forces. Numerical analysis shows that due to the influence of secondary internal force, the axial force error of ideal truss model can reach 19.731% and the secondary shear force is almost all the members of the truss, and the secondary moment only appears at the support. The research results have important reference value for the engineering design and high-precision internal force analysis of truss structures.

The rigidity calculation model for transverse joint of prefabricated utility tunnel is established by Midas FEA software based on physical guidance.Taking the prefabricated multi-utility tunnel of South Kemugong road of Guangzhou Intelligent City as the experimental object, the position of its transverse joint is analyzed from the aspects of construction and internal force. Midas FEA is used to establish and analyze the three-dimensional model for the transverse joint of the utility tunnel, and the calculation parameters, boundary conditions and loading methods of the materials are obtained, so that the calculation models for the bending and axial rigidity of the transverse joint are established.The results show that the theoretical calculation value of the model is consistent with the experimental value, and it can accurately describe the deformation and internal force state of the joint in the whole process of stress. The shear rigidity of the transverse joint is 3.524×106 kN/m and the flexural rigidity of transverse joint is 1.001×105 kN×m/rad under the condition of 500 kN/m horizontal axial force per linear meter.

Structured System

A steel footbridge with a 27m net span, a worm-shaped curve and a vine bridge style was proposed to be constructed in Diexi city of Sichuan, China. Considering the appearance and the functional requirement, the bridge is designed as follows: the section outline is composed of 21 different ellipse-shaped transverse ribs with 1.5m spacing, and the transverse ribs are connected by 12 longitudinal ribs. Comparison between two optional structure schemes is carried out. Considering the mechanical performance and economy, the structure scheme, a truss structured system at lower part of the bridge, is adopted. Internal force analysis, member design and deformation calculation of the structure are accomplished. Finite elements analysis with ANSYS shows that the welded joints can meet the bearing capacity requirement. Connection between the bridge and the foundation platform is also presented in this paper.
