Abstract. With the increasing advancement of industrialization, light steel has been used more and more frequently, hence stability and global stiffness of light steel structure has been received more and more attention. In order to find effective ways for enhancing connection strength and stiffness of light steel structure components, this paper gives an analysis of the force condition of light-steel plant under stressed-skin effect and the role of stressed-skin units in light steel structural component in such structure. Besides, this paper provides finite element analysis of the light steel structural components and probes into ways for simple design of light steel structure based on stressed-skin effect.

“…They classified this type of building as a truss structure system composed of rigid walls and a flexible roof (RWFD), established a simplified two-dimensional finite element model (FEM) to analyse the RWFD structures and proposed a basic formula to estimate the period estimation and a method for the seismic design of RWFD structures. Cao Zhenggang et al [12] analysed the influence of metal roof panels on the seismic response of reticulated shell structures based on a reticulated shell structure in Shenbei New District (Shenyang, China) and found that the seismic failure load of a structure notably decreased after the addition of roof panels. Zhou Yizhe and Zhang Yigang [13] used shaking table tests to analyse the influence of roofing systems on the seismic response of a cylindrical reticulated shell structure and found that the skin effect of a roofing system could improve its fundamental structural frequency and reduce its node acceleration response.…”

The seismic performance of a single-layer spherical reticulated shell is the key problem to be solved in the design and analysis of this structure. In previous studies, the influences of roofing systems on the seismic performance of shells were usually ignored, resulting in large discrepancies between the results of analyses and the actual stress states of shells. In this paper, the finite element analysis method is applied to a shell with a roofing system, and the applicability of the method is proven by static loading experiments. The influences of roofing systems on the seismic performance of shells are obtained from seismic response curves, the proportions and distributions of plastic members and the failure behaviours of the shells during strong earthquakes. The mechanism of the influence of the roofing system on the seismic response of a shell is revealed by analysing the damage of purlin joints and the energy consumption of the components of the shell. The relationships that describe the influence of different parameters of reticulated shells and roofing systems on the seismic response of the shells are studied, and the results show that the roofing system can greatly change the seismic response and failure of a shell under strong earthquake conditions.

“…However, these theoretical methods are proposed on some assumptions, in which the bending rigidity of the joint is defined as linear elastic springs [7,[11][12][13], which could not reflect the non-linear rigidity of the joint clearly. Cao et al [14] and Ma et al [15,16] proposed a numerical method to simulate the property of spatial grid structure with semi-rigid joints through defining the non-linear rigidity of the joints as non-linear springs. Based on this method, the first issue of the research on spatial grid structures with semi-rigid joints is seeking for an approach to predict or obtain the non-linear rigidity of the joints.…”

Threaded-sleeve connection (TSC) is a new type of semi-rigid connection for spatial grid structures. In this paper, bending behaviour of the TSC was analyzed and a mathematical model for prediction of moment-rotation behaviour was proposed. Firstly, experiments were conducted to investigate the bending performance and damage form of the TSC. The moment-rotation curves of the specimens were obtained as well. Then, solid finite element model was established through ANSYS. Comparing the theoretical analysis and experiments, it was observed that the numerical results agreed well with the experimental data, which indicates the feasibility of the finite element analysis method. Finally, the calculation formul as of the initial moment and the initial rotation of the TSC were obtained through MATLAB curve fitting. The shape parameter n was determined. Based on the Kishi-Chen power model, the moment-rotation model of the TSC was developed. Therefore, it will be possible to take into account semi-rigid analysis for a spatial grid structure with TSC easily and find the more actual behaviour of the structure.
