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.

Influence Degree

The multi-grid composite wall has unique structural types, and its stiffness can be adjusted according to different anti-seismic requests and complex architectural style. Referencing the frame-shear wall structure, the cooperative work mechanism and shear-sharing ratio calculation method of frame-composite wall structure are studied systematically in this paper. Based on the fundamental theory of Timoshenko beam, the frame-composite wall structure is regarded as double anti-seismic system consisting of shear type frames and shear-flexural type beams. The fundamental differential equation is established by the continuous approach, and its analytical solution of displacement and internal force are derived. Then the practical computational method of earthquake shear-sharing ratio on the frame-composite wall structure is put forward, and the influence degree that the composite wall rigidity degenerates to the structure internal force distribution is explained through concrete examples.

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.

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.
