Abstract ：
Cable truss structures are composed of edge cables and internal connection members. A common design involves internal members arranged in a continuous oblique pattern, which is efficiently employed in long-span space structures. This configuration primarily governs the equilibrium of free nodes through the curve of the edge cables. However, manually adjusting the prestress to align with the edge cable shape is challenging due to the variable skew angles of the internal members. To address this, this paper proposes a deep learn method to establish a mapping relationship among the edge cable curve, the coordinates of the free nodes, and the prestress distribution. The force density distribution is automatically adjusted by comparing the coordinates of the free nodes with the edge cable shape. Based on the curve characteristics of the edge cable, the polynomial power function is fitted using the least squares method. A deep neural network model with four hidden layers and Adam optimizer, using constrained node coordinates as input and force density distribution as output, successfully achieved the rational configuration of several typical diagonal cable truss structures. The edge cable shape of each cable truss can be controlled by automatically adjusting its configuration. This method is suitable for cable trusses with complex space topology and achieves a high degree of automation.

Abstract ：
In order to avoid the instability of compression support in annular space cable truss structures, a novel full-tension crossed cable-truss structure (FCCTS) is studied. Firstly, according to the geometric shape of cables, the distribution law of cable force in the pre-stressed state is deduced and analyzed by theory. According to the characteristics of the cable force of vertical cables being much smaller than that of upper and lower chord cables, a forming method of tensioning vertical cables, namely, the vertical cable-shortening method (VSM), is proposed. Corresponding node connection devices are also designed and tested. Subsequently, the VSM process for establishing tension is elaborated in detail, and its feasibility is numerically simulated and validated. The results clearly show that VSM can effectively establish the pre-stress state in FCCTS. The VSM has the advantage of low applied tension, making it easier to form structural tension.

Abstract ：
There are obvious differences in shape and space between the large-span spatial structure and the traditional steel structure, and there will be openings at the top of the spatial structure. However, there are few studies on the fire of the spherical dome large space building with openings at the top, which makes the classical plume model inapplicable. The axial temperature of the plume centerline predicted by the traditional plume model is quite different from the real results. Therefore, this paper investigates the temperature dynamics within large-span spatial structures during large-scale fire scenarios, utilizing a combination of theoretical analysis and finite element numerical simulations. It meticulously assesses how different natural ventilation inlet areas affect both the smoke exhaust capacity and the temperature field distribution within these structures. The research expands on the traditional plume model by introducing an enhanced formula for calculating the plume center velocity, specifically designed for large-span structures with top openings. Additionally, using an improved two-region model, the paper derives a logarithmic model that describes the temperature variation as a function of vertical height within the structure. This theoretical model is then compared with numerical simulation results. The study finds that increasing the natural ventilation inlet area significantly enhances the efficiency of smoke exhaust and reduces temperatures within the fire smoke layer of large-span spatial structures. The derived temperature logarithmic curve model shows high precision in predicting the spatial temperature distribution after the fire reaches a quasi-steady state, with an average relative error of 6% between predicted and simulated temperatures, confirming its accuracy. The conclusion is of great significance to the study of fire smoke movement in large-span spatial structures. The obtained logarithmic curve model of temperature under fire provides an important basis for the fire protection design of spherical dome spatial structures under natural smoke exhaust.

Abstract ：
With the gradual advancement of the country's environmental protection policies, the air-supported membrane structure, characterized by its short construction period, cost-effectiveness, and high safety during construction, has been widely used in the full enclosure renovation of open-air coal yards in coal-fired power plants, the construction of all-weather sports venues, logistics and warehousing, and has gradually entered a large-scale construction phase. The widespread application of air-supported membrane structures has placed higher demands on their operation, maintenance, and scientific monitoring. Taking a coal shed at a power plant in Hengshui city as an example, this article proposes the use of drones equipped with high-precision scanners to scan existing air-supported membrane structures and establish models. This method reduces the differences between the computational analysis model and the actual structure, enhancing the accuracy and reliability of the computational analysis results, thus providing support for the safe operation and maintenance of existing air-supported membrane structures.

Abstract ：
Cable -net structural design generally includes the initial state, load state, and zero -stress state, and adjusting design variables through manual intervention is difficult to correlate these different states. Thus, correlating the structural configurations among these states and finding the corresponding design variables is a challenge. By clarifying the relationship between the three states, a complete automated design process with three states connected by two new parameters is presented. Two typical cable nets are designed and validated, and the corresponding indicators are evaluated and recommended. This method can be applied to almost all flexible cable nets with constrained boundaries and provides an efficient way for designers to obtain reasonable results in the preliminary design stage. The proposed method expands the entire design path from initial form -finding to the load state and the zero -stress state, providing an important reference for the standardized paradigm and automated approach to flexible structural design.

Abstract ：
Cable-truss structure is a typical form of cable-strut tensile structures, which consists of upper cable system, lower cable system and several vertical struts. As with the general cable-strut tensile structure, only when the reasonable geometric shape matches the feasible prestress distribution can the cable-truss structure obtain structural stiffness and bear the external load. Once the geometric shape is unreasonable, the cable-truss structure is just a mechanism without bearing capacity and cannot be stiffened by introducing prestress. Consequently, a reasonable geometry is the premise for cable-truss structure to become an effective load bearing system. In this paper, an equivalent equilibrium force model, called EEFM, is proposed according to the geometric-mechanical characteristics of cable-truss structures. A cable-truss structure in this model is split into upper and lower cable systems with equivalent nodal forces. The geometric rationality can be easily evaluated from the equivalent nodal force relationship. According to the geometric topology and equilibrium equation of two cable systems, the self-stress mode of the structure with reasonable geometry can be directly obtained. For structures with unreasonable geometry, the node coordinates of one cable system are corrected based on the other cable system. Several cases are presented to verify the accuracy and validity of the proposed method. This method can be used for shape design, geometric correction and force finding, and has greater advantages for cable-truss structures with asymmetric or complex space configuration.
